Manufacturing Processes and Their Classifications in Everyday Life

The video tutorial explains the manufacturing process, which involves producing goods in large quantities using machines. It classifies manufacturing into four main processes: casting, forming, welding, and material removal. Each process is discussed in detail with examples. Casting involves pouring molten metal into molds, forming changes the shape of preheated metals, welding joins metal pieces using heat, and material removal eliminates unwanted material from workpieces.

What is the primary characteristic of a manufacturing process?

• Production of goods in small quantities

• Use of manual labor

• Production of goods in large quantities using machines

• Production of goods without raw materials

Which of the following is NOT a type of casting process?

• Sand casting

• Drop forging

• Investment casting

• Die casting

What is a common example of a casting process?

• Broaching

• Resistance welding

• Sand casting

• Wire drawing

In the forming process, what is typically done to the metal before shaping?

• It is cooled

• It is preheated

• It is painted

• It is polished

Which of the following is an example of a forming process?

• Drop forging

What is the main purpose of the welding process?

• To remove unwanted material

• To change the shape of metal

• To pour molten metal into a mold

• To join two metallic work pieces

Which gas is typically used in gas welding?

• Nitrogen

• Oxygen

• Carbon dioxide

• An inflammable gas

What is the primary goal of the material removal process?

• To change the shape of metal

• To join two pieces of metal

• To heat metal

• To remove unwanted material

Which of the following is NOT a material removal process?
