    摘要: A method and apparatus for specifying a three-dimensional curve having steps of entering data specifying a first projection curve (CV.sub.1) and a second projection curve (CV.sub.2) is obtained when a three-dimensional curve (31a) is projected onto two adjacent planes (e.g., an XY plane and a YZ plane) in a rectangular coordinate system. The method also includes finding coordinate values (a.sub.i, b.sub.i) of an i-th (i=1, 2 . . . ) partition point P.sub.i from among partition points partitioning the first projection curve (CV.sub.1) into a number of line segments and finding coordinate values (b.sub.i,c.sub.i) of a point Q.sub.i on the second projection curve (CV.sub.2) having a coordinate value b.sub.i on a common axis (Y axis) among coordinate axes of the two adjacent planes. The three-dimensional curve (31a) is specified by a collection of points (R.sub.i) having the three-dimensional coordinate values (a.sub.i, b.sub.i, c.sub.i).

    摘要: A method of controlling a comb-cutter lathe in which one face of a tool rest (TBS) is provided with two or more juxtaposed tools (TL1, TL2) for subjecting a workpiece (WK) to machining by using: (1) predetermined tools in succession, (2) part dimensions, (3) a tool selection sequence, (4) a machining start location for each tool, and (5) mounting dimension information measured from a reference point on the tool rest to a distal end of each tool. Machining is sequentially performed based on this information by predetermined tools at machining locations (P.sub.5 -P.sub.4 -P.sub.3 -P.sub.2 -P.sub.1 ; P.sub.6 -P.sub.7 -P.sub.8 -P.sub.9 -P.sub.10) assigned to the tools, and after machining is completed by a first tool (TL1), the tool rest (TBS) is moved to position the next tool (TL2) at a machining location and machining is performed by that tool. The method includes moving the tool rest along a Z axis to a point P.sub.r at which none of the tools (TL1, TL2) will contact the workpiece (WK) when the tool rest (TBS) is moved in a direction (X-axis direction) at right angles to the longitudinal direction (Z-axis direction) of the workpiece, and thereafter moving the tool rest along the X axis to a point P.sub.t at which an X-axis position of a selected tool coincides with an X-axis coordinate value of a position at which machining is to be started by the selected tool, and thenforth performing machining using the selected tool.

    摘要: A curved surface generation method well-suited for application to the preparation of a numerical control tape used in the numerically controlled machining of a three-dimensional body such as a three-dimensional mold. The surface creation method includes steps of defining, on a first section curve or reference curve of a three-dimensional curved body, a point Pi (i=1,2 . . . ) which corresponds to a point Qi (i=1,2 . . . ) on a second section curve or reference curve, and generating an intermediate section curve in accordance with the established correspondence. A curved surface is created by collecting a plurality of the intermediate section curves together. Accordingly, the invention raises the degree of freedom with which a curved surface is created, and enables the accurate creation of a curved surface featuring subtle changes, allowing the precise machining of a three-dimensional body.

    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: A program for operating a numerical control machine tool written in problem oriented language is translated into machine oriented language through the use of the present NC tape producing system. The present system has a mini-computer mounted in a desk type cabinet, which has also a printer, an input tape reader, an output tape puncher, a key board, and a mini-board panel, each connected to said mini-computer. The mini-board panel is covered with the mini-board sheet indicating the roles of keys under the mini-board sheet. The system is automatically initialized just by turning on a power switch, or pushing a load key, and the program for operating the mini-computer itself is automatically loaded in the memory of the mini-computer through said input tape reader. Thus, the operation of the system is very easy. A problem oriented source program is applied to the system through the input tape reader, translated by the mini-computer to a machine language program, which is in turn obtained from said output tape puncher.
