- In simultaneous 3 axes control, the feed rate is calculated the same
way as in 2 axes control.
Example
- Linear interpolation
Fig.4.3 (a) Linear interpolation
- Feedrate for the rotation axis

G91 G01 X20.0 C40.0 F300.0 G
This changes the unit of the C axis from 40.0 deg to
40mm with metric input.
The time required for distribution is calculated as
