What is the main meaning of manufacturing?
The process of testing the quality of finished products
The process of converting raw materials or scrap into useful products by adding value
The process of packing and delivering products to customers
The process of storing raw materials in the warehouse
Which of the following is NOT a primary manufacturing process?
Casting
Forging
Welding
Machining
Which statement is TRUE about primary manufacturing processes?
They produce very fine surface finish
They achieve very close dimensional tolerance
They provide the basic shape and size to the product
They always produce attractive appearance
What is the main function of a lathe machine?
To drill internal holes only
To cut a workpiece by turning process
To grind flat surfaces only
To bend metal sheets
What is the main purpose of using cutting fluids in turning operations?
To increase the weight of the workpiece
To change the colour of the surface
To cool, lubricate, and improve tool life and surface finish
To stop the workpiece from rotating
Which force in turning acts downward on the tool tip?
Radial force
Thrust force
Cutting force
Friction force
What is milling?
A process of producing only cylindrical shapes using a single-point tool
A process of producing flat and complex shapes using a multi-tooth cutting tool
A process of drilling holes using a rotating drill bit
A process of cutting threads on a workpiece
In peripheral milling, how is the cutter positioned relative to the workpiece surface?
Perpendicular to the workpiece surface
At 45° to the workpiece surface
Parallel to the workpiece surface
At 60° to the workpiece surface
In face milling, the axis of the cutter rotation is:
Parallel to the workpiece surface
Perpendicular to the workpiece surface
Tangent to the workpiece surface
At a fixed 30° angle to the workpiece surface
Why is 3D printing called an additive manufacturing process?
It removes material from a solid block
It uses only liquid materials
It stacks and fuses layers of material to build a part
It requires a mold to form the product
Which of the following is a correct statement about 3D printing materials?
Only metals can be used in 3D printing
Plastics are widely used and can come in filament, resin, granule, or powder form
All 3D printing plastics are toxic and unsuitable for home use
3D printing materials must always be in liquid form
Which 3D printing material is made from biological sources such as cornstarch or sugarcane?
ABS
PLA
PVA
HDPE
What is the main advantage of using CNC machines in manufacturing?
They require no programming
They increase human involvement in every step
They provide higher efficiency, accuracy and consistency than manual processes
They can only make simple 2D parts
Which statement best describes G-code in CNC machining?
It controls the use of coolant and tool changes
It is used only to start and stop the machine
It is the geometric code that tells the machine how to move
It is only used for drilling operations
In CNC turning, how is material removed from the workpiece?
The tool rotates while the workpiece is stationary
The cutting tool moves randomly over the surface
A single-point cutting tool moves linearly along a rotating workpiece
The workpiece is heated until it melts away
What is casting in manufacturing?
A process of cutting metal blocks into smaller pieces
A process where liquefied material is poured into a mold and allowed to harden
A process of joining metals by welding
A process of machining solid metal into shape
Why is casting widely used in manufacturing?
It can only produce simple shapes
It is only suitable for plastic parts
It can produce complex solid and hollow shapes that are difficult to make by other processes
It does not require any mold
Investment casting is also known as:
Pressure casting
Lost wax casting
Sand mold casting
Permanent mold casting
