Method for improving CG internal thread cutting machining precision of stainless steel material

The method for improving the CG internal thread cutting machining precision of the stainless steel material is applied to milling machining of CG internal threads of stainless steel products, geometric parameters of a thread milling cutter are mainly utilized, and numerical control machining equipment is selected, so that the machining precision of the CG internal threads is improved. By optimizing cutting machining parameters, machining routes and the like, the defects existing during traditional manual internal thread tapping are overcome, for example, the defects that a single pitch diameter value does not meet the tolerance requirement, the thread form surface roughness Ra does not meet the requirement, the thread form is incomplete, cracks or interlayers exist and the like are overcome. The machining quality and the machining efficiency of the CG internal threads are improved, and therefore the qualified rate of product machining is greatly increased. 本发明提供了一种提升不锈钢材料CG内螺纹切削加工精度的方法，本发明应用于不锈钢产品CG内螺纹的铣削加工，主
