grinding machine, when holds hammers, pulley and fan. The failures of shaft bearing were observed due to non uniform distribution of stress. The study was under taken to conduct simulation study of shaft for stress analysis with the help of FE software ANSYS 12.0.1. Keywords Biomass Grinder, FEM,
chuck rotation, grinding wheel rotation, and cooling fluid pump). The grinders main power switch was at a junction box at the rear of the machine. The grinder was enclosed on three sides and open at the front. A removable machine guard was placed on the front of the machine before it was operated. The incident occurred Thursday, May 30, 1996.
grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel.
Shaft is an essential component of grinding machine, when holds hammers, pulley and fan. The failures of shaft bearing were observed due to non uniform distribution of stress. The study was under taken to conduct simulation study of shaft for stress analysis with the help of FE software ANSYS 12.0.1.
with much of the analysis presented here focused on milling metals. Other machining activities, such as grinding, along with newer non-traditional forms of machining, such as electrical discharge machining and waterjet machining, are excluded from this analysis. BACKGROUND While a

costs are additional benefits of Electrical Safety programs. When electrical faults occur, the electrical system is subjected to both thermal and magnetic forces. These forces can severely damage equipment and are accompanied by fires, explosions and severe arcing. Such violent damage often causes death or
