The main objective of this article is to perform the turning operation on an EN36B steel work-billet with a tungsten carbide tool, to study the optimal cutting parameters and carry out an analysis of flank-wear. Experimental and simulation-based research methodology was opted in this study. Experimental results were obtained from the lab setup, and optimisation of parameters was performed using RSM (response surface methodology). Using RSM, cutting-tool flank-wear was optimised, and the cutting parameters which affect the flank wear were determined. In results main effect plot, contour plot, the surface plot for flank-wear and forces (Fx, Fy and Fz) were successfully obtained. It was concluded that tool flank-wear is affected by depth of cut, and that flank-wear generally increases linearly with increasing cutting-speed, depth of cut and feed-rate. To validate the obtained results, predicated and measured values were plotted and were in very close agreement, having an accuracy level of 96.33% to 98.92%. 相似文献

The aim of the present systematic review was to summarise and evaluate the studies comparing the role of contracted endodontic cavities (CECs) and traditional endodontic cavities (TECs) in terms of instrumentation efficacy. The present systematic review comprised of a search of the online databases of Cochrane, PubMed, Google Scholar and grey literature. The articles which were pertaining to instrumentation efficacy in contracted and traditional endodontic cavities were selected based on the PRISMA checklist. Out of the 660 articles which were obtained, irrelevant articles were excluded and a total of 17 articles were selected for this systematic review which assessed the instrumentation efficacy. Eleven studies compared the volume of dentin removed and canal transportation ability. Four studies compared the pulp debridement, and two studies compared the anti-bacterial efficacy between the two groups. The extrusion of debris between the groups was compared by one study. Out of the 17 studies included, 11 studies proved that contracted endodontic cavities negatively impacted the instrumentation efficacy. Hence, the data suggest that the traditional endodontic access cavities have better results when comparing the instrumentation efficacy. 相似文献
