Experimental investigations on selection of optimal parameters in work roll grinding

Abstract

Todays manufacturing environment is driven by competition which existed never before Customers are demanding total solution to their needs and they want products of best quality at low prices In turn organizations are starting to improve the quality of their products Quality and productivity improvement are more effective when they are integral part of the product and process development cycle Throughout the world companies are developing quality management systems like ISO 9001 2000 and invest money to improve the quality of their products One of the critical requirements for the ISO 9001 2000 is to have adequate control over the process parameters and use of optimal conditions in machining operations During rolling operation work rolls lose their initial shape and surface conditions Work rolls used in hot rolling or cold rolling of steel show less wear but the roll surfaces lose their roughness and this influences the finished product as well Work rolls periodically grind to the required surface finish while leaving the surface free of feed chatter marks and surface irregularities Because of the increasing quality standards special attention must be paid to the design of roll grinding processes Besides the quality of the work rolls the grinding process must be sufficient for economical requirements
