Proper understanding of chip morphology and surface quality is important for the optimization of machining procedures with regard to improvement in general effectiveness while turning AISI 304 stainless steel. Moreover, the use of sunflower oil coolant in this research work is expected to provide an insight into its functionality in lessening heat generation, hence offering room for improvement in chip evacuation for a better surface finish. In this work, turning of AISI 304 stainless steel was performed using sunflower oil as a coolant in order to study chip morphology under dry and wet conditions. The main objective of this work is to assess the influence of cooling methods and cutting conditions on chip formation and surface quality. Chip morphology and surface roughness presented distinct features between coolant-assisted and dry machining. When the chips were dry, it was noticed that they would be longer and more continuous, which would probably build up edges. The surface roughness during dry machining was greater compared to coolant-assisted machining. These results prove that the surface quality of AISI 304 stainless steel turned using sunflower oil as a coolant may be considerably improved. In general, the improvement of cooling techniques and cutting conditions will lead to a great increase in machining efficiency and quality of AISI 304 stainless steel.

摘要

Proper understanding of chip morphology and surface quality is important for the optimization of machining procedures with regard to improvement in general effectiveness while turning AISI 304 stainless steel. Moreover, the use of sunflower oil coolant in this research work is expected to provide an insight into its functionality in lessening heat generation, hence offering room for improvement in chip evacuation for a better surface finish. In this work, turning of AISI 304 stainless steel was performed using sunflower oil as a coolant in order to study chip morphology under dry and wet conditions. The main objective of this work is to assess the influence of cooling methods and cutting conditions on chip formation and surface quality. Chip morphology and surface roughness presented distinct features between coolant-assisted and dry machining. When the chips were dry, it was noticed that they would be longer and more continuous, which would probably build up edges. The surface roughness during dry machining was greater compared to coolant-assisted machining. These results prove that the surface quality of AISI 304 stainless steel turned using sunflower oil as a coolant may be considerably improved. In general, the improvement of cooling techniques and cutting conditions will lead to a great increase in machining efficiency and quality of AISI 304 stainless steel.
