Summary:The cutting force closely reflects the physics of material removal processes, therefore, much attention has been paid to its measurement. Various sensors have been examined and their feasibilities have been analyzed by many researchers. This study proposes an indirect cutting force estimation method with spindle loads acquired from computer numerical control (CNC). The characteristic of a spindle motor is carefully investigated and the tangential cutting forces are estimated based on spindle loads. Experiment results show that estimation errors depend on the spindle rotation speed and the magnitude of the cutting force. The proposed method can be practically applied to the field, where the magnitude of cutting force is needed but sensors cannot be attached. KCI Citation Count: 1
