The TNC then requests the data for the selected cycle:
SETUP CLEARANCE?
Enter setup clearance, for example –2 mm.
TOTAL HOLE DEPTH?
Enter total hole depth, for example –30 mm.
THREAD PITCH?
Enter thread pitch, for example +0.75 mm.
Resulting NC block: 17.0 RIGID TAPPING
17.1 SET UP –2
17.2 DEPTH –30
17.3 PITCH +0.75
Cycle call
The following cycles become effective immediately upon being defined in
the part program:
• Coordinate transformation cycles
• Dwell time
• The SL cycle CONTOUR
All other cycles must be called separately. Further information on cycle
calls is provided in the descriptions of the individual cycles.
If the cycle is to be programmed after the block in which it was called up,
program the cycle call
• with CYCL CALL
MISCELLANEOUS FUNCTION
Cycle call with miscellaneous function M3.
• with the miscellaneous function M99.
If the cycle is to be run after every positioning block, it must be called with
the miscellaneous function M89 (depending on the machine parameters).
M89 is cancelled through
• M99
• CYCL CALL
• a new cycle definition
Prerequisites:
The following data must be programmed before a cycle call:
• BLK FORM for graphic display
• Tool call
• Positioning block for starting position X, Y
• Positioning block for starting position Z (setup clearance)
• Direction of rotation of the spindle (miscellaneous functions M3/M4)
• Cycle definition (CYCL DEF).
