摘要： A CAD/CAM system arranged so that a re-creation processing for a cutter path is automatically executed by a CAM system when a curved surface is modified by a CAD system. Functions for the cutter path re-creation processing are provided by utilizing a customizing function of the CAD system. In executing computation for the cutter path and in originating NC data, references for assigning the functions are previously set for the curved surface. When the shape of the curved surface is modified on the CAD side after the NC data has been created, the CAM is invoked to invoke the aforesaid functions. Perceiving this invocation, the CAM executes the cutter path re-creation processing by using machining condition data set for the unmodified curved surface, on the basis of the invoked functions. Thus, the cutter path for the modified curved surface is created immediately by the CAM when the curved surface is modified by the CAD.

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： The original planar shape or developed shape of a product to be manufactured by bending is determined using a computer-aided design system. An operator operates a tablet unit to prepare, first and second projection drawings of, e.g., an L-shaped product, projected onto two planes parallel to the outside of first and second sides of the product, with a bending line in common. The computer-aided design system displays the first and second projection drawings on a display screen in accordance with shape data which defines the two projection drawings (S1). In response to the operator picking two vertices of each projection drawing on the side of the bending line using the tablet unit (S2, S3), the processor calculates distances of movement in the X- and Y-axis directions and the rotational angle of the second projection drawing required for the alignment of the two sets of vertices (S5). Based on these calculated values and the amount of expansion or contraction of the product material accompanying the bending work, calculated in accordance with input data indicative of the thickness, bending angle, and bending direction, the processor prepares shape data indicative of the product shape prior to bending and causes the developed product shape to be displayed on the display screen (7).

摘要： A tool axis direction calculation method for determining a direction vector of the tool axis when a side is cut be a 5-axes numerically controlled machine tool. A normal vector (Ri) is determined at a dividing point (Pi) of the upper surface of a sculptured surface, and a normal vector (Si) is determined at a dividing point (Qi) of the lower surface thereof. Next, an intermediate vector (Ni) having a direction between the normal vector (Ri) and the normal vector (Si) and a size equal to the radius of a tool is determined. Offset points (Xi, Yi) are determined from the intermediate vector (Ni), and a vector (Zi) connecting the offset points (Xi, Yi) is determined as the direction vector of the tool axis. A direction vector of the tool axis closest to a generating line can be obtained, and thus a side closest to a desired sculptured surface can be cut.

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 main figure (FG1) and at least one subordinate figure (FG2) are designated, a processor (11a) obtains, a point of intersection at which a figure element of the main figure (FG1) intersects each figure element, e.g., a linear element (EL.sub.1), constituting the subordinate figure (FG.sub.2). If a point of intersection exists, the figure element (EL.sub.1) is divided at the point of intersection (P.sub.c) to generate subordinate figure elements (EL.sub.11, EL.sub.12), and an item of hidden-flag data, which is indicative of a subordinate figure element (EL.sub.12) on an inner side of the main figure, is turned on. The image of the subordinate figure element (EL.sub.2) is not displayed on the display screen. In a case where a figure element such as the figure element (EL.sub.2) of the subordinate figure (FG2) is not intersected by any of the figure elements of the main figure (FG1), it is checked to see whether a starting point (P.sub.s) of the figure element resides on the inner side or outer side of the main figure. If it is on the inner side, the item of hidden-flag data of this element is turned on and this element is not displayed on the display screen.
