In this paper, the ball-end milling process has been studied and cutting force profiles abtained by cutting test have been analyzed for adaptive cutting conditions in CNC machining.
The results were sumarized as follows: (1) Ball-end milling operations have been classified into down milling, up milling, and down/up mixed milling according to some cutting characteristics. (2) For each type of ball-end milling operation, cutter deflection directions have been predicted. (3) Factors affecting cutting force profile and cutting force magnitude have been studied, and an experimental cutting force model has been proposed. (4) An approach to utilizing the proposed cutting force model in adaptive feedrate control is presented in this study.
