✦ Synopsis

A new analytical cutting force model is proposed for micro-end-milling operations. The model calculates the chip thickness by considering the trajectory of the tool tip while the tool rotates and moves ahead continuously. The proposed approach allows the calculation of the cutting forces to be done accurately in typical micro-end-milling operations with very aggressively selected feed per tooth to tool radius (f t /r) ratio. The difference of the simulated cutting forces between the proposed and conventional models can be experienced when f t /r is larger than 0.1. The estimated cutting force profile of the proposed model had good agreement with the experimental data.

The micro-end-milling operations typically have aggressive feed per tooth per radius compared to conventional milling operations thereby resulting in different forces and cutting force constants. In addition, the trochoidal nature of the tool path could also result in different force constants. An e

This paper presents a model for the prediction of cutting forces in the ball-end milling process. The steps used in developing the force model are based on the mechanistic principles of metal cutting. The cutting forces are calculated on the basis of the engaged cut geometry, the undeformed chip thi
