OBJECTIVES AND SCOPE OF THE PROJECT

Objectives • To investigate the influence of coated tool on machining performance and compare with the non-coated tool. • To optimize processes parameters like voltage, electrolyte concentration, duty factor and tool rotation. • To develop and simulate a model for tool wear rate. Scope • This project will investigate the effect of a titanium coated tungsten carbide twist drill bit in ECDM Process for tool wear rate, material removal rate, heat affected zone, radial overcut by conducting various experiments and also evaluate the optimum parameters by ANOVA for machining of borosilicate glass and verify them with a simulated model.
