Magnetorheological finishing of grooved drum surface and its performance analysis in winding process

Abstract

The fine level finishing of grooved drum surfaces is an essential requirement for enhancing the performance of the winding machines in today’s textile industries. The fine level of finishing is required as less as possible on the grooved surface of the textile winding drum. With the least possible roughness value over the external grooved surface of the winding drum, the breakage of the yarn and hairiness of the yarn gets reduced. To accomplish the requirement of finishing the grooved surface of the winding drum, a rectangular-rotating magnetorheological (MR) finishing process is utilized. After the MR finishing, the functional performance of the already using ground grooved winding drum in industry and the present MR finished grooved winding drum has been compared and examined their performance. The functional performance of the MR finished grooved drum is found better than the ground grooved winding drum due to the fine level of finishing. After 60 min of MR finishing, the average surface roughness value of the grooved drum surface gets reduced from 200 nm to 10 nm. Scanning electron microscopy and mirror images are also conducted. These results showed better surface characteristics with the MR finished grooved winding drum than the ground grooved winding drum. After the MR finishing operation, the grooved winding drum is taken to the textile industry. In the industry, the effect of surface roughness on the functional life of the grooved drum is investigated in the winding process. The functional performance has been found better with the MR finished grooved drum surface in the winding process than the ground grooved drum surface.
