C–AXIS FAPT FUNCTION
1. PART FIGURE DEFINITION
1 Be careful not to make the setting shown in Fig.1.5(b),
where a C–axis machining figure is on a plane which is not
machined. The system does not regard such setting as
If feed mode 2 is selected, the tool may strike against the
workpiece when holes b, c, and d are cut.
2 If the part figure definitions contain a C–axis part figure for
which a machining plane is entered, the process sequence
of machining definition must be determined carefully. In
Fig. 1.5 (a), for example, drilling must be specified after
milling. Even if drilling is programmed before milling, the
system does not regard this sequence as being illegal.
3 Whenever a machining method (2, 3) including pecking is
selected, and feed mode 1 is used for a C–axis drilling
process, pecking starts from the approach point, regardless
of the value set for the machining plane.
