19.9.3 Example of Controlled Axis Configuration
- Gear grinder
Spindle : EGB master axis: Tool axis
First axis : X
Second axis : Y
Third axis : C-axis (EGB slave axis: Workpiece axis)
Fourth axis : C-axis (EGB dummy axis: Not usable as an ordinary
controlled axis)
Fifth axis : V-axis (EGB slave axis: Dressing axis)
Sixth axis : V-axis (EGB dummy axis: Not usable as an ordinary
controlled axis)
NOTE
With a sampling frequency of 1 ms, a feedback pulse
signal is read from the master axis, the number of
synchronization pulses for the slave axis is calculated
from the synchronization factor K, and the calculated
value is used for slave axis position control.
