Method for cutting tool escape free reticulate pattern on surface of high-precision thin-wall shell

Abstract

The invention relates to a technology for cutting reticulate patterns on the surface of a shell, in particular to a method for cutting tool escape free reticulate patterns on the surface of a high accuracy thin-wall shell, which solves the problem that tool escape free reticulate pattern cutting can not be realized on the surface of the high accuracy thin-wall shell at present. The method comprises the following steps of: firstly, calculating the strip amount and the lead of a levorotation spiral groove and a dextrorotation spiral groove, wherein the levorotation spiral groove and the dextrorotation spiral groove form shell surface reticulate patterns; secondly, installing and clamping the shell on turn-milling processing center equipment, milling a section of spiral groove by a milling cutter at the initiating end and the termination end of each spiral groove by the turn-milling processing center equipment; and thirdly, processing the levorotation spiral groove and the dextrorotation spiral groove according to a method of turning multi-head threads by using a threaded turning tool to replace the turn-milling processing center equipment so as to form the reticulate patterns, and when each spiral groove is processed, cutting from the processed initiating end spiral groove part, and stopping cutting at the processed termination end spiral groove part. The invention has clear technological process, can realize cutting of the tool escape free reticulate patterns on the surface of the high accuracy thin-wall shell and has little deformation of the shell after cutting and uniform and consistent reticulate pattern depths.

Description

technical field [0001] The invention relates to a shell surface texture cutting process, in particular to a high-precision thin-wall shell surface texture cutting method without tool relief grooves. Background technique [0002] Mesh texture is a metal decoration that acts on the surface to have the characteristics of wear resistance, anti-skid, and directional cracking. In the mechanical industry, the texture is widely used in wear resistance and anti-skid. In the fields of aviation, aerospace and navigation, the texture mainly plays the role of directional cracking. At present, the known cutting methods of texture include: rolling forming on a lathe with a texture knurling cutter or one-time rolling forming on a special equipment, or using the method of processing multi-thread threads on a lathe. However, due to the large cutting force of the rolling method and the easy deformation of the parts, it is impossible to use the rolling method to realize the texture processing ...
