The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.

A new processing method, ultrasonic vibration assisted micro end grinding (UAMEG), is proposed to improve micro grinding technology, aiming at machining of brittle-rigid material micro components. Trajectories of adjacent two abrasive were modeled and simulated to perform kinematic investigation and mechanism analysis. The critical condition of regular high-frequency abrasive-workpiece ...
