金属切削加工中冷却润滑液的使用会增加加工成本,污染环境,而干切削和近干切削可以彻底消除或极大地减少冷却润滑液的使用,所以其成为许多单位研究热点。近来奥氏体不锈钢在各行业内应用越来越广,为了充分了解奥氏体不锈钢的切削性能,本文对奥氏体不锈钢0Cr18Ni9在传统乳化剂、干车削和微量润滑车削条件下进行切削试验,通过设计多因素正交试验方法,建立压电式测力系统测量切削过程中的动态平均切削力,在不同的冷却润滑方式下,比较背吃刀量、切削速度、进给量等切削用量对切削力的影响,得出各个因素的影响曲线图,从而揭示奥氏体不锈钢0Cr18Ni9在车削过程中的切削力变化情况,为实际的生产加工积累和提供基础数据。
The use of cooling lubricant in metal cutting process will increase the processing cost and pollute the environment. However, dry cutting and near-dry cutting can completely eliminate or greatly reduce the use of cooling lubricating fluid, so it becomes a hot research topic in many units. Recently, the application of austenitic stainless steel in various industries is more and more widely. In order to fully understand the cutting performance of austenitic stainless steel, the austenitic stainless steel 0Cr18Ni9 is cut under traditional emulsifying, dry turning and micro- Through the design of multi-factor orthogonal test method, the piezoelectric force measurement system is established to measure the dynamic average cutting force in the cutting process. In different cooling lubrication modes, the comparison of back cutting amount, cutting speed and feed rate Cutting force, draw the impact of various factors curve, thus revealing the cutting force of the austenitic stainless steel 0Cr18Ni9 in the turning process, accumulation and provide the basic data for the actual production and processing.
