Machining Dynamics in Grinding Processes

Grinding has traditionally been a finishing operation, as it is today for many precision parts. With the advance of technology, grinding has extended its application to a roughing process. Today the grinding process has been successfully applied to almost all types of material removing processes with an extremely high material removal rate of more than 3,000 mm3/(mm s) and ultraprecision accuracy to the nanometre lever surface finish. Due to the high hardness of abrasives used as cutting media, grinding is often the first choice for removing materials of a high hardness. Grinding is becoming one of the most popular choices of machining processes, which comprises 25% of total machining processes [1]. A recent survey [2] shows that the application of grinding is still increasing and is becoming the most popular material removal process in industry. The wide use of the grinding process is becoming an important feature of manufacturing process in modern industry.
