Processing Properties

The short electric arc machining technique is a new type of strong current processing method, which has many advantages, especially for difficult-to-machine materials, such as no cutting force, small cutting chips, easy to chip removal, high processing efficiency and so on. In this paper, the electric arc processing cutting performance of two typical difficult-to-machine materials, titanium alloy and high-temperature alloy, was studied by electric machining cutting experiment to analyze the influence of arc processing on the properties of materials. Using the designed electric arc machining system, the effect of electrical processing parameters on processing properties was discussed. Furthermore, the surface layer hardness and materials metallurgical structure were detected to study the change of material internal organization and the effects on material properties change, which provide the corresponding theoretical analysis basis for arc machining of difficult-to-machine materials. Experimental results show that the titanium alloy and high-temperature alloy have small heat affected zone and hardening layer after electric arc processing, which could meet the requirement of subsequent machining to obtain a good surface quality.

Experimental results of Ti-6-2-4-2S, Ti-6-4 and Ti-5-5-5-1-1 are detailed in this paper with conventional surface grinding using SiC abrasive under dry conditions. Measurements of grinding forces, surface topography and metallurgical structure of ground surface were taken to investigate the grinding mechanism of these materials. The results showed grinding force ratios to these materials were between 1.35 to 2.25 at all material remove rates, but the specific energy to Ti-5-5-5-1-1 and Ti-6-2-4-2S were little higher than Ti-6-4. Evaluation of ground surface topography indicated they were visually free of crack and burn. At the same grinding parameters, Ti-5-5-5-1-1 had the maximum depth of heat-affected zone because of its poor high temperature properties.
