    • A method for determining the deformation of workpiece on a grinding machine is proposed, in which the deformation of workpiece can be determined without using the less reliable initial deformation.Suppose the deflection at the beginning and the final deflection for the last time be T' (s) and T' (e), respectively, and the deformation preset for the grinding completion time be Ta, the deformation T (s) at the operation start time for the workpiece in the present time is approximated by the expressionT(s)=T' (s)-T' (e)+TaSuppose the shift of grinding wheel for the workpiece be .DELTA.A, and the change in diameter be D(x)-D(s), the deformation T(x) at a time for the present time is determined from the expressionT(x)-.DELTA.A+(D(x)-D(s))/2+T(s).
    • 提出了一种用于确定研磨机上工件变形的方法,其中可以确定工件的变形而不使用不太可靠的初始变形。 假设最后一次的起始偏转和最后一次偏转分别为T'(s)和T'(e),磨削完成时间预设的变形为Ta,操作时的变形T(s) 目前工件的起始时间由表达式T(s)= T'(s)-T'(e)+ Ta近似。假设工件砂轮的移动为DELTA A,直径变化 是D(x)-D(s),目前时间的变形T(x)由表达式T(x)-DDTA A +(D(x)-D(s))/ 2+ T(s)。
