Process, Techniques + Specialist Tools

Question 1

What is metal turning?

Answer 1

Metal turning is a material removal process used to create rotational parts by cutting unwanted material. Metal turning process a machining process where a lathe is used to rotate the metal while a cutting tool moves in a linear motion to remove metal along the diameter, creating a cylindrical shape.

Question 2

Advantages of metal turning

Answer 2

• cost effective
• greater flexibility
• design quicker.

Question 3

Disadvantages of metal turning

Answer 3

• only rotatable components are permitted
• expensive equipment
• creates a substantial amount of scrap material.

Question 4

What is Stamping/punching?

Answer 4

Stamping andpunchingarecommon metal-working processes employed in the creation and shaping of metal sheets.

Question 5

Advantages of stamping/punching

Answer 5

• cost effective
• high speed
• precision
• reduces the use of multiple machines, the number of workers, as well as labour time which as a result significantly reduces production costs.

Question 6

Disadvantages of stamping/punching

Answer 6

• time consuming
• limited to standard size and shapes and tools are expensive.

Question 7

What is metal pressing?

Answer 7

Metal pressing is involves placing flat sheet metal, in either coil or blank form, into a stamping press.

Question 8

Advantages of metal pressing

Answer 8

produces highly precise shapes through stamping, resulting in a uniform design throughout

Question 9

Disadvantages of metal pressing

Answer 9

• time consuming, someone has to be on the machine
• can be expensive.
  Examples: brackets, hinges.

Question 10

What is a CONVENTIONAL METAL CUTTING LATHE?

Answer 10

Is suitable for turning internal and external cylindrical, conical and swing surfaces as well as various metric, inch, module and diametric pitch threads.
The conventional metal cutting lathe is a machine that rotates a cylindrical object against a tool that the individual controls. The general operation is turning, facing, threading and grooving.

Question 11

Advantages of CONVENTIONAL METAL CUTTING LATHE

Answer 11

• versatility
• precision and ability to perform a wide range of operations such as turning
• facing
• threading
• drilling

Question 12

Disadvantages of CONVENTIONAL METAL CUTTING LATHE

Answer 12

• risk of injury if not used properly
• high initial cost
• need for regular maintenance.

Question 13

What is a CNC METAL CUTTING LATHE?

Answer 13

A CNC metal lathe is a machine designed to rotate a metal workpiece on a central spindle. This allows an accurate cutting tool to be used on the inside or outside of the workpiece

The primary CNC lathe machine operations are: Cutting involves separating large amounts of material from a workpiece with a sharp-edged cutting tool. Deformation involves physically changing the shape of a workpiece by removing material from it.

Question 14

Advantages of CNC METAL CUTTING LATHE?

Answer 14

• produce little to no waste
• fast and efficient
• no need for highly skilled people.

Question 15

Disadvantages of CNC METAL CUTTING LATHE?

Answer 15

• highly expensive
• can break down and lead to high costs and need lots of maintenance and repairs.
