<P>PROBLEM TO BE SOLVED: To provide a control method with a small amount of calculation capable of performing a common calculation in various types of machines. <P>SOLUTION: For a machine equipped with a main spindle head 2 and a table 3 which are movable relatively to each other, a method for controlling movement of the main spindle head 2 and the table 3 by using a plurality of command values to which compensation values for compensating geometric errors are applied has: a first index which indicates the presence or absence of a rotation axis on the main spindle head 2 side or a linkage order when it is present; and a second index which indicates the presence or absence of the rotation axis on the table 3 side or a linkage order when it is present. A matrix arithmetic of the command value in a coordinate system of the table 3 is performed according to the presence or absence of the rotation axis or the linkage order indicated by the first index to obtain a first vector, a matrix arithmetic of a reference vector of the main spindle head 2 is performed according to the presence or absence of the rotation axis or the linkage order indicated by the second index to obtain a second vector, and the first and second vectors are summed up. <P>COPYRIGHT: (C)2013,JPO&INPIT |
