摘要：通过设定以相当于旋转加工工具(20)半径尺寸的距离、沿面法线方向离开要制作的三维曲面(22)的工具约束曲面(12)，同时根据该三维曲面(22)的形状设定用于约束旋转加工工具(20)移动路径的路径约束曲面(32)，求出作为三维曲线式的两个曲面(12、32)的交线(34)，生成工具移动路径数据。由此，可以把路径约束曲面(32)设定成任意曲面，提高了工具移动路径的设定自由度，可根据要制作的三维曲面(22)的形状设定适当的工具移动路径，同时利用三维曲线式生成工具移动路径数据，与利用数个工具通过点组成的点阵数据生成工具移动路径数据的场合相比较，可维持高的加工精度，减少数据量。

摘要： This invention provides a novel tool path planning method for five-axis flank milling by imposing the constraints of curve interpolation on the tool path. The tool motion is described in the form of spline curves during its optimization-driven calculation process, instead of discrete cutter locations in CNC linear interpolation. The coefficients of the curve equations are generated by minimizing accumulated geometrical errors on the machined surface using optimization algorithms. The continuity imposed by the spline motion reduces uneven modifications of cutter locations during the optimization process. The resultant tool path yields superior.

摘要： An apparatus for calculating a tool reference plane utilizes a machining plane model and an inversed tool model to create a collection of sphere regions having three dimensional grid points as their center, and identifies a nearest point on each of the model planes from the respective center point of the sphere regions. The positions within the tool reference plane can be accurately identified to the degree of the grid interval of the three dimensional grid points using the machining plane model and the inversed tool model consisting of the collection of sphere regions. By using the nearest point on each of the model planes, the position of the tool reference plane is identified using the accuracy created by the model planes. According to this apparatus, a tool reference plane can be created accurately irrespective of the shape of the machining plane model.

摘要： A tool restraining curved plane (12) which is spaced from a three-dimensional curved plane (22) to be produced by a distance corresponding to a radius of a rotary working tool (20) in the direction of the normal of the plane is set, and a curved plane (32) for restraining a path, along which the rotary working tool (20) is moved, in accordance with the shape of the three-dimensional curved plane (22) is set, a cross line of these curved (34) planes being determined as a three-dimensional curve expression, whereby data on a tool moving path are prepared. Since an arbitrary curved plane can be set as the path restraining curved plane (32) in this manner, the degree of freedom of setting a tool moving path becomes higher, and a suitable tool moving path can be set in accordance with the shape of the three-dimensional curved plane (22) to be produced. Since the data on a tool moving path are prepared by a three-dimensional curve expression, the amount of data can be reduced with a high machining precision maintained in comparison with a case where the data on a tool moving path are prepared on the basis of sequence of points data comprising a plurality of tool passing points.
