7 Programming with Q Parameters 7.7 Measuring with the 3D Touch Probe During Program Run 7-12 The 3D touch probe can measure positions on a workpiece during program run. Applications: • Measuring differences in the height of cast surfaces • Checking tolerances during machining To activate the touch probe, press the TOUCH PROBE key. You preposition the probe, which then automatically probes the specified position. The coordinate measured for the probe point is stored in a Q parameter. The TNC interrupts the probing process if the probe is not deflected within a certain range (range selected with MP 6130). To program the use of a touch probe: TOUCH PROBE TCH PROBE 0: REF. PLANE PARAMETER NUMBER FOR RESULT? 5 PROBING AXIS/PROBING DIRECTION? +/ X X Y 0 Z ENT POSITION VALUE? ENT 5 ENT ENT +/ 5 Resulting NC blocks: TCH PROBE 0.0 REF. PLANE Q5 X– TCH PROBE 0.1 X+5 Y+0 Z–5 Select the touch probe function. Fig. 7.4: Workpiece dimensions to be measured Enter the number of the Q parameter to which the coordinate is to be assigned (in this example, Q5). Enter the probing axis for the coordinate (in this example, X). Select and confirm the probing direction. Enter all coordinates of the pre-positioning point values, in this example, X = 5 mm, Y = 0, Z = –5 mm. Conclude input. Pre-position the touch probe manually such that it will not collide with the workpiece when it moves toward the programmed position. Y 100 –10 Z L? α? α? X 100 TNC 360
7 Programming with Q Parameters 7.7 Measuring with the 3D Touch Probe During Program Run TNC 360 Example for exercise: Measuring the height of an island on a workpiece Coordinates for pre-positioning the 3D touch probe Touch point 1: X = + 20 mm (Q11) Y = 50 mm (Q12) Z = 10 mm (Q13) Touch point 2: X = + 50 mm (Q21) Y = 10 mm (Q22) Z = 0 mm (Q23) Part program: 0 BEGIN PGM 3600717 MM 1 FN0: Q11 = + 20 2 FN0: Q12 = + 50 3 FN0: Q13 = + 10 4 FN0: Q21 = + 50 5 FN0: Q22 = + 10 6 FN0: Q23 = + 0 7 TOOL CALL 0 Z 8 L Z+100 R0 FMAX M6 .......................................

The Z coordinate probed in the negative direction is stored in Q10 (1st point) 11 L X+Q21 Y+Q22 ................................................. Auxiliary point for second pre-positioning 12 TCH PROBE 0.0 REF.PLANE Q20 Z– 13 TCH PROBE 0.1 X+Q21 Y+Q22 Z+Q23 ............. The Z coordinate probed in the negative direction is stored in Q20 (2nd point) 14 FN2: Q1 = Q20–Q10 .......................................... Measure the height of the island and assign to Q1 15 STOP .................................................................. Q1 can be checked after the program run has been stopped (see page 7-14) 16 L Z+100 R0 FMAX M2 17 END PGM 3600717 MM ....................................
