Optimization of process parameters is the key step in response surface methods to achieve high quality without cost inflation. The multi-response optimization of the machining parameters viz, chip-tool interface temperature, main cutting force and feed force on lathe turning of En-31 steel as alloy steel using RSM with grey relational analysis is reported. A grey relational grade obtained from ...

In above rated conditions, wind turbines are often subjected to undesirable high structural loading. We investigate two feedback control techniques in combination with a feedforward control method for reducing blade flap bending loads in above rated wind conditions. The feedback controls studied include both disturbance accommodating/tracking and integral augmented/repetitive types that incorpo...

This experiment was conducted to assess the effect of chicken genotype on the growth performance, feed intake and feed conversion efficiency of the progenies resulting from purebred (Giriraja (Gr) X Giriraja (Gr)), straight (Gr male X Alpha female), reciprocal (Alpha male X Gr female) and Alpha male X White Leghorn (WL) female crosses. Data obtained on body weight, body length, breast girth, ke...

vibration cutting (vc), elliptical vibration cutting (evc) and ordinary cutting (oc) of in738 work-pieces have been experimentally investigated in the present research. the experiments were carried out by using single crystal diamond tool and ultra-precision cnc lathe. vibration frequency is 36.16khz and the amplitude is . the influence of various cutting parameters including cutting speed, fee...

Machining of hard materials is a recent technology for direct production of work-pieces. The primary challenge in machining these materials is selection of cutting tool inserts which facilitates an extended tool life and high-precision machining of the component. These materials are widely for making precision parts for the aerospace industry. Nickel-based alloys are typically used in extreme e...

The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility inde...
