机械加工影响表面粗糙度的因素及改善措施

机械加工工件时加工精度与机床的精度及包括刀具、夹具、工件在内的整个系统有直接的关系,影响机械加工精度的因素很多,如机床制造零件的误差和安装误差以及加工过程中的有关操作,需要掌握机械加工中各种工艺对加工零件表面质量影响的规律,以便运用这些规律来控制零件加工的表面粗糙度,最终改善零件的表面质量、提高产品使用性能、减少机械设备的损坏、降低生产成本、提高经济效益。本文探讨了机械加工影响零件表面粗糙度的因素及改善措施。

Study of Impact Factors and Modifying Measures of Machining to Surface Roughness

When machining pieces,processing precision and machine tool precision have direct relationship with the whole system,including cutting tool,clamping tool and pieces,the impact factors of machine are various,such as machine processing pieces inaccuracy,installing inaccuracy and other operation in process,which requires the master of the rule of all kinds of process to surface quality of machining pieces in machining in order to control processing roughness of surface roughness of pieces process,improving quality of surface of pieces and feature of products,decreasing equipments damage,lowing producing cost and improving economic profits.The paper discussed impact factors and modifying measures of machining to surface roughness.
