Abstract
A profile data compensating method comprises a step of generating effective profile data by operating a machine tool under a non-load condition in accordance with theoretical profile data, a step of generating first error profile data representing error components of a control system, a step of generating first compensated profile data based upon the first error profile data, a step of generating measured profile data by measuring the shape of the workpiece machined in accordance with the first compensated profile data, a step of generating second error profile data representing error components of a mechanical system, and a step of generating second compensated profile data based upon the first and second error profile data.
