Wasting processes

Question 1

Describe the milling process

Answer 1

cuts slots, shapes edges or threads holes
work is camped on to table
table runs in x direction (horizontally L&R), y direction (horizontally forwards and backwards) and z (vertically)

Question 2

Describe turning

Answer 2

carried on centre lathe
work held in roasting chuck and machined to reduce diameter and square off end, thread and drill
manual or CNC

Question 3

Describe flame-cutting

Answer 3

used to cut low carbon and alloy steel plate
uses oxygen-acetlene gas and special flame cutting torch for intense flame
difficult to maintain parallel line

Question 4

Describe plasma cutting

Answer 4

fast and clean cut
uses conductive plasma gas to transfer energy from power supply to a conductive material which burns through the materials and blows it away

Question 5

Describe laser cutting

Answer 5

metal, manufactured boards, acrylic
power from high powered laser beam that is directed through optics
more accurate and uses less energy than plasma cutting but cannot cut to the same thickness of material

Question 6

Describe punching/stamping

Answer 6

computer controlled machines stamp out sections of sheet material
uses shearing action on sheet of metal plated between upper tool (punch) and lower tool
