Evaluation of control parameters’ effects on system performance with Taguchi method in waste heat recovery application using mechanical heat pump

“…As a result, Taguchi L 27 orthogonal array was preferred, which provides 26 degree of freedom for process parameter combinations. The voltage, rotation and electrolyte concentration are taken as input machining conditions from, which the material removal rate is examined [13]. The material removal rate is defined as the rate of surface material eradicated from the base material, which shows the machining efficiency.…”

INTRODUCTIONIn manufacturing industries the high-quality products are obtained by using conventional and non-conventional manufacturing processes, which make changes in size, shape, dimensions and surface quality of the product. Various non-conventional manufacturing methods are applied to machine the brittle and hard materials like glass, ceramics and composites materials [1]. The glass is one of the highest brittle and hard materials, hence it is a challenging task to machine it with conventional and non-conventional manufacturing processes. There are main three categories of glass material i.e. sodalime glass, phosphate glass and borosilicate glass. It is widely used in different fields due to its wide range of excellent properties such as corrosion resistance, high chemical resistance, optical transparency, biocompatibility, attractive appearance, superior optical, high specific strength, heat-resisting capacity, excellent mechanical hardness, excellent anodic bonding, high electrical resistivity, temperature stability, non-porosity, various reflective indices, homogeneity, durability, hydrophilicity and good surface quality. The applications of glass material is production of mirrors, photo-masks, data storage disks, microscopic slides, miniaturization of microfluidic devices for chemical and biological micro total analysis systems, touch screens, mechanical inertial sensors, oxide fuel cells and micro-pumps filters, printed circuit substrates, photographic plates, wafers, chemical apparatus, micro gas turbines, micro-electromechanical systems, mass spectrometry, microcapillary, electrophoresis and optomechatronic systems, optical telecommunication, optical The electrochemical discharge machining is integrated by electro-discharge and electro-chemical manufacturing technology. The sodalime glass is widely used in various fields such as biomedical, optical and industrial industries. Hence, in present study the electrochemical discharge drilling process is applied on soda-lime glass material to find out the material removal rate. The Taguchi method L27 orthogonal array is used for present investigation. The input process parameters are taken as voltage, rotation and electrolyte concentration whereas output response is considered as material removal rate. From this analysis, it is found that voltage is the most dominant parameter for material removal rate followed by electrolyte concentration and rotation for soda-lime glass.

“…If the F variance ratio ranks higher than the F standard value, the corresponding factor will have significant contributions to the overall results. The tables for various significance levels and different degrees of freedom are available in most handbooks [26]. Tab.3 and Tab.4 show the range and variance analysis for the calculation of joint acceleration response, where the T i is the summation results of the data at same level, T is the sum of all 27 results of the experiment, i x is the mean value of the same level results, R j is the maximum difference value of i x , SS is the sum of the squares, df the degree of freedom, MS the average sum of squares and F is the significance indicator.…”
