Prediction of Cutting Force in a Circular Peripheral Milling …
The circular peripheral milling process is assumed to be a linear peripheral milling process for a length equal to p (Fig. 1). In the model, this length is considered to be equal to the feed rate per tool rotation t in the x t p Nf R, where R p is the circular workpiece profile radius, f Nis the feed rate per tooth, t
