8025/8030 CNC PROGRAMMING MANUAL 89
6.29.4. G75. PROBING
G75 prepares the CNC to receive the signals coming from a measuring probe.
Format:
N4 G75 (V+/-4.3) (W+/-4.3) X+/-4.3 Y+/-4.3 Z+/-4.3
The axes will move until the probe signal is received. The CNC will then consider the block
to be completed and the real position of the axes will be stored as theoretical position.
Neither the feedrate will be changed by turning the FEEDRATE knob (frozen at 100%) nor
the movement of the axes will be displayed until the probe signal is received.
If the axes arrive in position before the probe signal is received, the CNC will act as follows:
If machine parameter "P621(6)=0", the CNC interrupts the program execution and it issues
error 65. But, if "P621(6)=1", the CNC will consider the block completed and it will go on
to execute the next block.
After executing this block, the values of the different axes can be allocated to the desired
parameters. The combination of this feature with mathematical operations with parameters
permits creating special subroutines to measure parts or tools.
G75 implies G01 i.e. the CNC assumes function G01 and G40 after a G75 block.
Atention:
This CNC allows manually measuring the length of the tools with a probe.
