Sales OnlineThe 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 ...

Sales OnlineWhen choosing the right parameters to run, most people focus on the speed which relates to the machine RPM. This is a mistake! Focus on on the proper feed per tooth (FPT), and then adjust the speed. Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.
