A method and a device are for controlling multiple machining processes in a die-sink erosion machine with several identical or different electrodes (R , R , R , R ), whereby the machining sequence of the machining processes and the electrode used for each machining process are determined by providing the following criteria: a) predefining priorities of workpieces to be machined, of a group of machining procedures, of individual machining jobs (ARB), of work cycles (AZ) and/or work steps (AS) of a machining job; and/or (b) predefining the life span or wear limit of the electrodes used for the individual machining jobs, work cycles or work steps. The overall machining on the die-sink erosion machine is performed with consideration of the determined machining sequence.

Method and device for controlling a die-sink erosion machine

A method and a device for controlling a number of machining processes on a machine tool with the help of a control device ( ) that controls at least one tool for performing said number of machining processes under the direction of a control program, whereby the control program is created using a description of the tools required for performing the machining processes, and whereby the data for describing the tool are hereby divided in memories ( ) of the control device ( ) into: (a) abstract tool data for describing a standard tool (V , V ), and (b) specific tool data for correcting and/or adapting the abstract tool data to the actually used tool (R , R ) or to machine-specific characteristics, whereby the tool description in the control program is obtained by linking the abstract tool data with the specific tool data.

Method and device for controlling a machine tool, in particular, a die-sink erosion machine

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.
