Cutting speed and feed determines the surface finish, power requirements, and material removal rate. The primary factor in choosing feed and speed is the material to be cut. However, one should also consider material of the tool, rigidity of the workpiece, size and condition of the lathe, and depth of cut.

The size of motor provided on a modern grinding machine reflects the high power requirement of the grinding process. One theory put forward to explain the rise in U s which accompanies a fall in chip thickness is that the tangential force on the wheel contains a fairly large element of friction due to the rubbing of grits on the workpiece. The ...
