1. AXIS CONTROL
188
Suppose that a workpiece on the spindle (Z1–axis) that moves along the
axis is to be cut with a tool in path 1 and a tool in path 2 simultaneously.
This example superimposes the amount of movement of the Z1–axis on
that of the Z2–axis.

Machining is performed by
a path 1 program.

Z1
Z2
Machining is performed by a path 2 program.
Because the amount of movement of the master axis is added to that of
the slave axis, the resulting speed of the slave axis may become much
larger than a normal speed (such as rapid traverse speed specified in a
parameter). To solve this problem, it is necessary to set feedrates that are
used only during superimposed control. The feedrates and time constants
that are used only during superimposed control include:
S Rapid traverse rate: Parameter No. 8190
S Rapid traverse override F0 rate: parameter No. 8191
S Rapid traverse linear acceleration/deceleration time constant:
Parameter No. 8192
S Maximum cutting feedrate: Parameter No. 8193
(S Manual rapid traverse rate:
Parameter No. 8190 or 1424 whichever is smaller)
