Abstract

The invention discloses a complex shape joint processing method. By acquiring the original geometric data of the workpiece to be processed, a three-dimensional model of the workpiece is constructed, and the rough blank of the three-dimensional model is forged by forging, and the rough blank is processed by a numerical control machining center. Rough machining is performed on the front and back of the rough blank, the front side of the rough blank is subjected to two finishing operations in turn, and the back side of the rough blank is subjected to two finishing operations in turn; the processing method of the present application can use ordinary milling machines to mill joint parts instead of using numerical control After the machining center is completed, during the numerical milling process, the tools are reasonably selected, the rough milling program strategy is optimized, and the processing of the parts is better completed, the processing quality is guaranteed, the processing efficiency is improved, and the tool cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for processing joints with complex shapes by using a numerically controlled machine tool. Background technique [0002] With the continuous development of the aerospace field and CNC machining technology, in order to reduce weight or meet the requirements of use, the parts are mostly composed of complex features such as complex curved surfaces, inclined planes and deep cavities. Joint parts are important parts in the aerospace field. The shape of such joint parts It consists of multiple inclined planes and multiple curved surfaces, with two large sags and two large inclined planes on the back. The material of the parts is steel forgings and the removal amount is large. Due to the complex shape of this type of joint parts, it is difficult to clamp the parts during the processing process, and the processing efficiency and quality of the parts are difficult to guarantee...
