摘要
不锈钢材料在金属切削加工中属于难加工材料 ,而奥氏不锈钢类材料又是难中之难 ,无论其切削工艺、加工成本及加工质量都为当前机械加工的难题。通过不断探索寻找、确定最佳刀具几何角度、材料、切削液等工艺 ,采用试验分析方法 ,确定奥氏体不锈钢车削工艺的方法 ,具有时间短、准确可靠、针对性强的特点。通过分析对比 ,取得了合理的工艺参数。实验结果表明 ,能较好地解决奥氏体不锈钢车削加工过程中存在的切削力大、切削温度高、刀具耐用度低及生产效率低的问题 ,工件质量显著提高 ,基本解决了奥氏体不锈钢切削难的问题。
Stainless steel is a difficult material in the metal machining process,however austenite is the most difficult inside of the stainless steel material,especially in the craft of slicing,the cost of machining and the quality of the process.People constantly investigate in this problem for the certain craft parameter.The examine analysis method which is a good way to insuer the austenite of stainless steel process craft have the fast and accurate features.The reasonable craft parameter can be get from the analyzing and comparing the experiment result.
