SETUP CLEARANCE?

Enter setup clearance, e.g. +2 mm.

TOTAL HOLE DEPTH?

Enter total hole depth, e.g. –30 mm.

Cycle call

The following cycles become effective automatically by being defined in
the part program:

• coordinate transformation cycles,
• the dwell time cycle, and
• the SL cycles which determine the contour and the global parameters.

The remaining cycles must be called-up separately. Further information on
cycle call is provided in the descriptions of the individual cycles.

If the cycle is to be executed 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 miscellaneous function M99.

If the cycle is to be executed after every positioning block, the cycle must
be called-up with miscellaneous function M89 (depending on machine
parameter MP7440).

The effect of M89 is cancelled with
• M99
• CYCL CALL
• CYCL DEF.

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 (machining level) with radius compensation R0
• Positioning block for starting position Z (tool axis, safety distance)
• Direction of rotation of the spindle (additional functions M3/M4; exception: cycle 18)
• Cycle definition (CYCLE DEF).
