本文提出了一种在被自由曲面覆盖的物体与刀具之间生成偏置曲面的方法。利用互相关函数计算偏移曲面。对于离散互相关函数的计算，刀具形状和自由曲面对象采用体素表示方法，通常存在量化误差。为了减少量化误差，在工具和物体表面的单元被赋予中间值。将这种偏移量计算方法用于加工布布尔异常分布图模型的自由曲面对象。
This paper proposes a method to generate an offset surface between a tool and an object which is covered with free form surfaces. Crosscorrelation function is used to calculate the offset surface. For calculating the discrete crosscorrelation function, the tool shape and the free surface object are represented by Voxel representation method, which usually includes quantization errors. Intermediate values are given to the cells at the surfaces of the tool and the object to reduce the quantization errors. This offset calculation method is used for machining a free form surface object that is a die for Boubure anomaly distribution map model.
