Research on Machining Method of Spatial Rotary Curved Surface

Abstract:

In order to get high tapered spatial complicated curved surface parts and solve the difficult problems of machining spatial curved surface parts in high-speed wire cut electronic discharge machining (WEDM), a turnover NC rotary table based on the mathematical models of spatial complicated curved surface was designed. Through establishing the mathematical equations of the general motion form, the several major processed forms are obtained. Then the multi-axis movement WEDM system and its experimental device were established. Through machining experiment of the several major processed forms, it shows that the multi-axis movement WEDM system has high machining quality and low cost and has practical applicability, to confirm the feasibility of the polar coordinates processing system in space ruled surface, and to produce a novel research direction for solving the difficult problems of machining spatial curved surface parts.
