Electric spark forming processing technology present situation and trend of development

Electric spark forming processing technology present situation and trend of  development

 I、Introduction

Precision metal parts As an advanced technique of manufacture important branch, the special processing technology, the electric spark machining technology, since the 20th century 40's foundations, has had been through repeatedly in particular for more than half centuries the development, has become the advanced technique of manufacture domain indispensable important constituent. Enters after in particular the human for 1990s, along with high technology and new technology and so on information technology, networking, aviation and astronautics technology, materials science technology development, the electric spark forming processing technology also faces a deeper level, the high level direction is developing. Although some traditional processing technology through own unceasing renewal development as well as with other correlation technology fusion, difficult to process the material processing domain in some (especially in mold processing domain) to display the processing efficiency higher superiority, but these technical application has been impossible to substitute for the electric spark forming processing technology difficultly to process processing domain completely and so on in the material, complex profile, mold statuses. On the contrary, the electric spark forming processing technology through profits from other processing technology the development experience, to the micro refinement, highly effective directions and so on, precision, automation, intellectualization is developing unceasingly. 

II、Electric spark forming processing technology development present situation

 Precision metal parts At present, in electric spark machining basic theory research area, because the electric discharge process itself complexity, randomness as well as the research method lack the innovation, until now not yet made the unprecedented progress. But in processing craft and control fundamental research domain, because the research results may apply directly in the production practice, therefore has become in the present electric spark forming processing engineering research a more active domain, its research hot spot mainly concentrates in the highly effective processing technology, the high precise processing technology (glassy surface processing technology), the low loss processing technology, the tiny processing technology, the non-conducting material processing technology, the electric spark surface treatment technology, the intelligent control technology (for example artificial neural networks technology, fuzzy control technology, expert system and so on) as well as aspects and so on operational safety, environmental protection. In the process unit development aspect, the present new electric spark forming processing engine bed in aspects and so on processing function, processing precision, automaticity, reliability improved comprehensively, many engine beds have had online functions and so on examination, intelligent control, modulation, no longer is in the traditional significance special processing engine bed, but looks like in the machining the numerical control engine bed even to process the center.

Precision metal parts The advanced technique of manufacture fast development and the manufacturing industry market competition aggravating proposed to the electric spark forming processing technology a higher request, simultaneously also for the electric spark forming processing technology processing theory research and the craft development, the equipment renewed has provided the new power. The next electric spark forming processing processing object will be supposed mainly to face the tradition machining not not easily to realize difficultly to process processings and so on material, complex profile, in which fine processing, the precise processing, the narrow dadoing, the deep cavity processing and so on becomes the development priorities.
