ABSTRACT
The present chapter shows that there is basically a two-way interaction between the surface and the manufacturing process. The first interaction is concerned with the nature of the geometric characteristics produced on the surface by the manufacturing process. The other interaction concerns ways in which the surface roughness and form can be used to detect changes in the process and also in some cases the machine tool. Although single-point machining is often used to remove enough material to get the workpiece down to nominal size, it can be used as a finishing process. There are a number of factors that can influence the roughness and introduce extra factors into the evaluation; one is fracture roughness and another is built-up edge on the tool. Milling processes are many and varied and as a result the cutters used and their impression on the surface can be complex.
