ABSTRACT:
A digitize control apparatus having a measuring function of the present invention determines a correct contact point between a stylus and a model on the basis of the displacement vector of a stylus obtained by a scanning head and a position vector indicating a machine coordinate value obtained by a position detecting apparatus, and therefore the influence of friction generated between a stylus and a model can be removed, thereby reducing error in the measurements.
