Whats New in BobCAD-CAM V26?

See Video 3 - Whats New in BobCAD-CAM V26

Machining Jobs

The CAM Tree has been redesigned to handle the longtime customer request, allowing to only have the

appropriate type of job in the CAM tree. To improve even more on the work flow, programming begins

by selecting the type of job to create, and there is the ability to also add more jobs to the CAM tree.

CAM Tree Workflow

The entire CAM tree has been made easier to navigate. The right-click context menus have been

improved by placing items in locations that are more logical. These changes make navigating through

the machining process require fewer clicks to get the same result! In addition the new Collapse and

Expand Items options make it easier to get to individual toolpaths.

Copy and Paste within the CAM Tree

Added in addition to the Feature Save and Load, the ability to copy and paste Features and Operations

directly within the CAM tree, making for a faster method for duplicating work, without always having to

save the feature, and then load it back in.

Also note that the copy and paste of Features and Operations will work across documents!

Customizable Machining Features / Dynamic Operations

Previously the machining strategies were fixed in what types of operations were available. For both the

Mill and the Lathe, BobCAD-CAM has moved completely to a Feature based system. Now a feature by

definition is part of the CAD model, and pertains to the geometry. When you load your model, you can

choose any combination of Machining Operations to machine for one Feature.

Now if you want to drill a hole, but needed to use a smaller drill to predrill, there is no need to edit the

Tool Pattern, you can just simply just add another drill!

The dynamic operations also improve for 2 axis machining. You can now add several finish passes by just

adding more operations to the feature. None of the operations share parameters as they did in the past,

allowing complete control. You can have your finish operations start in a different location than your

roughing operations without using multiple features.

The dynamic operations create a large advantage in the 3 axis machining as well. Now instead of having

to create multiple CAM Features, and selecting the same model over and over again, you can simply

create one Feature, select the model once, and apply all of the 3 axis operations to that model.

BobCAD-CAM V26

Setup Sheets

You now have the ability to generate a Setup Sheet from within the software! This long time requested

feature has now been completed. Now the programmer can generate a sheet to give to his operator to

give him all of the data he needs to get the overview of the program. Information such as the program

data, stock and material data, tool lists, and operation data will all be available through an HTML report.

The other advantage of the way the setup sheets are designed is that they can be customized to display

only the data that is important.

Simplified Tool Pattern Dialog

The default operations that are available for a Machining Strategy are customized through the Tool

Pattern dialog. Even though you can modify what operations they are using on the fly, you can adjust

their defaults through the Tool Pattern dialog to make the system work more efficiently. There is added

support to import Tool Pattern files from previous versions of the BobCAD-CAM software, to make you

have not lost any work from the past.

Machining Order

The machining order can now be changed on the fly; you gain complete control over your operations

posting order. This works in conjunction with the current Post by Tool, Post by Feature options giving

complete control over the order in which your operations post.

Multiple Depths for 3 Axis Engrave Roughing

There is now a 3 Axis Engrave Rough which can utilize multiple passes.

Multiaxis Posting Options per Feature

You have the ability to modify more settings at the feature level this gives you more control over the G

code output.

Thread Milling Enhancements

The Thread Milling operation has been improved to support multiple hole or boss locations on the

model. Also, there is the ability to control the start angle of the thread milling toolpath, allowing you

finer control over their toolpath, as well as the ability to create multi-start threads by using multiple

threading operations.

Toolpath Patterns

The Toolpath Patterns have been enhanced to give you the ability to do multiple patterns on a single

operation, feature, index system, or machine setup.

BobCAD-CAM V26

Lathe CAM Wizards

The Lathe module in BobCAD has received a complete face lift to make it consistent with the exact

workflow of the Mill. The Lathe operations are all dynamic as well, and have the same exact CAM

Wizard flow as the Mill.

Lathe Stock Wizard

The Lathe module now has a Stock Wizard as well to help direct the flow of how machining should occur

inside of the BobCAD-CAM software. The Lathe Stock Wizard gives 2 different stock creation methods;

cylindrical and revolve. You can either simply enter the size of stock cylinder, or can create a custom

revolved stock shape.

Lathe Hole Making

The drilling in lathe now matches up exactly as mill, giving you consistency and power. All of the drilling

canned cycles and all of the same intelligence in Mill. The hole making strategies will also use the Cutting

Conditions to aid in setting the default values for each strategy. Another important note on this is that

the Drill tools are now shared with the so you no longer need to have duplicate tools across Mill and

Lathe libraries.

Available Drilling Operations:

Center Drill

Drill

Chamfer

Bore

Ream

Counterbore

Tap

Lathe Tool Library

The tool library for Lathe has also been redesigned to offer a more consistent feel like the Mill module.

Now all of your tools; drills, mill tools, and lathe tools are actually all contained within the same Tool

Library. In addition, the Drill tools are now shared across Mill and Lathe, making it easier, you no longer

have to duplicate the data in both Mill and Lathe.

System Requirements

For BobCAD-CAM to run efficiently it is critical that all necessary files are present on the computer.

BobCAD-CAM Uses the latest technology available, for this reason it is imperative that the Windows

System and Hardware drivers on the computer are up to date.

Before Installing BobCAD software, first insure that the computer meets or exceeds our system

requirements.

Windows (Minimum)

1GB RAM

128 MB Graphics Adaptor*

Intel or AMD Processors**

2GHz Processor

Windows Vista or Windows 7

Windows (Recommended)

o 6GB RAM

o 1GB Graphics Adaptor*

o Intel or AMD Processors**

o 2+GHz Processor (Multi-core)

o Windows 7 x64

Specifications -Recommended Vs. Minimum.

The Minimum specifications means that BobCAD-CAM software will open and work, the minimum

requirements do not gauge performance and stability. For BobCAD-CAM to preform reliably at its best, it

is highly recommended to meet or exceed the recommended specifications.

Note: Although initial testing has shown that BobCAD-CAM V26 runs on Windows XP SP3, Windows XP is

no longer officially supported.

*BobCAD-CAMs stability is dependent on the graphics card ability to process information, integrated memory

graphics cards may work but are not recommended.

ATI or NVIDIA graphics cards with dedicated memory are recommended. The graphics cards software driver

must be updated to the current software drivers released by the graphics card manufacturer.

**BobCAD-CAM is not supported on Apple Macintosh -based machines. Some customers have shown success in

running BobCAD-CAM in a Virtual Windows environment on Mac computers using Boot Camp. While the end user

may choose to run Windows on a MAC, this is not supported by BobCAD-CAM Inc.

Updating the Computer System

Even new computers usually require software and driver updates. These updates are released on a

weekly and monthly basis, before installing BobCAD software you should check that your Windows

system and graphics card driver are up to date to avoid future problems.

Should you not be able to do this for any reason do not worry, just proceed with the installation of

BobCAD and if a software stability problem arise you may need to re-visit obtaining and installing these

updates.

Windows Updates

Windows updates are necessary to insure a stable working environment for the BobCAD software to

perform. There are different kinds of updates. Security updates or critical updates protect against

vulnerabilities to malware and security exploits. Other updates correct errors that aren't related to

security, or enhance functionality.

Windows Updates are normally provided over an Internet connection, although there is provision for

updates to be installed on computers without an Internet connection. If your computer is not or cannot

be connected to the internet you should consult an IT professional for help with how to obtain these

updates. If the computer is or can be connected to the internet, then check for and run all of the

available updates from Microsoft. Your computer is up to date when you've installed the latest updates

for Windows and your programs.

To check for Windows updates, follow these steps:

In the Windows search type Windows Update without the quotes.

Open Windows Update by clicking on Check for updates.

If any updates are found, click Install updates. Administrator permission required if you are prompted

for an administrator password or confirmation, type the password or provide confirmation.

BobCAD-CAM V26

Updating the Graphics Card Driver

The graphics card driver is one of the most crucial dependencies for the software to perform properly.

It is a common misconception that Windows will update the graphics card driver. The graphics card

driver must be updated manually. To update the graphics card driver, the latest driver must be obtained

from the graphics card manufacturer.

To update the graphics card driver you will first need to know the make and model of the graphics card,

to obtain this information, In the Windows Search box type dxdiag (without the quotes) then press

enter. This will display a control panel that shows the processor, memory and graphics card information.

Write down the graphics cards make and model, and then search the internet to find the manufactures

website. Once you have found the manufactures website you can then follow their instructions on

downloading and installing the newer driver if available. If you are unable to locate a newer driver for

the cards you have do not worry as this just means you are probably already running the latest update.

The Machine Setup must be configured for your software to work properly.

Installing the Post-Processors

A Post Processor is the translator that formats the G-code output by BobCAD-CAM into the language

that your CNC machine can read. Post Processors can be found & downloaded from the BobCAD-CAM

website, http://www.bobcad.com.

How to install a Post-Processor

Open your web browser and go to http://www.bobcad.com. Click on Support and then Post

Processors.

Follow the on-screen instructions to use the post-processor wizard to download your post processor,

make sure to save the file. After the post processor has been saved to your computer, locate the file you

had saved and double click the file to begin the installation.

The post installation copies the post file to the BobCAD-CAM softwares post directory, its default

location is in C:\BobCAD-CAM Data\BobCAD-CAM V#\Posts\Mill.

NOTE: After the installation is complete you will now be able to locate the file when you need to access

it when setting up a machine. After Installation is complete there should be no visible change, proceed

to adding and configuring your machine.

Gathering the Machine Data Mill Only

In order to configure your machine there is some information you will first need to gather. The check list

on the next page will help you gather this information.

This is the file extension that the machine requires to load the NC program into the controller.

BobCAD-CAM V26

Direction Vector:

Most machines follow what is known as the Right Hand Rule when it comes to directions of

motion when using the Cartesian coordinate system. We will use the standard Right Hand

Rule as our base when comparing your machines movement to complete the following

questions. Please keep in mind that all of the following questions refer to the direction the

TOOL moves in the workpiece.

X axis Direction:

When you jog your machine in the positive direction does the tool move to the Right?

Yes__ / No__

(Yes = Tool Motion Matches Right Hand Rule)

Y axis Direction:

When you jog your machine in the positive direction does the tool move to the Back?

Yes__ / No__


Z axis Direction:

When you jog your machine in the positive direction does the tool move Up?

Yes__ / No___


BobCAD-CAM V26

8

Minimum & Maximum Values for Axis Travel:

X____ _____

Y____ _____

Z____ _____

The minimum and maximum absolute coordinates for each axis. These values are from the

rotation zero. This zero is a virtual machine zero used by BobCAD and is not necessarily the

machine home.

**To pull the values for the limits of the machine**

These measurements are done with the machine spindle empty.

X-Axis:

Line the center of the spindle up with the edge of the face of the indexer or the center of the

platter and set as zero. Now move the machine to the max positive then the max negative

amount in X. Record these numbers above.

Y-Axis:

Line the center of the spindle up with the center of rotation and set as zero. Now move the

machine to the max positive then the max negative amount in Y. Record these numbers above.

Z-Axis:

The BobCAD machine zero for Z is the face of the spindle down at the center of the rotation

axis. Move the machine to this position and set zero. Now move the machine to the max

positive then the max negative amount in Z. Record numbers above. If the machine cannot get

there, take as far down as it can and measure from center of rotation to spindle face. This does

not have to be exact. However you want it as close as you can get it. If needed can use ruler.

Now you can measure the Max positive movement in Z.

For instance the spindle can only come down to 3 above rotation center.

The max travel for Z is 15. Then record above Max Z = 15 and minimum Z= +3

BobCAD-CAM V26

Rotary Axes:

The rotary axes of your machine need to be correctly defined for the internal mathematics of

our post processing engine to function correctly. Again here we will reference the Right Hand

Rule for defining your rotary axis components and we will also define the prefix used in the G-

Code to operate them.

Like the X Y Z axes the rotary axes of a machine tool can be referenced using the standards of

the Right Hand Rule. The following image illustrates this as well as the following description.

Please note the following axis identification is not the prefix used in the G-Code but how we

identify the rotary axis components for building your machine. The prefix for each axis is

defined in the next section.

A axis This is a rotary axis that rotates around the X axis of the machine.

B axis This is a rotary axis that rotates around the Y axis of the machine.

C axis This is a rotary axis that rotates around the Z axis of the machine.

1st Rotary Axis Using the above image what is your 1st rotary axis? __A__B__C__

2nd Rotary Axis Using the above image what is your 2nd rotary axis? __A__B__C__

BobCAD-CAM V26

:

Direction of Positive rotation on rotary:

When facing the machine place a mark on the axis being rotated. Whether it is marker or tape

and rotate the rotary axis positive. When following the Right Hand Rule standard axis rotation is

counterclockwise when looking at the axis from the positive direction.

1st Rotary Rotation:

When you rotate the 1st axis positive does your machine rotate toward you in the positive

direction?

Yes__ / No__


2nd Rotary Rotation:

When you rotate the 2nd axis positive does your machine rotate toward you in the positive

direction?

Yes__ / No__

Rotary Centers:

1st Rotary Axis: ____ ____ ____

2nd Rotary Axis: ____ ____ ____

X, Y, and Z center of rotation point for each rotary axis.

Click Here for information on How to find the Rotation for the rotary axis.

BobCAD Machine Zero to Center Of Rotation:

This is a measurement from where we are going to define zero for our systems calculations.

This location is NOT where you have to define your work offset locations. The values for this

option will vary based on machine configuration. All values are measured with the 4th & 5th

axis of your machine at Zero location.

Table/Table For this machine type the values are measured from the center of the rotary

platter at the face of the rotary platter going to the center of rotation for the 4th & 5th axis

unit.

Head/Head For this machine type the values are measured from the face of the spindle to the

center of rotation for the 4th & 5th axis.

Head/Table For this machine type the values are measured in one axis from the face of the

spindle to the center of the rotating axis which tilts the spindle. The second rotation center will

be aligned with the spindle face so a value of zero should suffice, but values are available here if

necessary.

BobCAD-CAM V26

Rotary Axis G-Code Prefix:

1st Rotary Axis: _________ Example: A

2nd Rotary Axis: _________ Example: B

What is the prefix (letter) used to identify your rotary axes?

Minimum & Maximum Rotary Degrees:

1st Rotary Axis: ______ ______

2nd Rotary Axis: ______ ______

What is the minimum (- direction) and maximum (+ direction) travel limits for each of your

rotary axes?

Rotary Axis limits:

What is the limit of rotation for the rotary axis I.E. +9999.999 and -9999.999 or is there another limit? Or

is it unlimited. Distance before it has to stop and rewind.

Adding and Configuring Your Milling Machine (Tutorial)

This tutorial covers how to create a machine. Machine creation starts with a machine definition to

define each element of the machine. Then the parameters are defined for each element of the machine,

such as the moving direction and limits. The machine parameter values are used in posting. For each

element, geometry (.stl) files are added to define what appears in the simulation window.

There are two levels of machine simulation: Standard Simulation and Pro Simulation. If you have

purchased the 4 Axis Pro, 5 Axis Standard, or 5 Axis Pro module, then you have the Pro Simulation.

Regardless of what level of machine simulation you have, you must still create a proper machine

definition. The only difference is that with Standard Simulation, you cant add geometry items to the

machine definition that is used for simulation and component checking.

The following image shows the 4-axis machine that is created in this example.

BobCAD-CAM V26

The following image shows all of the individual geometry files (.stl), together in one Workspace. This is

shown to help you understand how each geometry item is aligned in the Workspace when creating the

geometry files for the machine. The second image, the view is made transparent and zoomed in to show

the coordinate system used to align the machine elements.

Adding a New Milling Machine

Step 1. In the CAM Tree, Right-click the CAM Defaults folder, and click Current Settings.

Step 2. On the left side of the Milling Settings dialog box, make sure that Machine Parameters is

selected.

Step 3. On the right side of the dialog box, in Machine, click Add.

Step 7. In the Machine Parameters group, define the parameters for your machine.

Locating the Machine Definition Files

Step 1. When you create a new machine, a folder is automatically created along with an XML file of

the machine definition, in the BobCAD-CAM Data folder. The default location is: C:\BobCAD-

CAM Data\BobCAD-CAM Your Version Number \MachSim\Machine Name.... This is the

same location in which the geometry files for the machine must be stored.

Step 2. For the purposes of this tutorial, the next step is to copy the geometry files from the default

machine that is provided by BobCAD-CAM.

Step 3. Open the following folder: C:\BobCAD-CAM Data\BobCAD-CAM V26 \MachSim. Notice the

folder named 4 Axis Example has been automatically created. If you open the folder, you

will see the 4 Axis Example.xml file that is created to save all of the machine information.

BobCAD-CAM V26

Step 4. Open the BC_4x_Mill folder, and select all of the files except the .xml file. Press CTRL+C to

copy the selected files.

Step 5. Open the 4 Axis Example folder and press CTRL+V to paste the copied files into the folder.

These files are now available to add to the Machine Definition.

The Machine Definition Dialog Box - Define the Axis Parameters

Step 1. On the left side of the Current Settings dialog box, click Machine Definition.

Step 2. Notice the Machine group in the middle of the dialog box. The machine tree shows all of the

machine elements that have been automatically created. This definition includes the linear

axes, the rotational axis, and the dynamic holder and workpiece elements.

Step 3. The items in the tree are used to define or modify the parameters of each component. For

example, in the tree, click Y. Notice on the right, in the Machine Data group, the parameters

for the Y-axis are displayed.

Step 4. The Direction and the Limits for the Y-axis must be defined. By default the Y-axis Direction is

defined by the vector X0Y1Z0. This defines the direction as the positive Y-axis. The machine

being built requires the vector to be negative. Under Direction, next to Y, click in the box,

and change the value to -1. The Y-axis vector is now X0Y-1Z0.

NOTE: The vector direction for the axes is determined by the type of machine. For machines that the

table (and not the head) moves in the X- and Y-axes, generally these values are negative. For

machines where the head (tool) moves in the X- and Y-axes, generally these values are positive.

The direction is determined by the relationship of the machine elements and which way they

need to move to make the tool move in a positive direction in each of the X, Y, and Z axes.

BobCAD-CAM V26

8:

Step 5. Under Limits, to the right of Min, click in the box, and type the distance that this machine

element can move along the defined direction. For this example, type -10. This defines 10

inches of travel in the negative Y-axis direction.

Step 6. To the right of Max value, click in the box and define the maximum distance that the

element can move along the defined direction. For this example, type 10. This defines 10

inches of travel in the positive Y-axis direction.

Step 7. Set the Initial Value for this element to represent the elements starting position. For this

example, type 0. This sets the initial position to the origin or zero location of the Y-axis.

Repeat this Process for Each Axis on your Machine

Add Machine Drawings to the Full Machine Simulation Module

When creating geometry, the files must be saved using the .stl file extension.

IMPORTANT: The Pro Simulation is an add-on module, it is included with the 4 Axis Pro, 5 Axis

Standard, or 5 Axis Pro modules. If you do not have Pro Simulation, you cannot add

geometry as shown in the following step.

Step 1. In the Machine group, right-click the top tree item 4 Axis Example, and click Add Geometry.

Step 2. In the Open dialog box, navigate to the 4 Axis Example folder, and select BC_4x_Mill_Rot-

X_Base.stl, and click Open.

Step 3. The geometry item is added to the tree. In the tree, click geometry so it is selected. In the

Machine Data group, next to ID, click the name (geometry) and change the name to

mh_Base. Because the prefix mh_ was added, the visibility of this item is changed using the

machine housing view toggle (in the simulation window).

Step 4. Notice that the parameters for the geometry item are displayed in the Machine Data group.

The parameters for the added geometry can be modified from this location. For example, if

you needed to change the .stl file, in the left column click Geometry. Notice that the icon

appears next to BC_4x_Mill_Rot-X_Base.stl. You can click to display the Open dialog box

and select a new geometry file.

BobCAD-CAM V26

Add the Y-Axis Geometry

Step 1. In the machine tree, right-click Y, and click Add Geometry.

Step 2. In the Open dialog box, select BC_4x_Mill_Rot-X_Y Axis Base, and click Open.

Step 3. The geometry item is added to the tree. In the Machine Data group, next to ID, select the

name (geometry) and type Y_Axis_Base.(Name MUST contain NO SPACES)

Step 4. Click Color, and on the right, click . In the Color dialog box, select a color for the element

and click OK. When you run simulation, the Y-axis base will be shown with the selected

color.

Step 5. In the machine tree, right-click Y, and click Add Geometry.

Step 6. In the Open dialog box, select BC_4x_Mill_Rot-X_X Axis Base, and click Open.

Step 7. The geometry item is added to the tree. In the Machine Data group, next to ID, select the

name (geometry) and type X_Axis_Base.

About the Dynamic Elements

The dynamic elements are the elements that can change with each program. The Workpiece Transform

contains the first set of dynamic elements in the tree. This transform includes the toolpath, stock,

fixture, and the workpiece. You do not have to define geometry for each of these items because they

are defined by each program that you create. This is also true for the Holder Transform elements. These

dynamic elements are automatically created for you when you create a new machine.

Step 1. In the Machine group, under the Workpiece Transform, click Initial stock. Notice the

parameters in the Machine Data group as with the other geometry items, you can define a

color for the element. It is helpful to define a different color for each element that appears

in simulation.

BobCAD-CAM V26

9F

Step 2. In the Machine Data group, next to Transparency, click in the box and change the value to

40. This makes the initial stock item that is shown in simulation appear with forty-percent

transparency. When this item is fully visible, it will still appear slightly transparent which

makes it easier to tell it apart from the stock or workpiece items.

BobCAD-CAM V26

Step 3. In the Machine group, under the Workpiece Transform, click Stock.

BobCAD-CAM V26

Step 4. In the Machine Data group, notice the name in the Geometry row. For each program that

you create, when you simulate, the stock.stl (and the workpiece.stl) files are automatically

created and placed in the machine's folder with the other geometry files (as shown earlier in

this example). These files are created using the defined stock and the selected geometry for

the program.

BobCAD-CAM V26

98

Step 5. In the Machine group, under the Holder Transform, click Tool. Notice the parameter

displayed in the Machine Data group. You can change the color for each part of the tool and

tool holder, as well as the transparency and reflectivity.

About the Collision Check

At the bottom of the Machine tree, there should be an item labeled CC. This is the collision check that is

automatically added to the tree when you created the new machine. This item defines the dynamic

elements that are included in the collision check.

Step 1. To add a collision check to the tree, right-click the top tree item 4 Axis Example, click Add

CollCheck, and click Tool-Workpiece. This adds a collision check to the tree that is

automatically set between the workpiece and the tool. The more geometry you add. The

more options are available.

BobCAD-CAM V26

9:

Step 2. In the Machine group, click the new collision check item (CC1). Notice the information in the

Machine Data group. There are three boxes displayed. The larger box on the left side

contains all of the items that are available to add to a collision check group. The two boxes

on the right, Group 1 and Group 2, define the items that are collision checked. Any items in

Group 1 are collision checked with the items in Group 2. The Workpiece-Tool collision check

that was added automatically places the Workpiece in Group 1 and the Tool is placed in

Group 2.

Step 3. To add an item to a collision check group, in the list on the left side, click the item to add.

Next to the Group box to which the item is added, click .

Step 4. To remove an item from a collision check, click the item to remove, and then next to the

Group box, click .

Step 5. If you add a User Defined collision check, no items are automatically added to the Group 1

and Group 2 boxes.

Step 6. To finish the machine creation and save the information, at the bottom of the Current

Settings dialog box, click OK.

Tool Cribs for Mill and Lathe

The Milling Tool Crib is comparable to the tool changer on a machine. It adds two advantages to the

milling system. First, the Milling Tool Crib can be loaded and saved before you create milling features.

When the milling feature operations are created, the system automatically selects the appropriate tool

from the Milling Tool Crib. Second, when selecting tools for milling operations, the tool crib shows all

tools that are currently defined. By having the tools already defined, you can eliminate the need to

search the Milling Tool Library.

To add tools to a tool crib, follow the instructions below.

To access the Milling Tool Crib, do the following:

In the CAM tree, under Milling or Turning Job. Right-click Milling or Turning Tools and click Tool

Crib. Use this method to view all the tools currently loaded in the Tool Crib.

Click on Add Tool From Library, and select the tool to add then click OK.

NOTE: In order to load tools into the Milling Tool Crib before creating milling features, you must create

the tools in the Milling Tool Library.

When tools are created in the Tool dialog box, of a milling wizard, that are not pre-loaded into the

Milling Tool Crib, the tools are then automatically added.

When the Milling Tool Crib is accessed by clicking Tool Crib from a milling wizard Tool dialog box, the list

automatically shows only the available tools for that operation type.
