摘要
粗加工进给速度优化是指以最高生产率为目标函数 ,以最大主功率等为约束条件 ,按照用户设定的优化参数自动调整不同加工段的进给速度来保持恒定最大主功率状态 ,从而使单位时间内的材料切除量最大。使用仿真、验证与优化软件VERICUT ,可以自动编制带有最佳进给速度的加工程序 ,减少或避免人工调整进给速度产生的种种问题 ,大量缩短加工时间。以粗加工为例 ,对其优化原理进行了探索 ,初步建立了优化数学模型 。
Feed rate optimization for the rough machining means that it takes maximum machining efficiency as object function, it takes maximum main power and so on as limitation, feed rate in different stages are automatically adjusted according to optimization parameters designed by customers to keep maximum main power in a constant state, which makes material removal rate maximum. Using the simulation, verification and optimization software of VERICUT can automatically make NC program including the optimum feed rate, decrease or avoid many problems raised in adjusting feed rate manually, greatly shorten the machining time. Taking rough machining for example, this paper explores the optimization principle, primarily builds the optimization mathematical model, and realizes optimization through a typical case.
