Manufacturing processes.( SEMESTER + GATE )
1. Manufacturing process:- It is a process of converting raw material into a finished product by various processes , machines and energy. it is a processes of value addition to the raw material. * Classification: (i) Casting processes (II) forming processes (iii) fabrication processes (iv) material removal processes a. zero processes b. additive processes c. subtracting processes (i) Casting Processes:- In casting metals or alloy are initially heated to melt them .the molten metal is then poured into a mold cavity . where it is allowed to solidify. after solidification the product is taken out of the mold cavity and subjected to finishing operation as per requirement. *Advantages:- i. complex shape of the object can be produced. ii. it is simple and less expensive process. iii. Ductile and brittle material can be produced. iv. Large size object can be produced by cast...
