In the machining process, cutting force is a physical quantity well reflecting the process itself. Measured cutting force is used to identify the tool wear, surface roughness, chip formation, chatter stability and dynamic cutter runout problems. The cutting force linearity is used to measure and control the irregular cutting phenomena and machining process. We applied force-adaptive cutting control technology to evaluate chatter and real-time compensation for dynamic cutter runout. We proposed the concept of force-adaptive cutting control in the angle domain based upon proportional-integral control to control chip-load variation in machining. The micropositioning control of cutting tool or workpiece positioning using a low-friction sliding table and piezoelectric actuator changed the chip-load variation. Our results are expected to provide invaluable information in precision machining technology.
