Machining systems and methods

A Method and machine tool for compensating a wear of an electrode that machines a workpiece. The method includes selecting a current pocket from plural pockets of the workpiece; updating a wear compensation to be applied to the electrode for the current pocket based on wear compensation of a previous pocket, where the previous pocket is adjacent to the current pocket; and applying the updated wear compensation to the electrode for machining the current pocket.

Method for compensating a wear of an electrode

An electroerosion control system includes a general CNC controller being configured for controlling a general CNC machine process, a power supply for energizing a tool electrode and a workpiece to be machined, an electroerosion controller electrically connecting with the power supply for controlling an output of the power supply, and adaptively and electrically connecting with the general CNC controller for communication thereof, and a sensor sensing real-time status information of a working gap between the tool electrode and the workpiece and for sending said real-time status information to said electroerosion controller. Said electroerosion controller automatically controls the electroerosion machining process through the general CNC controller according to the real-time status information of the working gap.

Electroerosion machining system and method for electrode wear compensation

An apparatus and method for adapting a CNC milling machine for electroerosion machining. The apparatus includes a tubular electrode on the distal end of an adapter shaft. A tool holder on the proximal end of the adapter shaft is mountable in the chuck of a cutter spindle in the milling machine. The adapter shaft is rotatably mounted within a bearing and an electrical brush contact subassembly, both of which are supported by a bracket. The bracket is attached to the milling machine but insulates it from the tool electrode. The bearing supports the adapter shaft in alignment with the CNC spindle. An electrical power supply energizes the electrode and the workpiece for electroerosion in a gap between them. Electrolyte is circulated through the spinning tool electrode during operation. The CNC computer is configured to operate the machine, power supply, and electrolyte flow for electroerosion machining.
