摘要： A numerically controlled positioning system for positioning a movable member, employing serial signal processing circuits having circulating registers for receiving discrete input signals representative of a desired position of the member and for receiving feedback signals of actual position of said member, in which, arithmetic combinations of the input signals, compensated as required for position offset, and the feedback signals, provide control signals for positioning the member.

摘要： When the movement of a machine element is guided by a multi-axial, numerically controlled machine through the selection of interpolation points which are calculated and stored off-line, a tool-radius correction is rendered possible. This occurs because correction interpolation points are calculated on the basis of interpolation points and thus, with the least possible expenditure of time, a new trajectory curve can be generated, with which the radius changes are considered. In addition, a change in feedrate can be achieved through the selection of override values by placing fine interpolation points between two interpolation points at a time.

摘要： A numerical-control (NC) method and system for machining a desired three-dimensional contour in a workpiece with an axial tool, e.g. a rotary milling cutter or electroerosion electrode, formed at its axial end with an active machining surface which is spherical about a center intersected by the axis of the tool. According to the invention, numerical coordinate values for the positions of this center of the tool to be displaced relative to the workpiece need not to be preprogrammed and stored on a record medium. Rather, the numerical coordinate values for a series of prescribed points on the desired contour, together with the angular values defining an imaginary line normal to the contour at each of these points are simply programmed and stored on such an NC tape or like medium, and a numerical datum for a constant value substantially equal to the radius of the sphere is keyed in into a computing device arranged between a tape reader and drive units for computing from the data reproduced from the NC tape and the keyed-in datum, for each of the prescribed points, the three-dimensional coordinate values of the position of the center of the sphere. The computing device is associated with a drive control unit for producing from the computed numerical coordinate values, command signals to operate the drive units so that the workpiece and the tool are relatively displaced to allow the desired contour to be progressively developed in the workpiece.

摘要： The coordinate values (X, Y, Z) for the position of the front end of a tool and the vector (I, J, K) of the axial direction of the tool are read in from a command tape by a tape reader. Using these values and a tool length l set by a dial or the like, a movement data calculation circuit calculates the orthogonal coordinate values (x, y, z) of the position Q of the center of rotation of the tool and spherical coordinate values (b, c) indicative of the position of the rotational angle of the tool. After these coordinate values are converted into pulses for moving the tool in the respective axial directions by a pulse distribution circuit, servomotors are driven by the pulse signals and through servo circuits so as to move the tool or a table to a desired machining position.
