借助运动合成创造的新加工法

SOME NEW MACHINING METHODS WITH THE AID OF COMPOUND MOTIONS

本文提出了一套利用圆和直线运动组合的方法来加工成形零件的新理论。针对我国机械制造发展中出现的新问题,在本理论的指导下,发明了五项新工艺专利,多数已在工厂投产。

The paper describes a new theory and methods for designing hyperbola, degenerate circles, involute and roulette curves which have been applied in grinding convex involute gears, cutting special profiles on a gear shaper, grinding the race-way of ball thrust bearings, form grinding and grinding cyclo-cycloidal gears with an abrasive belt. All these applications have been used in industruy with considerable benefits. The curves are produced by different combinations of straight line and circle motions, Given the curve parameters of the workpieces to be machined, the best approximate curve can be obtained from a computer program designed for this purpose.
