Optimization of surface roughness and cutting temperature in high-pressure coolant-assisted hard turning using Taguchi method

摘要: In this article, the effects of material hardness and high-pressure coolant jet over dry machining are evaluated in respect surface roughness cutting temperature using Taguchi L36 orthogonal array. The experimental data was analyzed empirical cumulative distribution function box plot with to environment. Afterward, optimization quality responses is performed signal-to-noise ratio. As part optimization, “smaller better” adopted as principle; design experiment used for parameters orientation, analysis variance determining control factors. For present studies, three types hardened steels (40 HRC, 48 56 HRC) were turned by coated carbide insert at industrial speed–feed combinations under both jet. Depth cut, being a less significant parameter, kept fixed. found successful reducing temperature, roughness, tool wear. statistical showed that work most factor roughness. However, other variables exerted somewhat similar contribution, while environment demonstrated crucial role. confirmation tests 15.85 0.28 % error predicting respectively.
