“…The density, hardness, flexural strength etc. were listed in, they were 2.18 g/cm 3 , 0.13 ± 0.1 GPa, and 2.3 ± 0.2 MPa respectively. On basis of the study, the minimum strength of green ceramics to satisfy cutting condition was 2.0 MPa.…”

“…The microstructure of the green body was quite homogeneous and there were few bubbles as shown in Figure a. Based on the enlarged SEM micrograph from Figure b, it could be concluded that there had no crystal boundary forming between Al 2 O 3 particles, the binding forces were just cohesive force generated by paraffin and mechanical entanglement . The density, hardness, flexural strength etc.…”

“…EDS of point A and B in Figure d confirmed that substances were the materials of green Al 2 O 3 ceramics. It was consist with literatures, the flank‐face textures possessed function of derivative‐cutting in terms of processing green Al 2 O 3 ceramics, exerting additional cutting to hard inclusion between the tool‐workpiece interface which served as the removal of hard inclusions, the additional cutting prevented hard inclusions from scratching unworn face of tools. It was advantageous for extending tool life.…”

“…So in combination with the literature, the diagrammatic drawing of the effect of the flank‐face textures (MT tool) in terms of processing green ceramic compacts was concluded in Figure . Derivative‐cutting worked on improving the surface quality when machining green Al 2 O 3 ceramics, which could remove visible hard inclusions on the surfaces of green ceramics.…”

Green Al2O3 ceramics through cold isostatic pressing were produced. Scratch tests were performed to evaluate the machinability. Texturing was applied on the flank‐face of the WC/Co tools by laser. Tools with textures on the flank‐face were adopted in dry cylindrical turning of the green Al2O3 ceramics. Characterization of green ceramic surfaces machined by flank‐face textured tools was studied. Results revealed that green ceramics had good enough machinability in cutting tests and scratch tests. There were no visible cracks on the surface after machining. Flank‐face textured tools could improve the surface integrity during processing green Al2O3 ceramics. Mechanisms responsible were found that derivative‐cutting behavior by flank‐face textures was able to remove visible hard inclusions on surfaces of green ceramics, which made the surfaces much smoother. More tiny ceramic powders generated by the phenomenon were pressed on the surfaces of green ceramics, which made further efforts on improving surface quality. Machining parameters had significant impacts on surface integrity. Within machining parameters, surface quality became better and compaction area was found on surfaces of green Al2O3 ceramics with the increase of cutting depth, but there were still visible hard inclusions and spalling of materials on the surface after machining.

This paper presents a novel grinding enabled texture, 'V' shaped texture (VST), on flank face. To implement the texture on a cutting performance, a set of chamfering experiments of stainless steel materials used as 3C product shell usually are presented. Cutting forces, surface qualities, and tool wear are measured and compared, of which results show that both smallest surface roughness and longest tool life are achieved by using a 30°VST chamfer tool. By comparing the results, a clear conclusion can be drawn that texture types and angles are not independent factors to cutting performance; therefore, a suitable combination of texture types and texture angles can provide a significant improvement of tool life and surface quality.
