Testing a program
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
The machining stops after every machine block (also in cycles)
Precondition
A program must be selected for execution in "AUTO" or "MDA" mode.
Procedure
1.
Press the "Prog. ctrl." softkey and select the desired variant in the
"SBL" field.
2.
Press the <SINGLE BLOCK> key.
3.
Press the <CYCLE START> key.
Depending on the execution variant, the first block will be executed.
Then the machining stops.
In the channel status line, the text “Stop: Block in single block ended"
appears.
4.
Press the <CYCLE START> key.
Depending on the mode, the program will continue executing until the
next stop.
