“…The low cost and high precision makes grinding important for the processing of PMMCs to obtain desired dimensional tolerances and surface integrity. * Ruisong Jiang jiangrs@nwpu.edu.cn 1 Up to the present, a lot of work has been carried out to understand the grindability and surface integrity of conventional materials by analyzing the process as an interaction system between the surface of the wheel and the workpiece [10][11][12][13][14]. However, there are only a few investigations on the grindability and surface integrity of PMMCs [6].…”

In situ TiB 2 particle-reinforced aluminum matrix composite (in situ TiB 2 /Al composites) is a new kind of metal matrix composite. With in situ synthesis method, a better adhesion at interfaces is achieved and hence improves mechanical properties. However, few literature focused on its grindability and surface integrity which limited its widespread use in industries. In this paper, the effects of grinding parameters and grinding wheels on the grinding performance of in situ TiB 2 /Al composites are investigated experimentally. The results show that the grinding performance is mostly affected by the wheel speed and grinding depth. The signal alumina wheel has the best grindability in grinding in situ TiB 2 /Al composites. Unlike other ex situ PMMCs, the in situ TiB 2 / Al composite is removed in a ductile-mode and pull-out or fractured particles are not found on the ground surface. Surface thermal softening effect and residual tensile stress indicate thermal effect dominate over mechanical effect in the grinding process. These results can be used to understand the material removal mechanism of grinding in situ TiB 2 /Al composites.

“…Materials which are often used in the aerospace industry are nickel based alloys, especially Inconel 718 alloy. The chemical composition of this alloy as well as physical and mechanical properties have negative influence on its machinability and grinding process [7]. Very often turning, milling or broaching Inconel alloys is too expensive and time-consuming, that's why these machining methods are usually replaced by grinding.…”

“…It is widely used in the design of MEMS devices [74] and the examination of bio-inspired functional surfaces [147], e.g., manufacturing of microfibrillars by soft lithography on a PDMS. In nanomachining, the tool wear [41] and machined surface [116] are often examined by SEM. A shortcoming of SEM is the inaccuracy in the geometric measurement, which can be overcome by AFM.…”
