ABSTRACT:
A numerical control method for controlling various kinds of machine tools by correcting for thermal displacement. Data relative to thermal displacement, thermal displacement sampling time, and processing cycle time is stored in memory. Before each process, the shift of an absolute position of a machine origin is measured to provide an initial value. The machine tool is energized and thermal displacement data is gathered according to a sampling time. The sampling time is varied according to the degree of thermal displacement. Processing is performed on the data to correct for the thermal displacement of the machine tool.
