1.3.6 Interpolated Straightness Compensation
Overview
This function divides the compensation data established using the
compensation data for straightness compensation at 128 points among
compensation points and outputs the resulting data.
Explanation
- Compensation system
In the compensation system for straightness compensation at 128
points, for each interval between compensation points along the
moving axis, the straightness compensation for the compensation
points is output to the compensation axis, as shown in Fig. 1.3.6 (a).

In the system for interpolated straightness compensation, the
straightness compensation for each pair of compensation points on the
moving axis is divided and output to the compensation axis, as shown
in Fig. 1.3.6 (b).
