文摘

The high temperature and grinding force in grind hardening induce workpiece distortion that increases the magnitude of grinding to make the workpiece concave. The workpiece distortion also affects the grinding force, grinding heat flux, and grind-hardening depth distribution. The paper uses FE thermo-mechanical coupling model to simulate the thermal distortion in plane grind-hardening. Workpiece distortion, stress, and strain at different moments are calculated out and analyzed for different workpiece sizes. The calculated workpiece distortion is verified through the measured workpiece contour and the hardening layer distribution by experiment.
