Introduction:
Normally, a product is only competitive to the counterparts from its competitors only if the product has been designed with better or equivalent functionality and appearance, and yet is cheaper than the similar products in a market. Proper selection of manufacturing processes in producing the product significantly reduces its manufacture cost, hence its competitiveness.
An engineering drawing shows the detail design of a component in a product. There are number of forming processes available to convert a bulk of material to the geometry of a component and to achieve its designed specifications so as to fulfill its anticipated functionality. Material removal processes are commonly used in shaping the bulk of material to the component by removing those unwanted parts and keeping those parts specified in a design drawing. Typical conventional material removal processes include: turning a component using lathe; drilling holes by a drill; shaping surfaces, slotting a groove/recess, drilling and boring blind
