5.4 SLOT MILLING (Cycle 253,
DIN/ISO: G253)
Cycle run
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
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 (parameters Q368 and Q369) into account.
3 This process is repeated until the slot depth is reached.
Finishing
4 Inasmuch as finishing allowances are defined, the TNC then
finishes the slot walls, in multiple infeeds if so specified. The slot
side is approached tangentially in the right slot arc.
5 Then the TNC finishes the floor of the slot from the inside out. The
slot floor is approached tangentially.

Questions and answers
Can I change the approach direction when cycle def a stud to avoid obstruction to the right
The provided context does not explicitly mention changing the approach direction to avoid obstruction. However, it describes selecting different axis configurations using the MOD function in the Programming and Editing mode. If modifying the axis configuration allows for adjusting the approach direction, it may be possible. Otherwise, specific cycle parameters should be checked in the programming manual.
