Abstract: PURPOSE:To improve the accuracy of measurement, by determining beforehand relational expressions each showing an amount of error caused by warping in the vertical direction of a cross rail, by measuring the temperature of each part of the cross rail, and by substituting measured values thus obtained for values in each of said relational expressions for compensation. CONSTITUTION:When temperatures detected by temperature sensors S3 and S4 are denoted by t3 and t4 respectively, temperatures detected by temperature sensors S5 and S6 by t5 and t6 and the amount of projection of the contact maker 1a of a touch sensor 1 in the direction of Z co-ordinates to a scale 2 by Z0, an amount l2 of error caused by warping in the longitudinal direction of a cross rail and an amount DELTAl3 of error caused by warping in the vertical direction of the cross rail can be expressed by expressions I and II respectively. Then, by compensating a measured size value with the amounts DELTAl1, DELTAl2 and DELTAl3 of errors thus found, according to an expression III, a true size l' can be found. The accuracy of measurement is improved since errors in measurement accompanying the thermal deformation of a machine are taken into consideration in this case.
