151 Design and Structural Analysis of 3 Axis CNC Milling ...

2019-10-11  Cast iron is mainly an alloy of iron, carbon, and silicon. From primary times cast iron has been the most commonly used material for machine tool structures. It may be cast into complex and complex shapes. It is easily machined and may be hand scraped and lapped to a high degree of accuracy. It has fairly good damping properties and also has reasonably good antifriction properties helped by the graphite contained in it. It can be given very good long-term dimensional stability by giving it a special long cycle stress relief annealing treatment. Cast iron should be preferred for complex structures subjected to normal loading, when these structures
