The challenge of recent machining industries is reduce lead time and increase production rate in order to maintain their competitiveness. This paper investigates the machinability of mild steel in turning process perform on conventional lathe machine. Twoparameters like tool rake angle and feed are varied to investigate their effect on material removal rate. An attempt has been made to model th...

In this study, turning operation of Monel K500 copper-nickel super-alloy was evaluated. Ceramic cutting tools with two different cutting noses (conventional and wiper) were utilized. At first, the experimental tests were designed by using central composite design method. After implementation of the tests, the statistical models for output data (surface roughness, cutting force, and flank wear) ...

Chatter vibrations are present in almost all cutting operations and they are the major obstacles in achieving desired surface finish. Chatter vibrations are the self excited vibrations, which has an adverse effect on surface roughness, dimensional accuracy of the machined components. This paper investigates the occurrence of regenerative chatter vibrations in centerless bar turning operation. T...

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

Dictyostelium discoideum slugs migrating in the absence of external stimuli tend to continue migrating in the original randomly 'chosen' direction. Spontaneous deviations from the starting direction accumulate with time at a rate that measures the 'physiological noise' in the slugs' steering mechanism. Most of the spontaneous turning signals arise in the transduction chain 'downstream' of the c...

Abstract In this study, the effects of cutting speed, tool geometry, and machining parameters on surface roughness forces in turning Nilo 36 superalloy have been investigated. An experimental design process was made with Taguchi technique. way, optimum values were estimated a small number experiments. The grey correlation analysis method used to determine best parameter levels plausible factors...
