Grinding Process Validation Approach (gPVA)

grinding operations are usually set up experimentally by testing different FP sets on actual workpieces, which render the whole optimization process risky, cost intensive and ineffective. This paper presents a load-controlled approach, hereinafter referred to as the gPVA (grinding Process Validation Approach), both to determine the process

Grinding Machining Process : Complete Notes -

In the grinding process, a layer of abrasive is responsible for removing the material from the work piece. As machining starts, the abrasives of grinding wheel and work piece comes into contact and due to the rubbing force the initial layer from the grinding wheel is worn out and a fresh layer of the abrasives involve in machining this process is continuously repeated until complete machining is done.
