Optimization of bone drilling using Taguchi methodology coupled with fuzzy based desirability function approach

Evaluation of delamination in drilling of bone

“…The experiments are conducted on bovine femoral diaphysis (middle part) as it is the closest animal bone having properties similar to the human bone and has been used widely in previous investigations by several researchers [4,5,[15][16][17][18][19][20]. The comparison of the properties between the human and bovine bone is listed in Table 1 [4,5,[15][16][17][18][19][20]. The bovine femur was obtained from a local slaughter house immediately after slaughtering and the diaphysis was obtained by removing the both proximal and distal ends using a hack saw.…”

“…The bovine femur was obtained from a local slaughter house immediately after slaughtering and the diaphysis was obtained by removing the both proximal and distal ends using a hack saw. The levels for each bone drilling process parameters were selected based on the wide range of experiments reported in the literature [4,5,[15][16][17][18][19]. L 25 experimental design of orthogonal arrays comprising of 25 experiments was selected for carrying out the experimental trial.…”

“…The experiments were carried out with HSS (High speed steel) drill bits to minimize the effect of wear [5]. The experiments were performed within few hours of the slaughter to retain the mechanical and thermo-physical properties of the bone [15][16][17][18][19]. No animal was sacrificed specifically for this research purpose.…”

Multi-objective optimization of PMEDM using response surface methodology coupled with fuzzy based desirability function approach

“…They found an optimal parametric combination of peak current =1A, pulse on time= 10µs, tool-work time=0.2s, tool lift time= 1.5s to reduce the surface integrity as well as the dimensional accuracy . Pandey and Panda (2015) adopted the Taguchi methodology in combination with fuzzylogic based on desirability function to optimize the bone drilling process to minimize the drilling induced damage bone. Bhaumik and Maity (2014) studied the effect of tungsten carbide electrode on the machining performance of EDM during machining of AISI 304 and optimizing the responses viz.…”

Optimization and practical verification of system configuration parameter design for a photovoltaic thermal system combined with a reflector

“…The study found the optimal parameters and the confirmatory tests result fall within the accepted confidence interval. Pandey et al (2013) used Taguchi method coupled with the fuzzy logic approach for the optimization of bone drilling process. The multiple responses were aggregated into a single multi-performance index using fuzzy based desirability function which was then optimized by using the Taguchi method.…”
