摘要： A method of precision electric-discharge machining carried out in apparatus of moderately high precision and stability with an electrode in the form of a wire. The object is a surface as smooth as the surface that can be obtained with the more expensive very high-precision apparatus. The contour of work that has already been roughed out at least once is accordingly exploited as a geometrical reference for at least one finishing cut. The gap is maintained constant by fine adjustments.

摘要： A coarse interpolator is adapted for use in a numerical control system for performing path interpolation calculations for the control of highly dynamic processes. These processess have different path contour geometries wherein a vector having a length L connects in linear form a first point P1 to a second point P2. These points are located in three dimensional Cartesian space having axes X, Y, and Z, Length L has Cartesian components X, Y and Z and is subject to an angular rotation C about the z axis. The interpolator responds to a group of predetermined vector lengths, starting with the maximum length, in order to calculate the path elements L, X, Y, Z and C for the maximum length vector. A path error E is then determined for the path elements so calculated. The error E is then compared with a praedetemined maximum error value. If the error E does not exceed the maximum value, the calculated path elements are outputted. If the error E exceeds the maximum value, the path elements for the vector which has the length next shorter to the vector of maximum length are then calculated. These operations are repeated until the path elements calculated for a vector result in a path error which does not exceed the maximum value and these path elements can be outputted. The distance between the outputted path elements and the end point of the path contour is then determined and the coarse interpolator stops interpolating when the distance has a zero value.

摘要： A numerical control system performs path interpolation calculations for the control of highly dynamic processes having different path contour geometries wherein a vector having a length L connects in linear form a first point P1 to a second point P2. These points are located in three dimensional Cartesian space having axes x, y, and z. Length L has Cartesian components X, Y and Z and is subject to an angular rotation C about the z axis. The system also has process parameters S and K wherein S is an address identifying the parameter to be modified and K identifies the modified parameter value. A coarse interpolator outputs the path elements L, X, Y, Z and C and the parameters S and K between path increments as course interpolations which are a function of the path contour geometry but are independent of time frame. A fine interpolator having an intermediate memory is connected downstream from the course interpolator. The fine interpolator outputs the path elements and parameters as fine interpolations. The intermediate memory receives, for intermediate storage and subsequent processing, the course interpolations from the course interpolator. There is no joint fixed grid frame for data exchange between the two interpolators. Control means operates in time independence from the coarse interpolator and controls the fine interpolator with its memory to perform the fine interpolation steps and the outputting of parameters S and K in real time.

摘要： The invention relates to a method and generator for generating a time sequence of EDM pulses having a predefined ignition voltage for electrical discharge machining. An AC voltage is generated from a DC voltage, furnished by a bipolar current source. The AC voltage is applied to an isolating transformer disposed between the bipolar current source and the spark gap. A first pulse capacitor is charged by the bipolar current source to a voltage corresponding to the ignition voltage. The ignition voltage provided by the isolating transformer is switched with a selected polarity to the spark gap.

摘要： The invention pertains to a method and a device for die sinking and wire-cutting workpieces by means of electrical discharge machining. A machine frame (10) as well as a worktank (9) and a lower guide head (5) form a stationary unit referred to the main axis directions X, Y. The workpiece (2) is immersed in the worktank (9) and moved in the horizontal plane by means of the X/Y main axis drive (14). An upper guide head (4) also forms part of the stationary unit or can be moved by means of a Z drive (16) and/or a U/V drive (15). The lower guide head may also be designed such that it can be vertically moved by means of a lower Z drive (17).
