Lasers are widely used in industry as cutting tools due to ultra flexibility of the cutting conditions, obtaining high quality end product, quick set up, non-mechanical contact between the workpiece and the tool, and small size of the heat affected zone. In the present study, laser gas assisted cutting process is examined. Statistical method based on factorial analysis is introduced to identify...

In this study, two different vegetable based cutting fluids developed from refined canola and sunflower oil and a commercial type semi-synthetic cutting fluid were carried out to determine optimum conditions for tool wear and forces during milling of AISI 304 austenitic stainless steel. Taguchi L9 (3) orthogonal array was used for the experiment plan. Cutting speed, feed rate, depth of cut and ...

the influence of 0-27 g/100g of full-fat soy flour (ffsf), 31-35g/100g of water content and extrusion conditions on the textural characteristics of spaghetti were evaluated. process was performed with screw speed of 10-40 rpm and water circulating temperature of 35-70°c. this enrichment resulted in significant differences in mechanical strength and cutting parameter. based on the mixture surfac...

The present study investigates the failure mechanisms of industrial fiber materials, using a custom designed fiber cutting performance test bench. The fracture morphologies of single PA6 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be distinguished according to four distinct stages of fiber failure represented by shearing, cutting, brittle fra...

in this study, the application of gray relational analysis (gra) and taguchi method in multi-criteria process parameters selection of turning operation has been investigated. the process responses under study are material removal rate (mrr) and surface roughness (sr); in turn, the input parameters include cutting speed, feed rate, depth of cut and nose radius of the cutting tool. the proposed a...

This paper outlines the fractional factorial approach of D.O.E. techniques (Taguchi & Response Surface Methodology) are applied to optimize turning process parameter in order to obtain better surface finish. The turning parameters evaluated are cutting speed, feed, and depth of cut. An orthogonal array, signal-to-noise (S/N) ratio, and Pareto analysis of variance (ANOVA) are employed to analyze...

the machine to be designed and developed with a view to resolve one ofthe irksome problems of this institute has been facing every year. this institute issurrounded by vast non- fertile land area of about 200 acres, which becomes widelyoccupied by numerous breads of bushes and shrubs during post-rainy season. due tothis unwanted proliferation of such verdant institute gets abysmal look and that...

Laser cutting is widely used thermal energy based non-contact type, nonconvectional machining process. In the present research, the effect of laser machine processing parameters such as laser power, gas pressure, cutting speed and thickness effect on measured response such as surface roughness. The experiment was designed according to Taguchi L27 orthogonal array with three different level of e...
