2. Inspection – Check the cutting edge
Inspect the tool; if necessary, replace it.
Conclude the inspection process. The CNC PILOT
loads the return motion program (_SERVICE).
The “Tool compensation” dialog box appears. Enter the tool
compensation.
If you are using a new cutting edge, modify the tool compensation so
that the tool—when returning—comes to a stop before the point of
interruption.
If necessary, activate the spindle.
3. Inspection – Return the tool to the work
At the beginning of the returning program, the control asks the two
questions “Scrambled takeoff on restart?” and “Start from/before
interruption point.” Your answers determine the return motion
program as follows:
„ Scramble takeoff = yes (see 3.1 Return the tool and “scrambled
takeoff”)
„ Move to point of interruption: The return motion program
positions the tool at rapid traverse to the interruption point and
continues the program without stopping.
„ Move to before point of interruption: The return motion program
positions the tool in rapid traverse to a position before the
interruption point and continues the program without stopping.
„ Scramble takeoff = no (see 3.2 Return the tool and stop)
„ Move to point of interruption: The return motion program
positions the tool to the interruption point and stops the program.
„ Move to before point of interruption: The return motion program
moves the tool to a position before the interruption point and
stops the program.
“Scrambled takeoff = yes” is usually used when the cutting edge is
not exchanged.
