Description

This paper clarifies the geometric generating mechanism of chip and machined surface in consideration of the tool orientation in ball-nosed end milling. Firstly the cutting cross section area Ag is proposed as the index of cutting state. lt is one when the cutting edge generates the designed surface in the bottom. lt changes according to the tool orientation, and affects the machining accuracy. Secondly the characteristic related with the tool orientation in several machining, for example contour cutting and scanning cutting, has been clarified. Thirdly there are pointed out the geometric difference of cutting mechanism between ball-nosed end milling and the other end milling.
