Abstract
Disclosed is a feedrate controlling method and apparatus for controlling a wire-cutting electric discharging machine (WEDM) to operate at optimal feedrate. In the apparatus, a discharge frequency counter is used to count the frequency of normal discharge and the frequency of abnormal discharge, from which two performance indexes: stability percent (STB) and efficiency percent (EFF) are obtained. These two performance indexes allow the apparatus to use a decision table to obtain an optimal feedrate variation used to change the current feedrate so as to operate the WEDM with maximum stability and efficiency.
