In a manufacturing method of a resin composite plate for manufacturing a resin composite plate by heating under pressure a resin sheet group having a plurality of fiber-reinforced thermoplastic resin sheets stacked together, and thereby integrating the resin sheet group into one resin composite plate, the fiber-reinforced thermoplastic resin sheets each containing fibers arranged in one direction, the resin composite plate having a desired thickness is manufactured by stacking the plurality of fiber-reinforced thermoplastic resin sheets having different thickness.

Method of generating robot control axis position data

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.

Robot control system

There is provided a numerical control unit having a processor (102a), a control program memory (102b), a memory (102c) for storing files, and input means (102d) for accessing the files. The processor (102a), in accordance with the control program, processes externally entered control data to numerically control a machine connected thereto. The arrangement is such that the name of a file to be protected is stored in the memory (102c) of the numerical control unit and, the name of an object file is compared with the protected file name in the memory (102c), when a modification command and the name of the object file are entered from the input means (102d). Processing for modifying the file is executed, on the condition that there is a processing confirmation input from the input means (102d), when the object is a file protected file.

In an apparatus wherein a memory is subdivided into plural storage areas, and predetermined data are adapted to be written into respective ones of the storage areas, a method of reconfiguring the storage areas of the memory. The leading addresses of the respective storage areas and the sizes of blank portions of the respective storage areas are stored while it is discriminated whether a blank portion exists in a predetermined one of the storage areas. When there is no blank portion or substantially no blank portion in the predetermined storage area, the blank portions of the remaining storage areas are reduced in size on the basis of the leading addresses and the sizes of the blank portions. The predetermined storage area is enlarged by an amount equal to the amount of blank portion reduction effected in the remaining areas.

Automatic welding machine torch movement control system

There are provided a tracing control apparatus (1), a numerical control apparatus (2), and switching circuits (3X, 3Y, 3Z) for switching and transmitting selectively control instructions from the tracing control apparatus (1) and the numerical control apparatus (2), to a three-axis driving means for the tracer controlled machining (4) and a three-axis driving means for the numerically controlled machining (5) in accordance with selection signals. A numerically controlled machining and tracer controlled machining selection signal (S.sub.C) is used as one of the selection signals besides a tracer controlled machining selection signal (S.sub.A) and a numerically controlled machining selection signal (S.sub.B). When the numerically controlled machining and tracer controlled machining selection signal (S.sub.C) is selected, the three-axis driving means for the tracer controlled machining (4) is controlled by the tracing control apparatus (1), and the three-axis driving means for the numerically controlled machining (5) is controlled by the numerical control apparatus (2), independently. As a result, it is possible to perform the preparation for the tracer controlled machining or the conversion of the tracer controlled machining data into digital information, simultaneously, with the numerically controlled machining.
