Nc Machining Method of Concave-Convex Arc Gear

Abstract

In order to improve production efficiency and reduce processing costs, the special NC milling method of concave-convex arc gear is further studied, which provides theoretical basis for the design of special NC machine tool for concave-convex arc gear. A special NC machining method is proposed to modify the existing NC machine tools. The concave-convex arc gears are machined and kinematics experiments are carried out. The results show that the modified machine tools can achieve the desired processing objectives, and the prototype of concave-convex arc gears is machined by the modified machine tools. It can be seen that the feasibility and rationality of the design of special CNC machine tool for linear gears are verified by the comparison of processing time, motion simulation and roughness test.
