摘要： Disclosed is a method of specifying with a program language the location of a fillet to be created at the intersection of a compound curved surface. After the processings for inputting information on a curved surface and information for cutting the same (S1, S2) and calculating the curved surfaces (S3) have been completed, a system receives information on the alternative of inserting a concave fillet or inserting a convex fillet (S4). When the inputted information is for the concave fillet, based on the inputted information (S5), the system executes a predetermined calculation so as to create the concave fillet curved surface at the boundary between two curved surfaces, each on the side to which their respective normal vectors are directed (S6). On the other hand, when the input is the convex fillet, the system executes a predetermined calculation to create the convex fillet curved surface at the boundary between the two surfaces, each on the side opposite to the side to which their respective normal vectors are directed (S7).

摘要： A three-dimensional sequence of discretely given points Pi (i=1, 2, . . . ) is projected onto two mutually adjacent planes (XY plane, YZ plane) in a rectangular coordinate system. Next, two-dimensional point sequence connecting curves (TQ, TR) which smoothly connect the projected point sequences (Qi, Ri) on the respective planes are obtained, and a space curve is created using these two-dimensional point sequence connecting curves. Specifically, the common axis (Y axis) of the two mutually adjacent planes is partitioned at minute intervals, coordinates (xj,yj), (yj,zj) of points (Qj,Rj) on each of the two-dimensional point sequence connecting curves (TQ, TR) having a common axis coordinate yj of a j-th partitioning point are successively obtained, and the space curve is created by the coordinates (xj,yj,zj) (j=1, 2, . . . , n) of a sequence of three-dimensional points (Tj).

摘要： The invention relates to an NC data creation method for machining a curved surface (101) having a cutting boundary surface (102) in the depth direction. Data specifying the three-dimensional curved surface (101) and the curved surface (102) of a cutting boundary in the depth direction are inputted. When the three-dimensional curved surface (101) is defined by a set of a plurality of point-sequence paths (11i), a point sequence Q(i,j) of a tool nose corresponding to a point sequence A(i,j) is determined. Next, there is determined a projected point sequence B'(i,j) obtained by projecting the point sequence Q(i,j) of the tool nose onto a reference plane (103), as well as a projected point sequence C(i,j) obtained by projecting the first-mentioned projected point sequence onto the curved surface (102) of the cutting boundary. Thereafter, a check is performed to see whether a line segment connecting the point sequence Q(i,j) of the tool nose and a line segment connecting the projected point sequence C(i,j) on the curved surface of the cutting boundary intersect. If they do intersect, NC data up to the point of intersection P(i,j) are created. NC data are subsequently created in the same manner upon performing a pick-feed.

摘要： A cross sectional configuration creating apparatus to create a free curve by which a cross sectional configuration can be easily defined. An operator creates a cross sectional configuration (DC) on a predetermined plane coordinate system by using a cross sectional configuration creation device. When the creation of a free curve is commanded, a coordinate transformation device positions the created cross sectional configuration (DC) on a plane designated in a spatial coordinate system. Then, a free curve creation device creates the free curve from the cross sectional configuration (DC) positioned on the plane designated in the spatial coordinate system and a basic curve (BC). Further, if necessary, an inverse coordinate transformation device returns the cross sectional configuration (DC) positioned on the plane designated in the spatial coordinate system to the plane coordinate system in response to a command from the operator. The operator can correct the cross sectional configuration (DC) by using the cross sectional configuration creation device.
