METAL FORMING

*Metals may be formed into useful shapes in two basic ways:

1. By plastic deformation processes in which the volume and

mass of metal are conserved and the metal is displaced from

one location to another.

2. By metal removal or machining processes in which material is

removed in order to give it the required shape.

*Metal forming processes may be classified into only a few

categories on the basis of the type of forces applied to the

work-piece as it is formed into shape.

� Direct-compression-type processes

� Indirect-compression processes

� Tension type processes� Tension type processes

� Bending processes

� Shearing processes

Thread-rolling for bolts:

Rolled threads stronger than machined (and less expensive)

Introduction

� Addition to producing various external or internal round profiles,cutting operations can produce many other parts with more complex shapes
