摘要
本文通过研究燃气轮机某关键件螺母的机械加工工艺,针对在加工过程中螺纹的精度和表面粗糙度保证困难,螺纹的跳动量超差,铣槽时造成零件薄壁变形等问题,逐一进行工艺分析,增加零件刚性,防止零件振动,避免走刀速度的影响,选用螺旋升角修正,由UG刀心编程方式,小余量高速铣加工应用到该薄壁零件,解决了薄壁变形等问题。并对生产现场的实际情况自制工装、编制并调试数控加工程序,最终加工出合格的零件,保证产品质量。
Through the study of the machining process of gas turbine key components of a nut, the screw during machining accuracy and surface roughness to ensure the difficulties, runout thread super bad, cause trough Milling Thin-walled Parts deformation process analysis, one by one, increasing the rigidity of the parts, to prevent parts vibration, avoid the influence of cutting speed, selection of helix angle correction, by UG cutter programming small margin, high-speed milling machining is applied to the thin wall parts, solves the problem of thin wall deformation. And the actual situation of the production site of the self-made fixture, compile, and debug the NC program, the final processing of qualified parts, ensure the quality of the products.
