摘要: 按磨削点在连杆颈上匀速运动的原则建立了切点跟踪磨削法的运动模型,提出了通过坐标转换把曲轴切点跟踪磨削转换成按普通外圆磨削状态来进行分析的新思路,从运动学的角度分析了切点跟踪磨削法对加工误差的影响,探讨了切点跟踪运动对当量磨削厚度和磨削力的影响及变化规律,给出了数控补偿量的计算公式和修正后的运动模型。

Abstract: A motion model of tangential point tracing grinding has established according to the principle of grinding point’s uniform motion on the neck of connecting rod,and a new idea that changes the crank tangential point tracing grinding into the state of common external grinding is described through coordinate converting.According to the motion model,the influence of machining error caused by the tangential point tracing is analyzed.The influence and change rules of equivalent grinding thickness and grinding force of the tangential point tracing motion are discussed.The computer formula of NC compensation and the revised motion model are given.

Key words: Coordinate converting Equivalent grinding thickness, Crank, Machining error, Tangential point tracing grinding Motion model
