Wear characteristics of the pointed diamond tool in ultraprecision and micro cutting of Al 6061 V-grooves

. In this paper three uniformly arraying patterns (GD, CC and UR) and one non-uniformly arraying pattern (NUR) of diamond grits are used to fabricate the mono-layer brazed diamond grinding tools. The wear characteristics of those grinding tools are compared. It is found that NUR tool wears faster than other uniformly arrayed tools in the wet grinding. The protrusion of diamond grits on NUR tool is much lower than that on GD, CC and UR tool after 20 h of wet grinding. By tracking one diamond grit’ wear processes on CC and NUR tools in the dry grinding respectively, it is found that the diamond grit on NUR tool is worn with the form of macro-fracture firstly, then is polished with large flattened area. However, the wear of diamond grit on CC tool keeps in a form of micro-fracture and a slow wear rate.

Tool wear measurement has drawn a significant of attention in the past decades. However, no research has been found on the investigation of tool wear measurement in ultra-precision raster milling (UPRM) process since it is a relative complex cutting process. In the present study, tool wear characteristics were identified by using cutting chip morphologies and a groove cutting. Tool wear investigation using cutting chips is effective because diamond tool wear characteristics can be directly imprinted on the cutting chip surface. Through the inspection of chip surfaces, the profile and location of the tool fracture can be identified. Also, through the groove cutting, the cutting edge retreat due to the tool flank wear can be identified. In this research, a mathematical model was established to calculate the tool retreat. The experimental result shows that the proposed tool wear investigation method is an effective method.

Monocrystalline Diamond

Face cutting of tungsten carbide was conducted using two monocrystalline diamond tools and three polycrystalline diamond tools to investigate the wear characteristics in terms of the crystal structure and composition of the diamond. It was found that the wear of the monocrystalline diamond tool depends on the crystal planes that form the rake face and flank face of the cutting tool, and a cleavage fracture occurs when the cutting force acts as a shear force on the (111) crystal plane. The binderless nano-polycrystalline diamond tool exhibits excellent wear resistance beyond those of the sintered polycrystalline diamond tool and chemical vapour deposition polycrystalline diamond tool, as well as better wear resistance than the monocrystalline diamond tool.

Mold Life

The use of hard and brittle materials for manufacturing optical parts, such as dies and molds are required in order to extend mold life. Although, cobalt-free tungsten carbide is one of the hardest materials, micro-cutting is very difficult due to its hardness and its brittleness. This paper investigates face turning of cobalt-free tungsten carbide using a nanopolycrystalline diamond [NPD] tool and Zinc dialkyldithiophosphate (ZnDTP) fluid. Surface roughness of the cobalt-free tungsten carbide achieved was 22nmRz, which is far larger than the theoretical value. That is, traditional cutting theory does not directly apply for face turning of cobalt-free tungsten carbide using NPD tool and ZnDTP fluid.
