According to formula (6), as the spindle speed increases, the grinding force increases, thus improving the grinding efficiency. However, Hu 11 mentioned that there is an upper limit of spindle speed when both feed rate and material type are fixed, because the production capacity of the mill will tend to be stable, and further increasing theThe grinding of superhard materials poses an important challenge to manufacturing industry, due to the increased wear and the high possibility of fracture of both the wheel and workpiece material.

In conventional grinding (CG), camshafts with wide profiles suffer from poor quality and low efficiency because the large contact area between the grinding wheel and camshaft profile limits the diffusion of grinding temperature, leading to burning defects. Swing grinding (SG) can mitigate these problems as it involves a reciprocating motion High-speed rail grinding is a unique passive grinding maintenance strategy that differs from conventional grinding techniques. Its grinding behavior is dependent on the relative motion between the grinding wheel and rail; hence, it possesses great speed and efficiency.

Abstract. Grinding force is an important parameter that affects the productivity and quality of industrial products. The very high negative rake angles of the grits play an important role in the material removal mechanism resulting in the formation of a stagnant area ahead of the grits called the dead metal zone (DMZ).
