Machining, Chipping, Grinding, and Rolling in Engineering

Final answer: Machining, chipping, grinding, and rolling are engineering processes used to shape, finish, and modify materials.

Explanation: Machining, chipping, grinding, and rolling are all processes used in engineering to shape, finish, and modify materials. Each process has a specific purpose and application:

• Machining: This process involves the removal of material from a workpiece to create the desired shape or size. It can be done using various tools, such as lathes, milling machines, or drills.
• Chipping: Chipping is the process of removing small pieces of material from the surface of a workpiece using a chisel or similar tool. It is commonly used to clean the edge preparation on a plate before welding.
• Grinding: Grinding is the process of using an abrasive wheel or belt to remove material from a workpiece. It is often used to achieve a smooth or polished surface finish.
• Rolling: Rolling is a forming process that involves passing a workpiece through a set of rollers to apply pressure and shape the material. It is commonly used in metalworking to produce cylindrical or sheet metal parts.
