Abstract: Grinding is a process of material removal in the form of chips by the mechanical action of regularly shaped abrasive particles bonded together in a grinding wheel. Grinding wheel is a multipoint cutting tool composed of selectively sized abrasive grains held together by a bonding material. Grinding as a system comprises of various components namely grinding wheel, grinding machine, dresser, coolant and a workpiece. newline newlineWith such variables in the design of the grinding system, the best combination can be achieved if the optimisation process is used. Optimisation of grinding system can be done for so many parameters like life of the wheel, cycle time reduction of the grinding process, cost of grinding etc. newline newlineThe overall objective is to improve the user s capability in understanding and designing the grinding system for optimal results. This has been approached by considering the various components of grinding as a system and attempting simultaneous optimisation. newline newline The result of such an integrated approach has been the following: newlineA method has been developed for the user to understand the equivalent wheel of newlinedifferent suppliers. A simple method for assessing the safety as well as characterising grinding wheels using sound level measurement has been developed. newline newlineA simple method for modifying the grinding machine, particularly with reference to improving the coolant flow has been demonstrated by a modified workrest blade. newline newlineMethods by which the performance of coolants can be enhanced by simple additives have been discussed. Two new methods for estimation of grinding temperature by the user have been developed. newline newlineThe effect of dressing has been analysed by a factor called Dulling factor. It is shown that this factor has a good correlation to the performance capability of the wheel and also to the form holding characteristic of the wheel. newline newlineUsing this Dulling factor and Taguchi method, a simple method has been developed to assess the best possible conditions to re-design the grinding system when wheels of different sources.
