摘　　要：为解决插削铝合金薄壁深窄槽存在的效率低、精度和可靠性控制困难等问题,提出采用锯片铣刀的替代方案,首先通过切削过程仿真,研究锯片铣刀加工中切削力、切削热、塑性应变等变化规律和影响因素,为设计加工参数和工艺方案提供参考,然后开展试验研究,对薄壁深窄槽进行小批量试制,加工后抽检各项精度指标均满足要求。新工艺方法提高了深窄槽的加工效率,并有效控制了切削振动,保证了加工质量,研究证实了锯铣工艺方法在薄壁深窄槽加工方面的可行性。In order to solve the problems of low efficiency,precision and reliability control of the thin-walled deep-necked slot of aluminum alloy,an alternative to saw blade milling cutter is proposed.Firstly,the cutting force simulation is used to study the cutting force and cutting in the saw blade milling cutter.The variation law and influencing factors such as thermal and plastic strain provide reference for designing processing parameters and process schemes,and then carry out experimental research.Small-scale trial production of thin-wall deep and narrow grooves,and various precision indexes of sampling after processing meet the requirements.The new process method improves the processing efficiency of deep and narrow grooves,and effectively controls the cutting vibration to ensure the processing quality.The research confirms the feasibility of the sawing and milling process in the processing of thin-wall deep and narrow grooves.
