A method for controlling an electric discharge machining process, wherein a tool electrode is moved relatively to a workpiece with a working gap distance, wherein the process includes a current and at least one previous erosion cycle, the current and the previous erosion cycle each being divided into predetermined time intervals each including at least one discharge pulse, wherein similar working gap conditions are present within a time interval of the previous erosion cycle and of the current erosion cycle, and wherein subsequent erosion cycles are separated by a process pause cycle.

Method and apparatus for controlling an electric discharge machining process

Disclosed are a method and a device for suppressing vibrations () in an installation comprising an actuator () for actuating a flap () or a valve () used for metering a gas or liquid volume flow (), especially in the area of HVAC, fire protection, or smoke protection. Vibrations () of the flap () or valve () caused by an unfavorable or wrong adjustment or configuration of the controller and/or by disruptive influences are detected and dampened or suppressed by means of an algorithm () that is stored in a microprocessor (). Said algorithm is preferably based on the components recognition of vibrations (), adaptive filtering (), and recognition of sudden load variations ().
