Setting Z-axis Datum when Changing Tools
Whenever you encounter a SET TOOL step, MILLPWR will display the DRO screen and let you know
which tool to load. If no tool diameter was programmed in the “Tool Step,” you will be prompted to
provide one.
• Use the MOVE TABLE softkey and arrow keys to
move the tool away from your workpiece.
• Press the move table softkey again to turn off the motors.
• Insert the required tool into the spindle.
• Using the MOVE TABLE feature, position the tool over
the surface of a known depth on your workpiece.
• Press the DATUM softkey.
• Position your tool so that it touches a known surface,
then enter that position into the Z-axis datum.
• Press the USE key.
• Raise the tool and press the GO key to continue the
program.
Drilling Conventions
Peck
“Hole” and “Position/Drill” steps give you the option of programming the quill to
“peck” or pause briefly. Peck cycles are used to break chips and reduce chip buildup
during drilling operations.
You can control how frequently a peck occurs by entering a value in the “Peck” field.
Tool Retract
Using the “Tool Retract” feature, you can program MILLPWR to raise the quill at a speci-
fied distance or frequency. This will allow the tool you’re drilling with to cool.
Dwell
“Dwell” is the length of time (in seconds) that the quill will pause during a tool retract.
If the surface is at datum 0,
use the Z = 0 softkey.
