摘要： A method of and device for correcting a cutting-edge position of a tool installed in a numerically controlled machine. The device includes a CPU which operates a basic processing program, taking a cutting-edge position correction value thereinto, a judging unit for judging whether a temperature of the main spindle table is in a normal condition or an abnormal condition when exchanging the old tool for the new tool, a normal position correcting unit for detecting a movement amount of tool table necessary to bring the cutting-edge of the new tool into contact with a cutting-edge detecting sensor, an abnormal position correcting unit for detecting the movement amount of tool table necessary to bring the cutting-edge of the old tool into contact with the cutting-edge detecting sensor, and cutting ability adjusting unit for memorizing a dimensional change of the work machined as the cutting ability correction value of the tool in the abnormal condition. The normal and abnormal position correcting units memorize a difference between the movement amount including the cutting-edge position correction value on memory at that time and the predetermined standard dimension, as the normal and abnormal cutting-edge position correction value for the new tool, respectively.
