Abstract

The invention relates to a numerical control machining method for a thin-wall copper electrode, which comprises the following steps of: reasonably selecting a clamp, a cutter and a cutting parameter for improving the working efficiency; reasonably distributing the step and a feed route; controlling the deformation of a workpiece; after rough machining is finished, mounting a residual stress release notch at the side surface of the workpiece; eliminating deformation caused by residual stress during rapid rough machining, wherein a rough machining cutter adopts a ball end milling cutter instead of a generally used flat end vertical milling cutter; and carrying out symmetrical machining on the design of the feed route. The method for machining the workpiece sequentially comprises the steps of machining a reference surface 5 and a reference surface 4, clamping for positioning, roughly machining, machining a reference surface 2 and a reference surface 3, machining a stress release notch 9, finely machining and detecting precision. By adopting a plurality of process measures for controlling deformation, the invention has the advantages of greatly reducing the deformation of machining parts and effectively improving the precision and the stability of the parts. By actually measuring the workpiece on a three-coordinate measuring machine, a surface roughness value can be reduced to minimum and can completely meet the requirement on products.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a high-efficiency numerical control machining method for thin-walled parts with strict requirements on deformation control. Background technique [0002] The processing of thin-walled parts in injection mold manufacturing has always been a difficult problem in CNC machining. The control of deformation and the improvement of processing efficiency are a pair of prominent contradictions. How to solve this prominent contradiction has become a research topic for many researchers. At present, the most efficient and reliable method is to apply high-speed processing technology and complete processing on high-speed machine tools. However, high-speed machining machine tools have not been fully popularized, and most mold companies still use ordinary CNC machining methods. Contents of the invention [0003] The object of the present invention is to disclose a numerical control...
