Abstract A model is proposed for calculating the actual radial feed in internal grinding on a CNC machine. The model establishes the relation between the actual and programmed feed, as a function of the cutting forces, the elastic deformation of the machining system, the cutting conditions, the wheel–workpiece contact geometry, the wheel characteristics, and other parameters. The model is used to predict the change in radius of the machined hole surface in the workpiece, from the initial to the final value for a specified automatic cycle, in various internal-grinding conditions. The model provides the basis for multiparametric optimization of the grinding cycles in multidimensional control-parameter space.

内圆磨削中程序进给运动与实际进给运动的关系

摘要 提出了一种计算数控机床内圆磨削实际径向进给量的模型。该模型建立了实际进给和编程进给之间的关系，作为切削力、加工系统的弹性变形、切削条件、砂轮-工件接触几何形状、砂轮特性和其他参数的函数。该模型用于预测工件加工孔表面半径的变化，从初始值到指定自动循环的最终值，在各种内圆磨削条件下。该模型为多维控制参数空间中磨削循环的多参数优化提供了基础。
