Error correction coefficients are applied to each cell of a grid that
covers the measuring area to compensate for encoder and ma-
chine travel variations.
The cells of a standard grid are measured at each corner. The mea-
sured values are compared to the nominal values of the standard
to generate correction coefficients for each cell of the grid. The
correction coefficients are then used to provide error compensa-
tion for the entire measuring area.
The 5 X 4 grid in the following example contains 12 cells. Each
cell corner is an X,Y position for data entry starting in the lower
left corner at 1,1. The lower left data entry position 1,1 corre-
sponds to the datum for the grid (0,0).
The offset from the Machine zero to the standard grid’s datum
must also be entered as data.
