Non Traditional Machining Processes: Insights and Applications from P.K. Mishra's Book
although great progress has been made in the understanding of the wear and friction characteristics of tools and processing conditions, there are several key points that are still unaddressed. first, not enough work has been done to study the effects of rotational speed of the tool on the microstructure and properties. second, it is unknown how the tool and processing conditions affect the wear of the tool. and third, the effects of tool damage on the microstructure and properties is not known. furthermore, key questions are whether the tool wear and tool damage effects can be measured and quantified, and what is the correct strategy for tool wear and damage management? in addition, there is still very little knowledge on how the tool and process conditions effect the surface roughness. it is also unclear how the surface finish and surface roughness influences the wear and friction behavior of the tool. it is also unclear how tool wear and tool damage effects the tool/process interactions, tool/substrate interactions, and the surface chemistry of the tool and substrate interface. these questions are critical to developing a machining process that can be integrated into the current industrial manufacturing flows.

at least three challenges of the additive manufacturing (am) process have been highlighted in this paper: surface finish, tool wear, and tool damage. in this paper, the author reported that the roughness of the surface finishes produced by the am process is less than that of traditional machining processes. this is due to the fact that the am process has to be operated with ultrahigh build rates to avoid the heat induced tool wear and damage. the combination of the ultrahigh build rates with the non-traditional machining processes produces an am process with better surface finish than that produced by the traditional machining process. due to the ultrahigh build rates, the tool wear and damage become more significant than the traditional machining process. in fact, the tool wear and damage is so significant that the am process can only be operated for a short period of time.
