10.3.7 Reference point approach: G74
Functionality
The reference point can be approached in the NC program with G74. Richtung und
Geschwindigkeit jeder Achse sind in Maschinendaten hinterlegt.
G74 erfordert einen eigenen Satz und wirkt satzweise. The machine axis identifier must be
programmed!
In the block after G74, the previous G command of the "Interpolation type" group (G0,
G1,G2, ...) is active again.
Programming example
N10 G74 X1=0 Z1=0
Remark: The programmed position values for X1, Z1 (here = 0) are ignored, but must still be
written.
10.3.8 Measuring with touch-trigger probe: MEAS, MEAW
Functionality
The function is available for SINUMERIK 802D sl plus and pro.
If the instruction MEAS=... or MEAW=... is in a block with traversing movements of axes, the
positions of the traversed axes for the switching flank of a connected measuring probe are
registered and stored. The measurement result can be read in the program for each axis.
For MEAS, the movement of the axes is halted when the selected switching flank of the
probe appears and the remaining distance to go is deleted.
Programming
MEAS=1 G1 X... Z... F... ; Measuring with rising edge of the probe, clearing the
distance to go
MEAS=-1 G1 X... Z... F... ; Measuring with falling edge of the probe, clearing the
distance to go
MEAW=1 G1 X... Z... F... ; Measuring with rising edge of the probe, without
clearing the distance to go
MEAW=-1 G1 X... Z... F... ; Measuring with falling edge of the probe, without
clearing the distance to go
