摘要： Method of generating tool movement path data 9 includes determining a tool constraining surface (12) which is offset from a three-dimensional surface (22) to be generated, by a distance equal to a radial dimension of rotary machining tool (20), in a direction normal to the three-dimensional surface, determining tool path constraining surfaces (32) for constraining the tool according to the geometry of the three-dimensional surface, and obtaining three-dimensional curved line equations representing intersection lines (34) between the constraining surfaces (12, 32). Since desired curved surfaces may be used as the tool path constraining surfaces (32), the tool movement path can be suitably determined with high freedom depending upon the geometry of the three-dimensional surface (22) to be generated. The tool movement path data generated from three-dimensional curved line equations have a reduced volume but assure high machining accuracy, as compared with tool movement path data consisting of a multiplicity of cutter location points to which the tool is moved.

摘要： The cutting path generation method defines a sequence of discrete points spaced along the required cutting path for the cutting machine, for guiding the movement of the latter. The spacing of the successive points is calculated using the relationship between the radius of curvature of the cutting path, the spacing between the points and the displacement rate of the cutting device, to provide a maximum displacement rate, with subsequent generation of spaced points at the calculated relative spacing.

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.
