    摘要: A machining process determination method in automatic programming for automatically creating NC data for a lathe. The method includes storing machining processes in a memory in a machining sequence, reading the previously stored machining processes out of the memory in order after entry of a blank profile (BP) and part profile (PF); automatically discriminating based on the blank profile and final part profile whether the read machining process is needed to obtain a final part; when it is not required, performing identical discrimination processing upon reading the next machining process out of the memory, and when it is required, determining a cutting domain (A1, A2, A3) and cutting direction of the machining process; and thereafter creating NC data upon reading subsequent machining processes out of the memory and performing identical processing.

    摘要: A numerical control machining method and apparatus wherein a workpiece (101) is machined on the basis of curved surface data defining a curved surface. In the numerical control machining method and apparatus, a first boundary surface (103) serving as an upper limit and a second boundary surface (104) serving as a lower limit are respectively entered as inputs. A determination is made whether a tool lies in an upper part with respect to the first boundary surface (103), between the first and second boundary surfaces, or in a lower part with respect to the second boundary surface (104), and only the curved surface (CA.sub.1) enclosed by the first boundary surface (103) and the second boundary surface (104) is machined on the basis of the curved surface data. Then first and second boundary surfaces (103, 104) are moved downwards by predetermined values and the tool is moved by rapid traverse to a position (P.sub.12) corresponding to the first boundary surface (103'). After the completion of the machining of the curved surface (CA.sub.1) enclosed by the first and second boundary surfaces the next cutting operation is started from the position (P.sub.12).

    摘要: A numerical control method for controlling a numerical control device and prereading the numerical control data in a succeeding block during the execution of numerical control in accordance with the current block. A plurality of line segments, each specified by a block of numerical control data, approximate a curve. When the length of a line segment is less than a prescribed length (defined by required machining precision), control of movement of a member such as a tool based on the data specifying said line segment is skipped. This eliminates intermittent tool movement, improves machining precision, and prevents damage to the machine tool.

    摘要: A method and apparatus for creating numerical control data by entering coordinates which specify points on a drawing placed on a tablet. A minimum reading distance is preset at the time that coordinate values of points are to be entered from the tablet. This is followed by entering the coordinate values of prescribed points on the drawing by designating the points at random using a coordinate designating device. The coordinate values of the designated point are generated each time the coordinate designating device travels a distance equivalent to the minimum reading distance, or sampling pitch, as the device is moved continuously along a graphic appearing on the drawing. Then, numerical control data is created by using the generated coordinate values. Numerical control data approximating straight line segments can be readily created, even for curves other than straight lines and circular arcs, by setting the sampling pitch interval to a suitable value.

    摘要: A graphic form or figure drawn on a drawing and larger than the read-out area of a tablet is divided into graphic patterns which are successively read by displacing the drawing. The extent to which the drawing is displaced is recognized, and graphic data read before and after the drawing is displaced is converted into data on one coordinate system and entered as inputs. For entering the graphic data, two points are specified on the drawing, and the coordinates of the specified points prior and subsequent to displacement of the drawing are read and stored in first through fourth registers. The stored coordinates and the coordinates of points on the figure are entered into a coordinate transformation unit which effects arithmetic operations of coordinate transformation.
