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： A CNC process for displacing a movable member along a path on an intricate surface in a three-dimensional coordinate system is disclosed in which the surface is divided into a plurality of elementary characteristic regions each individually definable as one of different geometrical categories such as toroidal, spherical, cylindrical and planar surfaces. The process comprises establishing a general equation for each of these categories and storing the established general equations into a memory unit for a computer. Data required to adapt each of the stored general equations to a corresponding one of the characteristic regions in the three-dimensional coordinate system are inputted into the computer to reduce the general equations to their respective specific equations in which no more than three coordinates are variable. A sequence of incremental two-dimensional positions defined in the system by first and second coordinates thereof are inputted into the computer to allow it to compute, for each position on the path, the value of the third coordinate from the first and second coordinates and the specific equations, thereby determining the path along which the member is moved.

摘要： A method of controlling electrical discharge machining in which a machining discharge is initiated and the particular geometric characteristic of the site of the discharge is ascertained by detecting at least one of the gap variables over a predetermined checking period of the discharge and evaluated with respect to a reference value. A parameter of the discharge, e.g. duration and/or current magnitude is established at a particular value preset to correspond to a particular geometric characteristic and the discharge is terminated in accordance with the regulated parameter.
