[3] The checking of error waveforms
Check the error waveforms of the time constant to be set to confirm that the synchronous errors are less than
or equal to the base value.
Disable machine end compensation such as backlash compensation before checking.
Base value
-
The base value of synchronous errors is 8.8° or less during M6 and PIT1 machining.
(The conventional base value of 100 pulses or less is based on 4096 pulses per rotation, therefore
100 [pulse]/4096 [pulse] × 360 [°]
≒
8.8 [°])
-
As shown in the figure below, a synchronous error may become larger due to lost motion of a servo
axis etc. when starting tapping or during velocity reversal at the hole bottom. At the start, the work is
not within cutting range so it will not be affected. When this error is large, adjust the servo axes with
lost motion compensation etc.
-
When torque saturation is released, synchronous errors may become larger. There is no problem if
the synchronous error is the same or smaller than the base value. If the error is large, it can be
improved by increasing the time constant or lowering the synchronous tapping position gain of the
spindle.
