4. MACHINING DEFINITION
(MENU NO. 4)
SLANTED SURFACE MACHINING
785
(1)Making holes and performing patterned machining on a slanted
surface
a) Safety–first mode (bit 1 of system parameter No. 309 = 0)
When approaching in this mode, the tool moves from the
tool–change position to the safe plane (machining figure top
surface + safety height (SH) + clearance (C1) apart) at the rapid
traverse rate simultaneously with respect to the three axes (X, Y, Z).
Then it starts cutting at the cutting feedrate. Between figures, the
tool moves to the safe plane, then to the next figure at the rapid
traverse rate. When escaping, the tool moves to the safe plane at
the rapid traverse rate, then returns to the toolchange position by
reference position return or rapid traverse.

b) Efficiency–first mode (bit 1 of system parameter No. 309 = 1)
When approaching in this mode, the tool moves from the
tool–change position to the safe plane (machining figure top
surface + safety height (SH) + clearance C1 apart) at the rapid
traverse rate simultaneously with respect to the three axes (X, Y, Z),
then to a position clearance C1 apart from the top surface of the
machining figure at the rapid traverse rate. After this, it starts
cutting at the cutting feedrate. Between figures within one C–axis
phase, the tool moves to a position clearance C1 apart from the top
surface of the machining figure, then to the next figure, at the rapid
traverse rate. Between Caxis phases, the tool passes through a
position clearance C1 apart from the top surface of the machining
figure to the safe plane, then to the next figure, at the rapid traverse
rate. When escaping, the tool moves through a position clearance
C1 apart from the top surface of the machining figure to the safe
plane at the rapid traverse rate, then to the toolchange position by
reference position return or rapid traverse.
