REDUCTION IN PROCESS TIME OF SHOT PEENING METHOD BY VARYING PROJECTION ANGLE AND PULLEY DIAMETERS

The aim of this research is to study the effect of changing various parameters of the shot peening process on the productivity of the manufacturing of coiled springs. The manufacturing process of Coiled spring involves various processes including shot pee ning . This process strengthens the steel to resist metal fatigue and cracking during its lifetime of repeated flexing. Within this research a modification in the finishing operation of shot peening process is presented. The variation of the Peening time with the variations of projection angle and Pulley Diameters is observed. The results have been verified and presented. It has been found that with the adjustment of the proper projection angles and pulley diameters for the shot blasting process the manuf acturing time can be reduced by 5 to 6 minutes.
