Optimization of tool axis vector for mirror milling of thin-walled parts based on kinematic constraints

In mirror milling of thin-walled parts, the machining path and change in tool axis vector will affect surface quality workpiece efficiency. Reasonable planning can avoid occurrence overcutting undercutting prevent a collision between damage spindle. At same time, rapid also quality, so optimization is very important milling. this paper, for titanium alloy skin processing divided into two steps. The first carried out on basis path. First, obtained according to constraints milling, iterative algorithm position used. location point obtained, then projected onto parameter plane optimize vector. second based kinematic constraints. rotation machine needs meet maximum angular velocity, acceleration, jerk. optimal feed rate obtained. optimized goals with minimum motion fluctuation stop adjacent time. Subsequently, were simulated tested. Finally, simulation experimental results determined by an analysis that proved feasibility model proposed paper. measurements showed had been greatly improved terms
