GREY CAST IRON
|Abstract:||No data is available for the role played by miech metal on the microstructure, machinability i d mechanical properties of grey cast iron. Though a little qualitative study of the effect of chromium has been made in the past , systematic quantitative data is lacking in the literature an no justifiable conclusion can be drawn out of them. The present investigation has been undertaken with a view to explore the possibility of miseh metal as beneficial alloy addition on the machinability and mechani-cal properties, since India has plenty of its deposLts; and also to find out the quantitative data in chromium alloyed cast irons. The study has been carried out under varying r conditions of cutting speeds, feeds and depths of cut and an attempt has been made to bring a correlation between the various factors to provide the machinists the most optimum practical data for shop use. Machinability has been evaluated in terms of tool life and chip formation. A lathe tool dynamometer has also been developed to measure the cutting forces for evaluating machinability of cast irons treated with much metal.|
