Background:
Micro-Electrical Discharge Machining (EDM) milling is widely used in the
processing of complex cavities and micro-three-dimensional structures, which is a more effective processing
method for micro-precision parts. Thus, more attention has been paid on the micro-EDM milling.
Objective :
To meet the increasing requirement of machining quality and machining efficiency of micro-
EDM milling, the processing devices and processing methods of micro-EDM milling are being improved
continuously.
Methods:
This paper reviews various current representative patents related to the processing devices
and processing methods of micro-EDM milling.
Results:
Through summarizing a large number of patents about processing devices and processing
methods of micro-EDM milling, the main problems of current development, such as the strategy of
electrode wear compensation and the development trends of processing devices and processing methods
of micro-EDM milling are discussed.
Conclusion:
The optimization of processing devices and processing methods of micro-EDM milling are
conducive to solving the problems of processing efficiency and quality. More relevant patents will be
invented in the future.
