摘要： An area machining method capable of generating tool paths with no insufficient cut portion. First, a part profile contour indicating a profile contour for area machining and various machining conditions such as tool radius, depth of cut and the like are preset. Then the outmost offset contour and other subsequent offset contours are obtained, the outmost offset contour being offset along the part profile contour by an amount of the sum of a tool radius and finishing allowance, and the other subsequent offset contours being offset repeatedly from the outmost offset contour in sequence by an amount of depth of cut in the inside direction. Next, contours of insufficient cut portions which are produced between adjacent offset contours are obtained. Subsequently, tool paths each of which connects between offset contours and between an offset contour and a corresponding insufficient cut portion contour are outputted. At this time, insufficient cut portion contours are added to tool paths by changing a tool path to an insufficient cut portion contour if the insufficient cut portion contour is present near the current path while outputting an offset contour as a tool path.

摘要： An area machining method for efficiently hollowing out an area which contains a part of an outline of a workpiece is disclosed. An outward offset line is set outside the workpiece with a predetermined offset distance. Then a series of offset contours (i.e., the elements of the tool path) are defined within the region between the outward offset line and the final part contour. Since the offset distance to the outward offset line is set zero, all the offset contours share a segment of the outward offset line. Except for this common segment, the offset contours are given a cutting feedrate.

摘要： A cutting shape (Q1) is approximated to a polygonal shape (Q3). Division points are obtained by dividing line segments linking each vertex of this polygonal shape (Q3) with the cutting start point (PS1) by the same number. Corresponding division points on each line segment are then linked to obtained a plurality of polygonal closed paths (PH2-PH4). Here, the innermost closed path (PH2) is devised such that at least a portion thereof passes outside the cutting starting hole centered on the cutting start point (PS1).

摘要： A method of and an apparatus for determining a machining sequence of wire-cut electric discharge machining capable of easily changing a machining sequence in continuously machining a plurality of machining shapes. By making a sequence of a combination of a shape to be machined and a machining stage for the shape to be machined capable of being edited, the machining sequence in the case where the plurality of machining shapes are machined continuously is made easily changeable. In the method for specifying the machining sequence, two different modes are available. In a first mode, a plurality of standard machining patterns are prepared in advance, and the machining pattern is changed to form a desired machining pattern. In a second mode, a sequence of a combination of a plurality of shapes to be machined and the machining stages for a selected machining pattern is changed to form a desired machining pattern.

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： 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： 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.
