第10章 金屬切削加工件結構設計工藝性
1 金屬材料的可加工性

工性。常用材料的相對加工性見表4. 10-1,
    根據金屬的力學性能分析，硬度在170 - 230
HBW時，可加工性比較好。硬度過高,難以加工，且
造成刀具磨損快;硬度過低，則易形成長的切屑纏繞，
造成刀具發熱和磨損，零件表面粗糙。材料塑性
增加，ψ=50% -60%時，可加工性也顯著下
降。
    影響鋼、鐵可加工性的因素及銅、鋁合金加工的特
點見表4.10-2.
常用材料的相對加工性影響鋼、鐵可加工性的因素及銅、鋁合金加工的特點影響鋼、鐵可加工性的因素及銅、鋁合金加工的特點1影響鋼、鐵可加工性的因素及銅、鋁合金加工的特點2
