4.7 Measurements with touch trigger probe (MEAS, MEAW)
4.7
Function
The "Measure with touch-trigger probe" is used to approach actual positions on the
workpiece. On the probe's switching edge, the positions for all axes programmed in the
measurement block are measured and written to the appropriate memory cell for each axis.
Programming measurement blocks
The following two commands are available for programming measurement blocks:
● MEAS
● MEAW
MEAS and MEAW are non-modal; they are programmed together with motion operations.
The feedrates and interpolation types (G0, G1, etc.), as well as the number of axes, must be
selected as appropriate for the measuring task at hand.
292
The MEAS command is used to delete the distance-to-go between the actual and setpoint
positions.
The MEAW command is used in the case of measuring tasks where the programmed
position always needs to be approached.
