About chaining Untrimmed entities

CHAINING Definition: Chaining is a process used to select a number of entities, (lines, arcs, points, splines etc.) Chaining is used when modifying or transforming existing entities or when creating a toolpath. The entities form a chain when the distance between two consecutive entities is less than the chaining tolerance (.0001 in the system configuration). When Chaining Geometry to create a toolpath it is important in certain circumstances to chain the geometry in the proper direction, as it will determine the direction the cutter travels when machining the part. Below is an example of how to select geometry using chaining method.

Note: To change the direction of the arrows just click on Reverse from the Chaining dialog box.

Chain Enable C-Plane and chain the bottom chains as shown

above. Press Esc to exit. Definitions: The chain Mask options speed up chaining for a large number of entities or when branch points are involved. They let you "pre-select" categories of entities to build your chain from. Mastercam provides Entity, Color, and Level. All the mask does is to block all the entities that do not match the mask criteria.


Page 81

Color Mask More about Chaining Options

Color Mask chains only entities that form a chain and have the same color as the first entity you chain.

Analyze Chain

Click on the Options button and enable Color and chain the top chain as shown above.

Press Esc to exit. Definitions: Closed chains allow you to select all entities adjacent to the selected entity in the forward and reverse directions until it reaches the end of a chain or a branch point. Open chains allow you to select a section of the chain by selecting the first entity and the last entity of the chain. Mastercam creates an open chain which includes all adjacent entities between these two points.

Section angle applies only to Section chaining. In Section chaining, Mastercam chains along a set of smooth curves. Curves that are less than the section stop angle are considered tangent for this chaining method. When Mastercam encounters an angle that exceeds the section stop angle or a branch point, it ends the chain. Ignore depths (in 3D mode) lets you chain entities that could form a chain (the distance between two consecutive entity endpoints is smaller than the chain tolerance) but have different depths. Start chain at point will start the chaining from a point that you create on an endpoint of an entity in the chain.


Page 82

Load Toolbar States

Allow surface edges in Single mode allows you to select, in single mode, the edges of a surface. Break entities in Dynamic sets the system to automatically break the entities at intersection while in Dynamic mode. Nested chains Sorting lets you choose different sorting options while selecting geometry that is completely contained within a closed boundary. You can speed up chaining using next closest. Choosing inside to outside sorts and chains the curves from the innermost to the outermost. You can sort the chains starting with the outermost chains using outside to inside. It also allows you to sort and optimize the chaining using optimize inside to outside or optimize outside to inside. Infinite nesting in area chains one mouse click chains all of the curves and points within a closed boundary. When unchecked, Mastercam chains the outer and inner boundary closest to the point you entered to define the area chain and any curves or points between the two. Reverse inner chains changes the direction of chaining for the inner chains. Sync mode allows Mastercam to break a chain into a number of separate chains for the purpose of creating the surface. The Sync mode option of the Chaining Options dialog box determines how Mastercam should divide up the chains. You may need to choose a sync mode if you have attempted to create a surface and found that it twists. Chaining tolerance sets the default chaining tolerance value. Plane tolerance sets the default plane tolerance value.

Note that the PowerPoint presentation shows another way of setting the toolbar.

MACHINE TYPE Selecting the correct machine is an important step in CNC programming. It will automatically have the Machine definition, the Control definition and the Post processor linked to generate the specific code required by the CNC machine tool. Definitions: Machine Definition describes the components of the machine tool and their interrelationship and motion. Control Definition provides the post processor with the information it needs to process the toolpath. Many of the settings in the control definition replace the numbered questions found in posts for earlier versions of Mastercam, so that settings that previously required editing the .PST file should now be set in the control definition. Post Processor refers to the process by which the toolpaths are converted to a format that can be understood by the machine tool's control (for example, G-codes).

MACHINE GROUP PROPERTIES Machine group properties include selecting the machine tool that will perform the operations in the group; post and NC settings; tool offsets, default settings and data paths; and setting up stock models and safety zones that will be used by all operations in the machine group. A single part can have multiple machine groups, each containing machining properties folders that identify properties (i.e., support files, tooling, stock, etc.) The functions in this dialog box are divided into four tabs: Files tab allows you to specify the names and data paths of the files needed to generate the toolpath. It also allows you to set the operations defaults. Tool Settings tab allows you to control how Mastercam assigns tool numbers, tool offset numbers, and default values for feeds, speeds, coolant, and other toolpath parameters. Stock Setup tab allows you to define the stock shape and size to use it when verifying the part using Verify. Safety zones tab allows you to define an area around the system origin to allow the tool to retract a safe position outside this area to avoid collisions caused by indexing. It is used mainly with multiaxis toolpaths.

Right click in the Toolpaths Manger area and select Mill toolpaths and then Contour.

Definition: Toolpath Parameters tab allows you to select a tool, set feed rates and speeds and set other general toolpath parameters. This tab is the same, or very similar, for most Mill toolpaths. For a detailed explanation of the parameters please check the PowerPoint: Lesson11a.ppt Definitions: Contour Parameters tab allows you to enter cutting parameters for a contour toolpath. Clearance value sets the height at which the tool rapids to or from the part. Retract value sets the height at which the tool rapids/feed-rates up to, before the next step down. Feed plane value sets the height from which the tool plunge-rates into the part. Depth value sets the final machining depth for the drilling operation. Top of stock value sets the height of the material. Compensation type set to Computer allows Mastercam to compensate the toolpath, and doesn’t output G41/G42 in the code. Compensation direction set to Right offsets the toolpath, with the radius of the tool, to the right side. Roll cutter around corners set to Sharp inserts arc moves around corners in the toolpath. The radius of the arc moves is equal with the radius of the tool. Infinite look ahead prevents the toolpath from crossing itself (fish tail).

Simulate tool and holder: Displays a tool and holder as a solid.

DRILL TOOLPATH Definition: Drill toolpath allows you to drill holes in the part using different cycles that the CNC machine tools are capable of machining. To select the Drill Toolpath you can use one of the 3 options as described in the Contour operation.

Note that the Toolpaths Parameters tab is similar with the contour toolpath. Drill Parameters tab allows you to select a drilling cycle and enter basic drilling parameters. Clearance value sets the height at which the tool rapids to or from the part. Retract value sets the height at which the tool rapids/feed-rates up to, before the next step down. Depth value sets the final machining depth for the drilling operation. Drill/ Conterbore cycle (G81) is recommended for drilling holes with depths of less than three times the tool diameter. Peck Drill is recommended for drilling holes with depths of more than three times the tool diameter. Retracts fully out of the drilled hole to remove material chips.

Bore #1 drills holes with feed-in and feed-out motion. Bore #2 drills holes with feed-in, stop spindle, and rapid-out motion. Fine bore (shift) stops the spindle at the end of each drill point, then spins to orient the tool to a pre-defined angle, shifts off the wall of the hole, and retracts. Tip comp: adds the tip of the tool (automatically determined based on the tool diameter and the 118 degrees angle of the drill) to the depth. You can also add a breakthrough amount to the depth for the tool to drill all the way through the stock.

POST PROCESSING Definition: Post Processor refers to the process by which the toolpaths are converted to a format that can be understood by the machine tool's control (for example, G-codes). Output MCX file descriptor allows you to include a description of your file. NC file allows you to save your file. Ask prompts the user if you wish to overwrite the file name. Send to machine sends the NC file automatically to the machine’s tool control through your workstation serial port. Edit allows you to edit the program. NC extension prompts for the extension to be used for the NC files. Overwrite automatically overwrites a file with the

same name without asking permission.

Tips: You can draw the sphere by clicking in the graphics window to set the base

point, dragging outward to set the radius. While the sphere is live you can change the base point, radius, and sweep angle.

Create the torus. Create

Primitives Torus

Tips: Use different color to create the torus. You can draw the torus (in Isometric

view) by clicking in the graphics window to set the base point, dragging outward to set the major radius. After setting the major radius, enter the minor radius. While the torus is live you can change the base point, major and minor radius, sweep angle and the axis.

Create the cylinder. Create

Primitives Cylinder

Tips: Use different color to create the cylinder. You can draw the cylinder (in

Isometric view) by clicking in the graphics window to set the base point, dragging outward to set the radius, then dragging up or down to set the height. While the cylinder is live you can adjust the dimensions, extend the cylinder in two directions, select a new base point, change the primary axis, or change the sweep to create a slice of a cylinder.

Draft Surface

DRAFT AND EXTRUDED SURFACES Definition: A Draft Surface is a surface generated by extruding one or more contours, along a line defined by an angle and a length.

Applications: the surface is used to create an angled surface, a tapered wall, or cones and cylinders.

Examples:

You can select multiple entities to chain. Mastercam creates a separate draft surface for each individual entity in each chain. A zero value entered in the Angle field produces no tilt and is the equivalent of an extrusion perpendicular to the construction plane.

Extrude Surface

Define the plane by selecting Entities button , and then select from the graphic window two lines that intersect.

Make sure that the resulting arrow will point towards the original chain. Definition: Extrude Surface command creates CAD surfaces over the closed chains. Applications: the surface is used to create an angled surface, a tapered wall, or cones and cylinders.

Note that the different between the draft surface command and the extrude surface command is that the last creates extra surface at the top and bottom of the shape.

Create the extrude surface in the lower right corner. Create

Surface Extrude

Select the chain and then enter the values in the dialog box to match the ones from the finish geometry in the right colummn. (Length = 1.0; Angle = 5 deg.)

Note that changes that you make using the Extruded Surface dialog box affect the surface model only, not the curves from which it was created.


Page-23

Ruled Surfaces

Loft Surfaces

RULED / LOFTED SURFACES Definition: Ruled Surface is a surface generated by connecting straight lines between two or more open or closed contours. When creating a ruled surface with three or more curves defining the boundary, Mastercam creates separate surfaces between each pair of curves rather than one surface with sharp corners and ridges. Applications: any time a surface must be fit between two or more open or closed contours. Example:

Definition: Loft Surface is a surface generated by blending together more than 3 open or closed contours. As a result the surface has rounded edges at the intermediate contours. Applications: any time a surface must be parabolically blended through more than two curves. Note that the system will automatically create a ruled surface through two chains of entities.

Synchroni- zation

Create ruled surfaces with Synchronization. In order to better match the curves or chains of curves, you may want to select your curves using the Sync chaining method (Chaining Options dialog box), which lets you match curves manually or by entity, branch, node, or point. Synch by branch match the curves at the branches.

Tips: In the Chaining dialog box select the Options button and enable Mask on Color. The color mask excludes from chaining all entities except those whose colors match any of the color(s) you select. Note that the chains are green color, while the branches are blue.

Students complete Tutorial 5 toolpaths

The following toolpaths are shown in Tutorial 5: Surface HS - Core Roughing Surface Finish Scallop Surface Rough Pocket with Facing option Surface Finish Pencil Check Holder C-Hook Surface Finish Project

SURFACE HIGH SPEED – CORE ROUGHING Definition: Surface HS Core Roughing toolpaths are designed for machining cores which can be approached from the outside. An important feature of core roughing is that Mastercam can change the machining strategy within the same operation if the part has, for example, a mixture of bosses and cavities. In these cases, Mastercam will cut the cavities inside to out (like an area clearance cutting pass), and machine the bosses from the outside.

Mastercam Mill Level 3 Training Tutorial Page 5-26 to page 5-73 PowerPoint: Lesson 15.ppt


Page-98

Cut Parameters Transitions Linking Parameters

Specific Surface HS Core Roughing Parameters Cut Parameters Step-down value sets a constant Z spacing between cutting passes. Add cuts feature allows you to insert additional cutting passes in areas of your part where the profile is close to flat. Mastercam will add new cuts to maintain the maximum profile stepover, while spacing them each by at least as much as the minimum step-down. Smoothing inserts arcs at corners to create smoother tool motion. The amount of smoothing is constrained by the maximum radius that you enter. XY stepover settings allows you to configure the spacing between the passes at the same Z. Mastercam will use the largest value possible (up to the maximum XY stepover) that does not leave unwanted material between the passes. However, it will not separate the passes by less than the minimum stepover. Transitions Transitions allow you to configure the entry move that the tool will make as it transitions to new Z levels. You can choose to create either a ramp entry, or helical entry move. If the profile is too small to create a helix of this size, Mastercam will create a ramp move instead. Linking Parameters Linking options allow you to configure how Mastercam links air moves when the tool is not in contact with the part. Minimum vertical retract is a vertical retract and constant-Z move at the Part clearance height. Leads fields set the tool moves onto and off of the part at the start and end of each cutting pass. These moves are applied to each pass no matter which cutting pass is selected. Fitting settings allow you to choose how the entry and exit arcs fit to the ends of the cutting passes. Minimize trimming sets the path to retract to be as close to the surface as possible, maintaining a minimum distance from the surface to fit the arc. Max trimming distance parameter limits the amount of trimming applied to non-horizontal passes.


Page-99

Arc Filter/ Tolerance Rough Pocket - Facing

Profile tolerance determines the maximum deviation between the smoothed and unsmoothed toolpaths and is only applied on the outermost cutting pass. Offset tolerance is defined in the same way as the Profile tolerance, but it is applied to all the inner passes.

SURFACE ROUGH POCKET WITH FACING Definition: Surface Rough Pocket Facing automatically detects and creates motion on the flat surfaces within a pocket.

Specific Surface Rough Pocket-Facing Parameters Floor extensions a 2D offset that extends the toolpath off the flat surface. This will allow the tool to start just off the flat floors in open areas of the pocket Floor adjustment an additional Z stock offset, positive or negative can be used Wall clearance additional clearance from wall surfaces in X and Y direction.



Page-100

Finish Pencil toolpath

SURFACE FINISH PENCIL

Definition: Surface Finish Pencil toolpaths can be used as a finish operation to clean leftover materials from corners. The toolpath is generating a trace between the sharp edges of the selected surfaces.

Specific Surface Finish Pencil Parameters Parallel passes

None creates a single pencil toolpath. Number per side allows you to specify the number of passes on each side of the pencil trace. Unlimited allows Mastercam to create an unlimited number of offset passes all the way across the selected drive surface.

Bitangency angle defines the angle between surfaces that can be machine with the pencil toolpath. Over thickness value is added to the cutter radius. It is used when the cutter’s radius is very close or smaller than any fillets in the drive surfaces.



Page-101

Finish Project toolpath

SURFACE FINISH PROJECT Definition: Surface Rough and Finish Project Toolpaths allow you to project curves, points, or another NCI file onto selected surfaces. These toolpaths can closely match the cut motion to the shape of the part and can be used for engraving.

Specific Surface Finish Project Parameters Projection type

NCI allows you to project an existing 2D toolpath (contour or pocket) onto selected surfaces. Curve allow you to project 2D chains of entities (lines, arcs, splines) onto selected surfaces. Mastercam prompts you to select the chains after you exit project parameters. Points allow you to project points onto selected surfaces. Mastercam prompts you to select the chains after you exit project parameters.

Retract between cuts forces a retract move between cuts and for engraving letters (curve projection type) allows the tool to retract between letters. Add depths allow you to add cut depths for the rough project. It is enabled only with projection type NCI.
