10.3.7
Reference point approach: G74
Functionality
The reference point can be approached in the NC program with G74. The direction and
speed of each axis are stored in machine data.
G74 requires a separate block and is non-modal. 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 Y1=0 Z1=0
Note
The programmed position values for X1, Y1, Z1 (any value, 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 edge of a connected measuring probe are
registered and stored. The measurement result can be read for each axis in the program.
For MEAS, the movement of the axes is halted when the selected switching edge of the
probe appears and the remaining distance to go is deleted.
Programming
MEAS=1
G1 X... Y... Z... F... ; Measuring with rising edge of the probe, clearing the
distance to go
MEAS=-1
G1 X... Y... Z... F... ; Measuring with falling edge of the probe, clearing the
distance to go
