    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: 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: The invention relates to a method and device for electrical discharge machining (EDM) a workpiece by means of a train of machining pulses. During the machining time the machining pulses are applied to the working gap between workpiece and electrode, whereby an electrical parameter of the current machining pulse applied to the working gap is sensed, from which at least one characteristic value is derived. This is compared to a reference value, and depending on the result of the comparison, actions are initiated. The reference value is captured on the basis of at least one earlier machining pulse. The machining time is divided in time into sensing intervals during which reference values are captured from the applied machining pulses and into machining intervals during which no reference values are captured from the applied machining pulses. The sensing intervals comprise first machining intervals after implementation of a jump motion of the electrode in the working gap and/or second machining intervals after application of machining pulses with an extended pause time.

    摘要: A method and an apparatus for controlling a spark erosion process between a workpiece and an electrode for instance a microdrilling electrode, so that the erosion process becomes less susceptible to a malfunction, in that at least one process parameter is measured along a first test interval of the section to be eroded, at least one control value is deduced form the measured values, and this control value is used in a subsequent erosion interval of the section to be eroded. The control value is preferably used for controlling a suitable feed rate of the electrode. The susceptibility to malfunctions is further lessened, in that a differentiation is made between mechanical and other short circuits and in that the electrode movement is controlled differently for mechanical short circuits than for other short circuits.

    摘要: A servocontrol device for controlling a distance between an erosion electrode and a workpiece in an erosion machine calculates an error signal from an actual distance between the erosion electrode and the workpiece and a desired distance. The error signal undergoes low pass filtering, before it is used as a control signal for a drive connected to the erosion electrode to drive the latter. For optimizing the dynamic characteristics, the servocontrol device has a variable cutoff frequency, which is dependent on at least one parameter of a processing pulse supplied to the erosion electrode.
