(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 Fig. 1. 2‚ 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 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. 
The section between division points n and n+1 is compensated smoothly by linear approximation.
