Ultimately ductile grinding comes down to a consideration of material removal at translational micro or nano scale contacts the domain of indentation mechanics [26] The term ductile is not necessarily to exclude all microcracking in chip formation but rather to ensure that any such cracking does not extend into the machined subsurface
The grinding process is one of the most important and widely used machining processes to achieve the desired surface quality and dimensional accuracy Due to the stochastic nature of the grinding process and process conditions the instantaneous micro mechanisms between each grain and the workpiece are momentarily changing and are different from the
