摘要： A method of approach in area cutting includes giving in advance an angle .theta. between a workpiece plane (WPL) and a straight line (SL) connecting an approach starting point (P.sub.A) and a cutting starting point (P.sub.i), and a distance dz between the approach starting point (P.sub.A) and the cutting starting point (P.sub.i) in a direction perpendicular to the workpiece plane. Coordinate values of the approach starting point (P.sub.A) are calculated using the angle .theta. and the distance dz in such a manner that a projection (SL') of the straight line (SL) on the workpiece plane (WPL) is brought into orientation with a direction of a normal line at the cutting starting point (P.sub.i) on a curve (OLC) of the external shape. A tool (TL) is positioned at the approach starting point (P.sub.A) in a rapid-traverse mode, and the tool is subsequently moved to the cutting starting point (P.sub.i) in a cutting-feed mode. Thereafter, cutting is started.

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： A tool path drawing method which facilitates confirmation of the movement of a tool associated with three-dimensional machining, comprising steps of drawing, for example, a cylindrical workpiece figure (1) in a perspective view on a display screen (25a), in accordance with workpiece configuration data originated on the basis of an input part program statement as a figure definition statement, and displaying a YZ coordinate system, drawing a tool path (7) associated with machining on the workpiece peripheral surface on the display screen in accordance with NC data originated on the basis of an input part program statement as a motion definition statement, and at the same time, drawing another tool path (8), obtained by developing the foregoing tool path on the YZ plane, on the same display screen. An operator can easily confirm the movement of the tool with reference to both the tool path (7) based on the machining conditions and the tool path (8) based on a machining drawing.

摘要： Any hole shape pattern (HPT) and a machining procedure thereof are specified in dialog fashion and these are registered in a hole-type file (FLD) as a single item of hole-type data. In a case where the registered hole type is designated by a keyboard (14) in the creation of NC data for hole machining, an automatic programming unit (11) causes a dialog screen conforming to the hole type to be displayed on a CRT (13). Hole shape dimensions and tools used in each machining process are specified, and NC data for hole machining is created based on this data.

摘要： A prompt (MEQ) which indicates whether a machining end-point is (i) a point which coincides with a machining starting point, (ii) a point a predetermined amount .DELTA..alpha. past the machining starting point, or (iii) a point a predetermined amount .DELTA..alpha. short of the machining starting point is included on a dialog screen (DIM) and machining end-point information is entered from a keyboard (12). In response, a processor (11a) of a system main body (11) automatically computes coordinates of the machining from the machining end-point information, the machining starting point and path data, and creates NC data for arriving at the machining end-point along a path specified by the path data.

摘要： A method for defining a profile in an automatic programming system containing previously designated figure elements. Only figure elements which intersect a designated starting point are provided for selection in defining a profile element. Upon selection of a figure element, only points which intersect the figure element along the direction selected are provided for selection of the endpoint of the profile element. Once the starting point and endpoint are selected, the profile element is stored as part of the profile. The endpoint is made a new starting point and the process is repeated until the endpoint selected is the original starting point, at which time the profile has been completely defined.

摘要： When a figure element (S.sub.1) of a profile (A.sub.0) displayed on a CRT is revised to a figure element (S.sub.1 '), a processor causes a revised profile (A.sub.0 ') that does not include corner shapes (E.sub.1, E.sub.2) to be displayed on a display screen and subsequently inserts the corner shapes (E.sub.1, E.sub.2) in the revised profile (A.sub.0 ') in order one at a time. If an error is generated at this time, or in other words, if it becomes impossible to insert a corner shape, a message (M.sub.1) relating to the dimensions of the corner shape (E.sub.1) at which the error has occurred is displayed on the display screen CRT to make revision possible, and the corner shape (E.sub.1) at which the error has occurred is displayed in a color different from that of the other portions of the profile. By revising the corner shape (E.sub.1) at which the error occurred, the revised corner shape is inserted in the new profile (A.sub.0 '), which is displayed.

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.
