...Qingzhao Li; Soichi Ibaraki; Wei Wang The five-axis machining of a free-form surface often contains the reversal of a rotary axis’ rotation direction with linear axis synchronized with it. This paper proposes a new machining test to quantitatively evaluate the influence of the reversal of rotation...

... in micro-milling, but also in macro-milling, there is also an obvious size effect, especially in medium- and high-speed milling, which is frequently ignored. In this paper, the milling force prediction model for five-axis machining of a freeform surface with a ball-end mill considering the mesoscopic size...

...Dong He; Yamin Li; Zhaoyu Li; Kai Tang A critical task in multi-pass process planning for the five-axis machining of complicated parts is to determine the intermediate surfaces for rough machining. Traditionally, the intermediate surfaces are simply parallel Z-level planes, and the machining...

... and interpolation algorithm for five-axis machine tools. The transition corners of the tool tip position and tool orientation are analytically smoothed in the workpiece coordinate system (WCS) and the machine coordinate system (MCS) by C 3 continuous PH splines, respectively. The maximum deviation errors...

... actuator reversals, which induce unexpected vibration. The efficiency is also influenced. When the tool passes through the corner with a large variation, the rotary and tilt table of the five-axis machine undergoes large motion steps, which may exceed the motion capacity of the machine tool. In our...
