Research On Mechanism Of Short Arc Machining

Since the Short-arc Processing technology has been appeared, and the short arc processing machine tool was successful developed, after a few years of development, such techniques and machine tool have been widely used and recognized in the enterprises.The Short-arc Processing technology enriches the field of special processing of the type of technology, it provides an efficient processing technology as high hardness, high strength, high toughness of the conductive material. However, it is in the growth stage of this technology and it is still not fully mature. Mainly in the processing mechanism is not thorough, making the development of the field in finishing is limited.Therefore, the mechanism of the short arc process was researched in depth in this dissertation. Through the theoretical knowledge of EDM arc processing technology and the short summary of the experimental data, hoping to explore some rules of the short arc process. Based on this, this dissertation has completed following contents:The current mainstream of the various types of special processing world had been studied and researched, and discharge and arc discharge machining principle theory were researched too. It summed up the rules and characteristics on the special processing method for processing difficult materials, and it derive the same area belonging to the short arc discharge machining processing Laws and mechanisms, and this provided a methodology for the mechanism of the short arc process research.It has designed and completed a short arc current signal processing technology acquisition system, and has verified the current short arc process variation. This has designed and completed a short arc difficult to machine materials, machine tools for cutting of the trial process trials to test for the effective removal of difficult materials processing.It has designed and completed the orthogonal tests about seeking to influence the short arc machining efficiency and quality of the non-electric parameters.It has designed and completed a mixture of liquid medium on the stability of the short arc machining experiment. With high-speed video camera through the observation of the short arc process of the experiment, visually verify that the short-arc discharge process in the discharge channel characteristics.
