According to the application of drawing process, the drawing are classified as
Deformation Processes
Subject and UNIT: Manufacturing Processes: Unit III: Bulk Deformation Processes
The process which is used to reduce the cross section of metal is called drawing.

There are two types of defects which can occur in rolled products. 1. Surface defects 2. Internal structural defects.
Working Principle, Types
Subject and UNIT: Manufacturing Processes: Unit III: Bulk Deformation Processes
In shape rolling process, the various shapes can be produced by deforming the work into a contoured cross section.
Subject and UNIT: Manufacturing Processes: Unit III: Bulk Deformation Processes
In rolling plates and sheet with high width-to-thickness ratios, the width of the material remains essentially constant during rolling process.

Rolling mill consists of rolls, bearings to support the rolls, gear box, motor, speed control devices, hydraulic systems etc.
Types of Rolling with Advantages, Disadvantage
Subject and UNIT: Manufacturing Processes: Unit III: Bulk Deformation Processes
The process of plastically deforming the metal into semi-finished or finished condition by passing it between two rollers is called rolling process.

Components produced by the forging process are much stronger.

The different types of defects that may occur during the forging operations are as follows:

Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state

This process is also called hot heading. In this operation, the metal is heated at one end and it is rest on the anvil and heavy blow is applied on the other end by using a hammer.

Forging of parts by presses involve slow squeezing of plastic metal in closed impression dies instead of applying repeated severe blows by hammers.
