Slot Milling (Cycle) - HEIDENHAIN ITNC 530 User Manual

SLOT MILLING (Cycle 253)
Use Cycle 253 to completely machine a slot. Depending on the cycle
parameters, the following machining alternatives are available:
Complete machining: Roughing, floor finishing, side finishing
Only roughing
Only floor finishing and side finishing
Only floor finishing
Only side finishing
With an inactive tool table you must always plunge
vertically (Q366=0) because you cannot define a plunging
angle.
Roughing
1 Starting from the left slot arc center, the tool moves in a
reciprocating motion at the plunging angle defined in the tool table
to the first infeed depth. Specify the plunging strategy with
Parameter Q366.
2 The TNC roughs out the slot from the inside out, taking the
finishing allowances (parameter Q368) into account.
3 This process is repeated until the programmed slot depth is
reached.
