WITHDRAWN: The effect analysis for the nano powder dielectric processing of ti-6242 alloy is performed on wire cut-electric discharge

Abstract The present paper focuses on the titanium alloy wire electric discharge unit. It can be considered as an attempt to develop models of response variables, Using a different liquid, one of which is nanoparticle (AL2O3), using a ratio of (2 mg) and the function of comparison in both cases they are; the rate of material removal, using the response surface methodology in the wire electrical discharge machine process. The pilot plant is based on the Minitab 18 concept, and the study conveys the six key parameters. ANOVA was applied to evaluate the value of the advanced model; the test results support the validity and appropriateness of the advanced RSM model. Ultimately optimal parameter settings are improved.

The Effect of Notch Processing on Fracture of High-Carbon Steel (C70S6)

The effect of starting notch machining methods on fracture splitting of connecting rod was studied by axial tensile tests with single edge notch. The axial tensile specimens were made of the high carbon microalloyed steel (C70S6) which is now most widely used by the connecting rod of fracture splitting. The single edge notch of axial tensile specimens were respectively machined by laser notch、wire cut electrical discharge and broaching. The notch tip plastic deformation of specimens was compared by the fractography. The experimental results indicate that the specimens with laser notch can be fractured by the smallest axial tensile load which is respectively about 20% and 30% smaller than the fracture load of the specimens by wire cut electrical discharge and broaching. Considering the rich micro-local crack transformation hardened zones around the notch by laser the paper present the equivalent critical stress intensity factor KIcL which can be used to calculate the fracture load with laser notch.
