摘要： A method of creating NC data including storing various approach/withdrawal patterns in dependence upon a particular zone in which a turret index point/tool exchange position (P.sub.T) is present, the zone being one among zones (ZN.sub.1 -ZN.sub.3) defined by horizonal and vertical axes passing through a point (Q) specified by a safe position coordinate (Z.sub.S) in a longitudinal direction of a workpiece (WK) and a safe position coordinate (X.sub.S) in a direction perpendicular to the longitudinal direction, and in dependence upon a plane to which a cutting starting/end point (P.sub.S) belongs, the plane being one of a plane (LPS) in the longitudinal direction of the workpiece and a plane (TPS) perpendicular to the longitudinal direction belongs. A predetermined pattern is selected from among the stored approach/withdrawal patterns based on the zone to which the turret index point (P.sub.T) actually belongs and the plane to which the cutting starting/end point (P.sub.S) actually belongs. NC data for approach and NC data for withdrawal are created using the selected pattern.

摘要： A machining condition modification definition statement (11b) is created, in an automatic programming language, specifying a machining condition modification interval at a corner portion of a part and machining conditions in this interval. A figure definition statement (11a) and a motion definition statement (11c) are created in accordance with part shape without taking the machining condition modification interval and machining conditions into consideration. When these definition statements are converted into an NC part program for laser machining executable by an NC unit, the corner portion of the part is divided into two or more machining condition modification intervals in accordance with the machining condition modification definition statement, and an NC part program for laser machining is created in such a manner that the set machining conditions will prevail in each of the intervals.

摘要： An area cutting method for cutting the interior of an area (AR) bounded by an external shape curve (OLC) including a number of straight lines (S1, S2, . . . S6) and a circular arc (A1). The method includes linearly approximating a circular arc portion (A1') of an offset curve (OFC) which is offset a predetermined amount from the external shape curve. Then an area bounded by the linearly approximated offset curve is divided into a plurality of convex polygons (PG1-PG3). The centroid (Wi) of each convex polygon and the mid-points (M1, M2) of boundary lines (B1, B2) of two mutually adjacent convex polygons are calculated, and a base line (BL) is generated by successively connecting each centroid and each mid-point. Straight lines (L1-L14) connecting the centroids (Wi) of the convex polygons and the apices (P1-P10) of the convex polygons, and straight lines (BL1-BL4) connecting the mid-points (M1, M2) and the two ends (P1, P4; P4, P7) of the boundary lines bisected by the mid-points are partitioned into a predetermined number of partitions. A tool is moved along plural closed paths (CPT1, CPT2, . . . ) obtained by connecting partitioning points (P.sub.a1, P.sub.a2, . . . P.sub.a18 ; P.sub.b1, P.sub.b2, . . . P.sub.b18), which correspond to the straight lines (L1-L14, BL1-BL4), in such a manner that the base line (BL) is enclosed. The tool is moved along the base line (BL) and along the offset curve (OFC).

摘要： A multiple-layout designation method rapidly and easily performs preparatory work for numeral control (NC) data preparation, in which one of contours displayed on a graphic display of an automatic programming device is manually selected as an NC data preparation object (S1), and the necessity of contour duplication is manually selected (S2). When the original contour is duplicated on the display by a processor of the programming device in response to manual setting of the name of a contour group consisting of the displayed contour and duplicated contours to be obtained by duplication (S3 and S4), or when the name of the displayed contour is manually set (S6), contour data for the contour or the contour group is generated. After setting of all the names of all the contour(s) or contour group(s) as NC data preparation objects, machining condition data associated with the contour name, or common to the original contour and the duplicated contour and serving as the machining condition data regarding the contour name, is manually set (S7 and S8). After setting of all the machining condition data, NC data employed for machining of each of the contour(s) and the contour group(s) are automatically prepared based on the contour data and the machining condition data concerned (S10).

摘要： High-speed data processing units are interposed on one-to-one basis between a host computer and each of NC units corresponding to each of NC machine tools. Each of the high-speed data processing units converts data transmitted from the host computer to each of the NC machine tools into NC data, and then inputs the data to each of the NC units, thereby making unnecessary for the NC units and the host computer to convert the data into NC data. Further, each of the high-speed data processing units temporarily stores machining data or the like transmitted from the host computer, thereby enabling each of machine tool bodies to continue its machining operation without being disturbed by the timing of data transmission.

摘要： An interpolation method in an automatic programming, capable of properly determining and programming target movement amounts for individual axes in each interpolation cycle at the time of executing a numerical control program. In the case where the length (P') of the last one of a plurality of sub-sections, obtained by dividing a section from the starting point (A) to the end point (B) of each block in a program by a target movement amount (P) per interpolation cycle, is smaller than the value (P), and when an angle (.theta.) between the paths of the block concerned and the next block is smaller than a reference angle or when the angle (.theta.) is larger than the reference angle and the sub-section length (P') is smaller than a reference length, an intersection at which a sphere having the starting point (an) of the last sub-section as its center and theh value (P) as its radius crosses the target movement path of the next block is derived by the overlapping process, and the interpolation process for the last sub-section is effected with the intersection used as the target end point of the last sub-section. On the other hand, when the angle (.theta.) and the length (P') are larger than the reference angle and reference length, respectively, the interpolation process is effected with the original end point (B) used as the target end point of the last sub-section, without effecting the overlapping process.

摘要： The invention relates to a corner shape insertion method for inserting a corner shape such as a chamfered or rounded corner portion having prescribed dimensions at a corner of a profile (OLF) comprising a plurality of figure elements (S1-S8). When limits (indicated by the dashed-line segment) of the profile in which corner shapes are to be inserted is specified by designating two figure elements (S1, S5) of the prolfile (OLF), angles defined by mutually adjacent ones of the figure elements within the limits of the profile are obtained and it is determined whether the angles reside within set angular limits. If an angle lies within the set angular limits, the corner shapes (C2, C4) of prescribed dimensions are inserted between the figure elements.
