ABSTRACT

A method includes: installing a square calibration master on a table, and
measuring each of measurement surfaces A, B, and C of the square calibration
master by a position measurement sensor attached to a main spindle;
calculating a first squareness between the measurement surfaces A and B;
calculating a second squareness between the measurement surfaces A and C;
calculating a difference between the first squareness and the second
squareness; comparing the difference with a preliminarily set difference
threshold value; calculating an average value of the first squareness and the
second squareness when the difference is equal to or less than the difference
threshold value, and calculating a corrected squareness based on an angular
deviation and the first squareness or the second squareness when the
difference exceeds the difference threshold value; and setting the
compensation parameter based on the average value or the corrected squareness.
