Machinability Studies of Al/SiC/(20p) MMC by Using PCD Insert (1300 grade)

摘要

Aluminium Silicon Carbide (A356-Sic) Metal Matrix Composite (MMC) materials have a set of mechanical and physical properties that are ideally suited for application in Aerospace and Automobile industries and not widely used because of its poor machinability. To over come this barrier, our investigation is to study on machinability analysis of A356 -SiC(20p) (MMC) with Poly Crystalline Diamond (PCD) insert of grade 1300.Base matrix material is Aluminium A356 reinforced with 20% weight by volume of Silicon carbide particles of mean diameter 55 μm to 80 μm is used. The main focus of investigation is to determine minimum power consumed by main spindle, good surface finish and minimum tool wear. The worn out insert is also analyzed under Scanning Electron Microscope (SEM) and the results would be discussed.
