MACHINING PROGRAM 4
4-15
4-4 Machining Motion
This section explains “Machining motion”.
This section describes “program composition”, “parameter setting” and “sample program” for
each machining method.
4-4-1 Turning program
This section explains turning operation programs.
1. Turn–drilling operation
Turn-drilling needs to use a G97 (Constant surface speed control OFF) as it cuts at the spindle
center.
