Calculate the press force required to produce given component. sheet thickness = 1 mm. Shearing strength = 350 N/mm^2.

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 milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters ...
