近年来，对具有复杂形状的模具的精密加工的需求一直在增加。虽然数控机床在机械加工中得到了广泛的应用，但为了满足日益提高的加工精度要求，仍然需要对加工误差进行补偿。然而，加工误差补偿是一个需要大量技术、时间和成本的操作。本文提出了一种新的加工误差补偿方法。根据三坐标测量机测量的加工误差，对已加工零件的三维曲面数据进行修正。根据修改后的3D表面数据生成用于加工误差补偿的补偿NC程序。
Recently, a demand for precision machining of dies and molds with complex shapes has been increasing. Although CNC machine tools are utilized widely for machining, still machining error compensation is required to meet the increasing demand of machining accuracy. However, the machining error compensation is an operation which takes huge amount of skill, time and cost. This paper deals with a new method of the machining error compensation. The 3D surface data of the machined part is modified according to the machining error measured by CMM (Coordinate Measuring Machine). A compensated NC program is generated from the modified 3D surface data for the machining error compensation.
