Method for machining spatial curved surface of large conical surface connecting pipe on three-axis linkage milling machine

Abstract

The invention provides a method for machining a spatial curved surface of a large conical surface connecting pipe on a three-axis linkage milling machine. The method comprises the following steps thata workpiece digital model is established and analyzed, a process scheme is formulated, and machining of the spatial curved surface of the large conical surface connecting pipe on the three-axis linkage milling machine through rough machining, semi-finish machining and finish machining. The invention provides a new segmentation method machining scheme, the problem that the complex spatial curved surface cannot be machined on the three-axis linkage milling machine is solved, and the segmentation method provides a new solution thought for machining of the complex curved surface; the angle milling head machining scheme adopted by the method solves the limitation of five-axis machine tool machining, the problems that a conventional machining method cannot meet the size requirement, the machining efficiency is low, and the machining cost is high are also solved; and more importantly, the angle milling head machining scheme provides a valuable solution for machining similar bidirectional internal corners, the surface quality of products is greatly improved, and meanwhile the machining efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of processing methods on a three-axis linkage milling machine, and in particular relates to a processing method of a large-scale conical surface connecting space curved surface on a three-axis linkage milling machine. Background technique [0002] There are two types of existing processing technologies for the large complex space surface formed by the intersecting of cylinder and large cone. shape processing. Five-axis machine tool processing is limited by equipment and processing procedures. First, the current five-axis machine tools are expensive. If the company’s products involve few five-axis machine tools, it will be too wasteful. Second, there are few technicians who are proficient in five-axis machining procedures, and the salary of technicians very high. The use of three-axis machine tools for approximate machining can not guarantee the dimensional accuracy requirements of the workpiece, and the su...
