Homing The Mill
Homing means to move the spindle or cross slide to a fixed known position on the machine. Homing commands perform two functions:
1. To check against a specified coordinate for calibration loss.
2. To provide for quick machine set up when the part location does not vary.

Help Functions
The help function is easy to use and full of information. The four ways to access help are.
•Selecting the help icon in the Standard tool bar•Selecting help from the main menu•Select the Context Help icon in the Standard tool bar
Context Help allows you to pick on an icon or area of the program interface to get help on that item.
•Selecting the Help button in some dialog boxes
This is similar to context help. It only provides help on the
elements of the current dialog box.

CNC Milling Machine Axis
The Milling machine moves along three Axis - X, Y and Z. When programmed the mill moves to coordinates along the three axis. The origin is the point at which the three axis meet. The graphic shows the orientation of these axis.

Tool LibrarySetting up the tool library properly is a critical step. Once the tool library is setup, however, it does not need to be changed unless a new tool is loaded into a an existing tool holder. During setup the tool is defined by its geometry, size, number of teeth and relative length (Height Offset).
![Page 38: ProLIGHT 1000 Control Software](https://reader035.vdocuments.us/reader035/viewer/2022062217/56815949550346895dc6858d/html5/thumbnails/38.jpg)
Tool LibrarySome of the information in the tool library is simply used when verifying programs. For instance, the NC program only directs the center of the tool so the verify program needs to know the diameter of each tool to show how much material is removed. The tool offsets and tool numbers, however, are very important when running programs with multiple tools. Each tool must be defined with a Tool Height Offset.
![Page 39: ProLIGHT 1000 Control Software](https://reader035.vdocuments.us/reader035/viewer/2022062217/56815949550346895dc6858d/html5/thumbnails/39.jpg)
Tool Setup
The first step in setting up a tool library is to home the machine. The homing process send the mill to a known position along all three axis. The machine can be homed by:
•Selecting Setup in the menu bar and then “Set/Check Home”
•Holding the “Control” key and typing “H”
•Right Clicking on the Jog Control Panel and selecting “Set/Check Home”
![Page 40: ProLIGHT 1000 Control Software](https://reader035.vdocuments.us/reader035/viewer/2022062217/56815949550346895dc6858d/html5/thumbnails/40.jpg)
Tool Height Offsets
Tool Height offset
Where does the mill spindle go
when it is directed to a height of .5?
When a tool offset is established the
control program calculates its Height
move using the offset

Continue setting up as many tools as necessary in the library. Any time that a tool is removed from the tool holder (not the spindle) the height offset must be
reset. Now lets take a closer look at some more options in the tool library.
