Executing a trail program run
When testing a program, the system can interrupt the machining of the workpiece after each
program block, which triggers a movement or auxiliary function on the machine. In this way,
you can control the machining result block-by-block during the initial execution of a program
on the machine.
Note
Settings for the automatic mode
Rapid traverse reduction and dry run feed rate are available to run
-in or to test a program.
Move by single block
In "Program control" you may select from among several types of block processing:
SB mode
Scope
SB1 Single block, coarse
The machining stops after every machine block (except for cycles)
SB2 Data block The machining stops after every block, i.e. also for data blocks (except
for cycles)
SB3 Single block, fine
