2.1. Surface grinding of silicon wafers Fig. 2 illustrates the surface grinding process. Grinding wheels are resin-bond diamond cup wheels. The workpiece (wafer) is held by the porous ceramic chuck using vacuum. The axis of rotation for the grinding wheel is offset a distance of the wheel radius relative to the axis of rotation for the wafer.

In this work, a novel algorithm was proposed to optimize the wheel's location and orientation for the flute-grinding to achieve higher accuracy and efficiency. Based on the geometrical constraint that the grinding wheel should always intersect with the bar-stock while grinding the flutes, the grinding wheel and bar-stock were simplified as an ellipse and circle via projecting in the cross ...

GEAR GRINDING Grinding wheels are used to correct or modify the profile of gear teeth after heat treatment. The machine and gear type determine the shape of the grinding wheel. Continuous gear generation, profile grinding, bevel gear grinding, and power honing are the most common grinding processes in gear grinding.

In the micro-grinding process, owing to the size effect, the effects of material microstructure on the grinding force are more significant through the variation of material flow stress. Currently, the variation of material flow stress resulting from the change of crystallographic orientation during the micro-grinding has not been well examined.

In practice, the flutes of end mills are ground using CNC grinding machines via controlling the grinding wheel's position and orientation to guarantee the designed flute parameters including rake angle, flute angle, helix angle, and core radius. However, for the previous researches, the designed flute profile was ground via building a specific grinding wheel with a free-form profile using ...
