机械制造过程中金属切削工具的应用

摘要

在金属切削加工过程中,刀具的切削部分是在较大的切削力、较高的切削温度和剧烈的摩擦条件下进行的.刀具材料的选择是否恰当,直接影响着刀具的寿命、切削效率及零件的加工质量.%In the metal cutting process, cutting part of tool is under the conditions of the larger cutting force, high temperatures and severe friction. The appropriateness of the choice of tool material direct effects the life of the tool, cutting efficiency and machining quality.
