1. The chamfer (C) is cue in cut in one pass.
2. For the method of calculating the path of the chamfering tool, refer Side Preparation (ZS01) (3) (d).
e) When the machining operation (B) is a hole machining or hole (peck) operation.
NOTE 1 Which of hole machining and hole (peck) is to be performed is decided automatically, as follows:
Cutting condition file (No. 470) x Allowance (V) – Bottom finish allowance (Y)
No. 470: Maximum depth of cut for hole machining
If the above expression is true, hole (peck) machining is assumed. Otherwise, hole machining
is assumed.
NOTE 2 For an explanation of the machining operation, refer to ”(3) Operation description” of ”Drilling
(ZH01)” and ”Peck drilling (ZH02).”
NOTE 3 In canned cycles, the following G codes are output.
