    摘要: A method and an apparatus for controlling spindle speed are disclosed. When the speed ranges of respective first, second and third gear ranges are selected in advance so that speed ranges corresponding to neighboring gear ranges partially overlap one another, and the gear range conforming to the commanded spindle speed is selected for rotating the spindle at the commanded spindle speed, it is decided whether the commanded spindle speed belongs to the currently selected range, no gear change is made if the decision is affirmative, and the gear range to which the newly commanded spindle speed ' belongs is found if the decision is negative, the gear range being switched to the gear range thus found.

    摘要: A method and apparatus for system creation in which a processor (10) exchanges information with input/output units (2a, 2b) in accordance with a control program stored in a memory (11). The control program is stored in a memory in the form of a basic program (11m) and plural optional programs (11 a, 11 b, 11 c), and the processor (10) discriminates the hardware complexity level of the connected input/output units (2a, 2b) and decides which of the plural optional programs (11a, 11 b, 11 c) are to be executed.

    摘要: A numerical control method for application to a numerical control device for prereading the numerical control data in a succeeding block during the execution of numerical control. 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 in conformance with a 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. a decline in machining precision, as 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 coordinate designating means, generating the coordinate values of whatever point is being designated by the coordinate designating means each time said means travel a distance equivalent to the minimum reading distance as said means is moved continuously along a graphic appearing on the drawing, and creating numerical control data by using the 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 a sampling pitch interval to a suitable value.

    摘要: A figure on a drawing DR placed on the read-out area TRA of a tablet is entered through a coordinate designating device by designating a plurality of points on the drawing, and at the same time the origin of the drawing coordinate system is set and entered. To carry out the setting and entry of the coordinate system origin, a first point Pt on the drawing is designated by the coordinate designating device to enter the coordinates of the first point Pt in a tablet coordinate system, and the coordinates of the designated first point Pt in a numerical control data coordinate system are entered by a keyboard or the like to set the origin of the numerical control data coordinate system. The invention provides a method and apparatus for effecting the foregoing setting of the coordinate system origin. The origin of the numerical control data coordinate system can be easily established, and can be set and entered even when the origin is located outside the read-out area TRA of the tablet.
