(2) Memorized relative position compensation
This method‚ according to the parameters specified in advance‚ compensates the relative position error
between two orthogonal axes caused by deflection of the moving stand.
For this‚ as shown in the following figure‚ specify the compensation amount in the compensation axis
direction in the division points obtained by equally dividing the machine coordinates of the base axis.
The section between division points n and n+1 is compensated smoothly by linear approximation.
The base axis is one of the two orthogonal axes to which relative position compensation applies. This
axis is used as the criterion for relative-error measurement. The compensation axis is the coordinate axis
that is orthogonal to the base axis. The compensation is actually made for this coordinate axis.
