What are the two main types of milling machines?
Horizontal Milling Machine and Vertical Milling Machine
What is the cutter axis orientation in horizontal milling?
Parallel to surface being machined
What is the cutter axis orientation in vertical milling?
Perpendicular to surface being milled
In horizontal milling, where are the cutting edges located?
On the outside periphery of the cutter
In vertical milling, where are the cutting edges located?
On both the end and outside periphery of the cutter
List the operations involved in horizontal milling.
- Slab milling
- Slot Milling
- Form milling
- Gang milling
- Straddle milling
- Slitting milling
- Gear milling
- Angular milling
List the operations involved in vertical milling.
- Face milling
- End milling
- Profile milling
- Pocket milling
- T slot milling
- Surface profile
What is the chip thickness characteristic of conventional milling?
Max chip thickness is at the end of the cut
What is an advantage of conventional milling?
- Tooth engagement is not affected by workpiece surface characteristics
- Cutting process is smooth
What is a disadvantage of conventional milling?
- Tendency for the tool to chatter
- Workpiece may be pulled upward
What is the chip thickness characteristic of climb milling?
Max chip thickness is at the start of the cut
What is an advantage of climb milling?
Downward compression of cutting forces holds workpiece in place
What is a disadvantage of climb milling?
- Requires a rigid setup due to high impact forces
- Not suitable for workpieces with surface scale
