Interpolation control

The interpolation function controls two or more axes alternately or simultaneously. Linear
interpolation and circular interpolation are usually offered.

End point
- Linear interpolation controls two or
more axes so that the start point and
the end point (target position) are
connected in the shortest way.
- In this case, the locus is linear.
- Models applicable to 2-axis linear
