MATERIAL REMOVAL AND DIMENSIONAL INTEGRITY OF GREEN MACHINED W-NI-FE

摘要

In this research, the mechanism of material removal in green machining of unsintered tungsten alloy (W-Ni-Fe) was explored via orthogonal cutting. Parameters related to tool design (e.g. forces, stresses, and energy required during material removal processes at different settings) were calculated and compared. Dimensional integrity of production machining in pre-sintered tungsten alloy was also investigated via drilling and end-milling. The results, then, were compared with the conditions after sintering. Statistical analyses were used to quantify and explain the relationships among potential parameters. This research utilizes designed experiments and data analyses to investigate the material removal mechanism in green machining and the dimensional integrity of production machining pre-sintered tungsten alloy versus its status after sintering.
