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： An NC data execution method which permits an efficient checking of the validity/invalidity of NC data through a simple operation. In an NC data execution process, a processor of an automatic programming apparatus reads out NC data, block by block, from a memory (S2), and determines whether or not the read NC data block satisfies an NC data execution interrupt condition, e.g., whether or not the data block contains a specific code (S3). When the interrupt condition is fulfilled, the data block is displayed at an input display field on the screen (S4), and then the NC data execution, including a graphic display operation based on the content of the data block satisfying the interrupt condition, e.g., a display of a tool path and the reading and display of the next block, is automatically interrupted, whereby the operator is allowed to thoroughly check the data block satisfying the interrupt condition. After the data checking, the NC data execution is restarted upon input of an interrupt disable command through the operator's key operation (S5-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： When an item (T.sub.1 or T.sub.2) for revising chamfering or rounding is selected from a menu table (108b) of a tablet device (108), all corner portions (E.sub.1 -E.sub.3) included in profile (A.sub.1) and pertaining to the revision item (e.g., the item for revision rounding) are displayed in a color different from the other portions of the profile. Thereafter, a corner portion (E.sub.1) requiring revision is designated by a graphic cursor (K), whereupon the corner portions (E.sub.2, E.sub.3) other than the designated corner portion return to the original color so that only the designated corner portion (E.sub.1) may be identified for revision. .

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 method of displaying a structure (SML) three-dimensionally, in which a rectangular parallelepiped (RP), having on each of its sides distances (L.sub.x, L.sub.y, L.sub.z) between minimum and maximum positions along each axis of a structure (SML) is constituted by a set of a number of unit solids, e.g., unit cubes (UC), of the same shape and same dimensions. The structure is represented by information indicating whether each unit solid is part of the structure (SML). Individual ones of the unit solids constituting the structure (SML) are displayed in order starting from unit solids seen on a the front side of the structure. The face of a unit solid overlapping a face of a unit solid already displayed is not displayed; instead, only the visually foremost faces thereof are displayed, thereby displaying a perspective view of the three-dimensional structure (SML).

摘要： A prescribed menu item on a menu table (108b) is picked to designate a method of defining a figure element, and a predefined figure element displayed on a display screen (106) is picked. A processor (102) defines a new figure element using the picked figure element definition method and the picked figure element, and defines a part profile using figure elements picked in the order of tool motion when the defining of all figure elements is completed. In this case, the processor expresses, in a first format based upon an automatic programming language, figure elements and the part profile as defined, and stores the figure elements and part profile in a storage ares (103b). Using a second format for the figure elements, each point is expressed as the coordinate values thereof, each straight line expressed as the coordinate values of two points, and each circle expressed as the coordinates of the center of the circle and the radius of the circular arc, are stored in a storage area 103c. when there is a request for output of the part profile, the processor (102) outputs the figure elements and the part profile in the automatic programming language using the first format. When a figure element designated by a graphic cursor is identified and when the figure is displayed, processing is performed using the second format.

摘要： The invention relates to a method of creating NC data for machining the interior of an area. The method includes displaying, on a graphic display unit (106), contours (CNT1, CNT2) inputted in order to specify the area (AR.sub.M), recognizing the area (AR.sub.M), which is designated by a graphic cursor by manipulation of a tablet (108) and painting the interior of the area in a predetermined color, subsequently removing the paint in a linear area (AR.sub.1), having a width equivalent to a width of a tool, which connects a machining starting point (P.sub.S) and a machining end point (P.sub.E) designated by the graphic cursor, adopting the machining end point as the next machining starting point, thereafter inputting machining end points in succession, and creating NC data for machining the interior of the area (AR.sub.M) by traversing a finally designated machining starting point and machining end point while moving the tool linearly.
