Example: Measuring the height of an island on a workpiece
Program sequence
„ Store coordinates for pre-positioning the
electrode in Q parameters
„ Probe probe point 1
„
Probe probe point 2
„ Determine the height from the difference in Z
values
0 BEGIN PGM PROBE MM
1 FN 0: Q11 = +20 Parameter coordinates for probe point 1 in the X axis
2 FN 0: Q12 = +50 Parameter coordinates for probe point 1 in the Y axis
3 FN 0: Q13 = +10 Parameter coordinates for probe point 1 in the Z axis
4 FN 0: Q21 = +50 Parameter coordinates for probe point 2 in the X axis
5 FN 0: Q22 = +10 Parameter coordinates for probe point 2 in the Y axis
6 FN 0: Q23 = +0 Parameter coordinates for probe point 2 in the Z axis
7 TOOL CALL 0 Z Insert probing electrode
8 L Z+100 R0 F MAX M Retract to safety clearance
9 TCH PROBE 0.0 REF. PLANE Q10 Z– Assign the Z coordinate probed in the negative direction to Q10
10 TCH PROBE 0.1 X+Q11 Y+Q12 Z+Q13 Touch probe is valid for point 1
11 L X+Q21 Y+Q22 Auxiliary point for second pre-positioning
12 TCH PROBE 0.0 REF. PLANE Q20 Z– Assign the Z coordinate probed in the negative direction to Q20
13 TCH PROBE 0.1 X+Q21 Y+Q22 Z+Q23 Touch probe is valid for point 2
14 FN2: Q1 = Q10–Q20 Measure the height of the island and assign to Q1
15 STOP Q1 can be checked after program run has stopped
16 L Z+100 R0 F MAX M2 Retract probing electrode and end program
