Writing Programs
Overview
The MILLPWR G2 allows many features to be used without having to
write a program. For operations that repeat, or complex machining it
is best to write a program. Before writing a program, determine the
work-holding device and the location of Part Zero (the point to which
all movement is referenced). Since absolute positions are defined
from Part Zero, try to select a location that directly corresponds to
dimensions provided on the part print, such as the lower left corner of
the work. Then you can develop a program. The following is a general
approach to programming:
 First, select the unit of measurement (Inch/MM) using the MM key.
This will place the DRO in the required unit of measure, and all
dialogues will use the selection. If the selection is changed after
data has been entered, the MILLPWR
G2 will convert the data to the
new unit of measure.
 The first step in a program selects the tool that is to be used. It’s size
can be entered in either Inch or MM regardless of the unit of
measure selected in the DRO. The Tool dialogue provides fields for
data input for the tool position. This is a tool change position, a
location away from the work area where the axes can return for safe
tool changing. TOOL POSITION will use the unit of measure that has
been selected for the DRO.
 The remaining steps in the program describe the required moves,
single cycles, and Tool changes to complete the machining.
 The next to the last step in the program returns the axes to the Tool
change position and ends the program.
 After writing a program, verify it. Run it to troubleshoot for errors.
Verify that all programmed moves are safe, and accurate to the part
print dimensions.
 Setup the work piece into the intended holding device.
 First run the program in Single-Step Mode to verify that both the
program and the setting of Tool Offsets are correct. Single-Step
Mode allows you to run the program step-by-step. Make any
necessary corrections. Once verified, the program can be run in
Auto Mode.
 When the finished program is ready for production, back it up on a
USB memory device.
If there is an interruption to the power supply, the program
is not lost. The program is periodically saved. Verify that
the most recent steps (prior to the power failure) are in the
program. The fixture zero location is also remembered.
