Sheet metal forming involves processes such as bending, stamping, and stretching to shape thin metal sheets into parts. It is used in industries like automotive, aerospace, and electronics to create components like panels and casings.
What does extrusion primarily produce?
A Continuous shapes
B Thin films
C Solid rods
D Hollow parts
Extrusion involves forcing material through a die to create long, continuous shapes like pipes, rods, and profiles. It is often used with materials such as metals, plastics, and rubber to produce uniform, high‐quality parts.
What is the main purpose of drilling in manufacturing?
A Shaping
B Cutting
C Polishing
D Boring holes
Drilling is a machining process used to create round holes in a workpiece. A rotating drill bit removes material, creating holes of various diameters and depths, often used in automotive, aerospace, and construction.
Which process uses a rotating tool to cut material?
A Grinding
B Turning
C Milling
D Stamping
Milling uses a rotating cutting tool to remove material from a stationary workpiece. It is used for shaping parts, creating slots, and machining complex surfaces, and it can handle materials like metals, plastics, and wood.
What is the purpose of a die in sheet metal forming?
A Drilling
B Shaping
C Cutting
D Grinding
In sheet metal forming, a die is used to shape or cut the metal into desired forms. The metal is placed between two dies, and pressure is applied to form shapes such as brackets or panels.
What material is commonly used in extrusion?
A Plastic
B Metal
C Glass
D Wood
Plastic extrusion is one of the most common uses of the extrusion process. In this process, plastic is heated and forced through a die to create long shapes like pipes, sheets, or profiles used in various applications.
What is the main advantage of sheet metal forming over other methods?
A Speed
B Precision
C Cost-effectiveness
D Flexibility
Sheet metal forming is highly cost effective for producing large quantities of parts. The processes are simple, fast, and efficient, making it ideal for industries that require mass production of parts with consistent quality.
What does the extrusion process involve?
A Molding
B Cutting
C Joining
D Shaping by pressure
Extrusion involves pushing material, often plastic or metal, through a die to form continuous shapes with consistent cross sections. This process is widely used for manufacturing pipes, rods, and profiles.
What is the primary purpose of using jigs in manufacturing?
A Shaping material
B Holding workpieces
C Cutting material
D Polishing
Jigs are used to hold and position workpieces during machining operations. They ensure that the workpiece is accurately aligned and held securely, allowing for consistent and repeatable results in manufacturing processes.
What is the main characteristic of the drilling process?
A Material removal
B Cutting
C Shaping
D Joining
Drilling is a process where a rotating tool removes material to create holes in a workpiece. It is one of the most common processes used for producing round holes with specific diameters and depths.
What is the function of stamping in manufacturing?
A Drilling
B Cutting
C Shaping
D Cooling
Stamping is used in sheet metal forming to shape, cut, or emboss material by applying pressure with a die. It is commonly used to produce components like automotive body panels, electrical parts, and appliances.
What does extrusion help create in manufacturing?
A Cylindrical parts
B Continuous parts
C Small parts
D Large parts
Extrusion is used to create continuous parts with a consistent cross section. These parts are produced by forcing material through a mold, and the process is commonly used to create items like pipes, rods, and window frames.
What is the main function of a lathe in manufacturing?
A Turning
B Shaping
C Cutting
D Drilling
A lathe machine rotates a workpiece while a cutting tool shapes it. It is primarily used for turning operations, such as creating cylindrical parts, and can also be used for tasks like drilling and facing.
Which of these is used to apply heat for shaping materials in the molding process?
A Press
B Die
C Hammer
D Furnace
Molding often requires applying heat to materials like plastic or metal to make them soft and pliable before they are pressed into molds. A furnace is used to heat these materials to the necessary temperature.
What is the main advantage of using extrusion for plastic products?
A High strength
B Cost-effectiveness
C Consistent shapes
D Speed
Extrusion provides a consistent, uniform cross section along the length of the product. This makes it ideal for producing long plastic parts such as pipes, tubes, and profiles with exact dimensions and minimal material waste.
