Provided is an apparatus and a method thereof which can detect a displacement amount of a cutting tool with respect to a workpiece with high accuracy and can correct a processing position with high accuracy. Accordingly, a turret gaugeis comprised of an invar bodyand a gauge main bodywith a different thermal expansion coefficient. A point A of the gauge main bodyand a leading edgeA of the invar body are imaged in a state of viewing the whole thereof at a time of an initialization and a calibration cycle (CS), and a temperature of the gauge main bodyis detected by comparing each image data. Furthermore, the length between the point A and a point B of the gauge main bodyat the time of the CS is obtained based on the image data. The actual length is compared with a theoretical length between the point A and the point B at a temperature of the gauge main bodyat the time of the CS, and consideration is given to the comparison. Therefore, a heat displacement amount of a ball screw can be accurately detected, the displacement of a processing position of a cutting tool can be corrected with high accuracy, and processing accuracy of a workpiece can be improved.
