13.13 Spindle Oscillation

13.13.1 Outline

This function reciprocates (oscillates) the spindle at the specified amplitude and frequency.

13.13.2 Detailed Description

Spindle oscillation starts when the spindle oscillation command signal (Y18C8) is turned ON. The spindle decelerates and
stops when the spindle oscillation command signal is turned OFF.
The spindle oscillation ON signal (X18C8) is turned ON while the spindle is oscillating.

Spindle position
The spindle oscillates in accordance with the spindle oscillation amplitude and spindle oscillation configured to the R
registers.

The position of progression in terms of amplitude in the forward di-
rection from the oscillation command position is used as the mid-
way point. The spindle accelerates and decelerates at the rate of
speed determined by the amplitude and frequency to move to the
midway point and then return to the oscillating command position
by accelerating and decelerating at the same rate of speed.
This operation repeats to cause the spindle to oscillate.
