Touch probe cycles for automatic operation
The control provides numerous touch probe cycles for various
applications:
 Calibrating a touch trigger probe
 Measuring circles, circle segments, angle and position of the C axis
 Misalignment compensation
 Single-point and double-point measurement
 Finding a hole or stud
 Zero point setting in the Z or C axis
 Automatic tool measurement
Touch probe cycles are programmed in DIN PLUS using G codes. Just
like the fixed cycles, also the touch probe cycles use transfer
parameters.
To simplify programming, the control shows a graphic during cycle
definition. The appropriate input parameters are displayed in the help
graphic (see figure at right).
The touch probe cycles save status information and measuring results
in the variable #i99. Depending on the input parameters in the touch
probe cycle you can interrogate the following values:
Result #i99 Meaning
< 999997 Measuring result
999999 Touch probe not deflected
-999999 Invalid measuring axis programmed
999998 Maximum deviation WE exceeded
999997 Maximum compensation value E exceeded
