Analysis of Temperature Distribution in Grinding of Composites Using Finite Element Method
ثبت نشده
چکیده
In this investigation, experiments were carried out to understand the influence of various grinding parameters like wheel speed, workspeed and depth of cut on the grinding temperature at the surface of the Al-SiCP composite workpiece with different grinding wheels. The temperature distribution within the workpiece was studied by simulating the grinding process and using finite element analysis package with transient thermal analysis. Specific energy as the input, the temperature distribution for dry grinding condition and with coolant were analysed. The wheel loading was quantified by conventional methods. The temperature at the surface is much lower for composite materials than steel. The influence of various grinding parameters on the surface temperature are marginal. Eventhough partition ratio is lower for diamond, but the temperature developed at the surface is more for diamond compared with other wheels. The affinity to wheel loading is more for diamond wheels than other wheels. The CBN shows better results than other wheels. The influence of coolant is significant.
