    • A tool path generation method for generating a second tool path by performing a smoothing process on a first tool path for processing a work (91) with a machine tool (1) includes a change rate calculation step of calculating a curvature change rate of the first tool path at a plurality of moving points (P n ) of the first tool path. The tool path generation method includes: a weight calculation step of calculating a moving average weight on the basis of the curvature change rate of the first tool path at each of the moving points (P n ); and a step of calculating coordinate values of the moving average of the moving points (P n ) using the weight at each of the moving points (P n ), and setting the coordinate values of the moving average of the moving points (P n ) as moving points of the second tool path.
    • (1)的工件(91)的第一工具路径上进行平滑化处理而生成第二工具路径的工具路径生成方法,其特征在于,包括:变化率计算工序,计算所述第一工具的第一曲率变化率 在第一刀具路径的多个移动点(Pn)处的刀具路径。 该刀具路径生成方法包括:权重计算步骤,基于在每个移动点(Pn)处的第一刀具路径的曲率变化率来计算移动平均重量; 以及使用每个移动点(Pn)处的权重来计算移动点(Pn)的移动平均值的坐标值,并且将移动点(Pn)的移动平均值的坐标值设置为移动点 第二条刀具路径。
