研究了数控与普通铣床多次走刀端面粗铣加工中铣削用量的计算机辅助优化。以最大生产率为目标 ,走刀次数和每次走刀下的铣削用量为变量 ,建立了多次走刀端面粗铣加工的数学优化模型 ;提出了优化分析与数字搜索相结合的优化策略 ,开发了相应的 CAM软件。实验验证了优化策略及软件的有效性与经济性 The computer-aided optimization of the milling amount in rough milling of NC and ordinary milling machines was studied. Taking the maximum productivity as the goal, the number of passes and the amount of milling under each pass as variables, a mathematic optimization model of roughing and milling for multiple passes was set up. An optimization strategy based on optimization analysis and digital search was proposed and developed The corresponding CAM software. Experiments show that the optimization strategy and the effectiveness and economy of the software
