Research on Precision EDM Technology for Closed Integral Component of Difficult-to-Cut Material
It is great difficult to manufacture a closed integral component due to its poor processing accessibility caused by complicated structure of air flow channel between two blades
especially the large bending and twisting degree in the channel as well as its component materials of high strength alloy. To solve this problem
several key technologies of electrical discharge machining (EDM) are discussed
such as division of the processing zone among the blades
shaped electrode and its motion trajectory design
process benchmarking unification
process parameters selection and optimization
simulation of EDM process and so on. On top of this
typical closed integral components are studied and manufactured. It is shown from the experimental results the above-mentioned technologies enable numerical control EDM technology to realize precise and reliable manufacture of closed integral components.
