摘要
综述近年来激光加热辅助切削加工技术的研究进展。在实验研究方面,总结了激光加热辅助车削、铣削、钻削、磨削等不同工艺过程的加工特点,阐述了激光参数和切削参数对加工质量的影响。研究表明:在一定范围内,适当提高激光功率、降低切削速率、减小进给量有利于切削区材料的充分软化,可改善工件材料的切削加工性,提高加工效率和加工质量。目前,激光加热辅助切削加工仿真研究主要集中在切削温度场与切削过程仿真。通过建立温度场模型,可预测材料去除最优温度范围,优化加工工艺参数。切削过程仿真探讨应力、应变、温度等物理量的影响,为实际加工中控制零件表面质量提供了依据。后续工作应进一步加强在加工机理、加工工艺、仿真优化等方面的研究,建立完善的激光加热辅助切削加工数据库,以促进该技术的工业应用。
This paper reviews the recent research progress on laser assisted machining technology.On the experimental research aspect,the technical characteristics of various processes including laser assisted turning,milling,drilling,and grinding have been summarized,and the effects of laser and cutting parameters on machining quality have been stated.Investigations show that properly increasing laser power and decreasing cutting speed and feed rate within limits is propitious to fully soften the workpiece material in the cutting zone,and therefore improves the machinability of the workpiece material and enhances the machining efficiency and quality.Current simulation research on laser assisted machining is mainly focused on the cutting temperature field and machining process.By establishing the model of temperature field,the best temperature range for removing workpiece material can be predicted and the cutting parameters can be optimized.Cutting process simulation discusses the influence of physical quantities in machining such as stress,strain,and temperature,providing a basis for controlling the quality of the machined surface in real operations.In the future,the study on machining mechanism,processing techniques and simulation for optimization should be strengthened,and the data base for laser assisted machining processes should be found,in order to promote the industrial application of the technology
