Automated profiling of tool electrode in electrochemical pulse machining

Compressor blades are the most complex and critical parts of a gas turbine engine. It is driven by the cost of their production, as well as the requirements in terms of reliability and service life. A promising method for manufacturing the blades is a pulse electrochemical machining (ECM), the main advantages of which are the lack of power and thermal effects on the treated surface, the longevity of the tool, at low values of roughness parameters when working at high current densities in high-precision copy form and stability during operation of the process at a sufficiently small interelectrode gaps. In this paper we have set out the principles for the implementation of the model applied to the electrochemical shaping pulse echo that will deliver engineering simulation methodology for processing and profiling tool electrode in a real production. In solving the problem of electrochemical formation, taking into account the factors influencing the process was proposed algorithm describing the process of pulse echo, which was based on the use of a numerical method for sample processing in time and space. This algorithm will automate profiling tool electrode during pulse electrochemical treatment.
