The purpose of this research is to develop the high speed and high accuracy machining system that is capable of responding appropriately to next generation keeping advantage in the worldwide. Recently the requirement of machining accuracy for die and mold becomes close to the micro meter order even if using the common machine tools. Current machining system is composed with the element of CAD, CAM, CNC and machine tool and each one is developed individually in other makers. It is necessary to realize the new high speed and high accuracy system that these elements are integrated and fused with data stream.In this research, each element is standardized by a servo data which is a final data to control servo motors built in the table of machine tool. The servo data is a command positions per interpolation time. Generation of this servo data from the geometric model of objective shape is named the geometrical interpolation. The geometrical interpolation calculates servo data considering acceleration and deceleration position which are suitable for the geometry of objective shape directly. On the other hand, the errors such as motion error, tool deflection error and so on occur during actual machining processes. To compensate these errors, the prediction compensation is developed. The prediction errors are calculated by NC machining simulation by using servo data, then the servo data is corrected based on prediction errors.In this report, geometrical interpolation and prediction compensation are developed and validated by experimental measurement of traced positions. The objective shape is combined of circle, arc and line of the experiment and compensated error is a motion error. As a result of this research, it is evident that proposed system is able to reduce the position error caused by interpolation error of NC program and motion error.

本研究的目的是开发高速和高精度的加工系统，能够适当地响应下一代保持全球优势。近年来，模具的加工精度要求已接近微米级，即使在普通机床上加工也是如此。目前的加工系统是由CAD、CAM、CNC和机床组成的，每一个都是在其他制造商单独开发的。为了实现高速高精度系统，需要将这些元件集成并融合到数据流中，在本研究中，每个元件都被一个伺服数据标准化，该伺服数据是控制机床工作台中伺服电机的最终数据。伺服数据是每插补时间的命令位置。从目标形状的几何模型生成该伺服数据被称为几何插值。几何插补直接计算与目标形状几何形状相适应的加减速位置伺服数据。另一方面，在实际加工过程中会产生运动误差、刀具偏转误差等误差。为了补偿这些误差，预测补偿的发展。通过数控加工仿真，利用伺服数据计算预测误差，并根据预测误差对伺服数据进行修正，提出了几何插补和预测补偿方法，并通过跟踪位置的实验测量进行了验证。实验的目标形状是圆、弧和直线的组合，补偿误差是运动误差。研究结果表明，该系统能够有效地减小由数控程序插补误差和运动误差引起的位置误差。
