Milling Flashcards
Week 4
What are 3 styles of mills?
(1) Horizontal
(2) Vertical
(3) Ram style (Bridgeport)
What is the difference between conventical milling and climb milling?
In Conventional milling, the work moves opposite the direction of the cutter. In Climb milling, the work moves the same direction as the cutter.
What can happen to your tooling if climb milling without anti-backlash?
Your tool can brake or snap
True or False:
End mills with 2 flutes can be used for plunging and milling.
True
Two flute end mills aka slot drills
Can 4 flute end mills be used for plunging?
No! 4 flute end mills cannot be used to plunge
What can be used in place of a vise when on a mill?
Work can be held down with milling table clamps with T-slot bolts.
What simple tool can you use when setting the cutter on a mill?
Paper!
Paper about .002” - .003” with machine in neutral (between Low and High)
True or Flase:
When milling odd shapes, you can use aluminum round bar in the vise to assist with work holding.
True
When aligning a vise on a mill, what tool can get you to rough accuracy vs a precise accuracy?
Machinists square - good to .015” to .030”
Dial indicator - good to <.001”
What are some different types of tooling for the mill?
Face Mill (HHS and Carbide teeth)
Dovetail
T Slot
Woodruff Key
How should you set multiple teeth on a fly cutter?
Use a dial indicator to ensure all teeth are set to the same height for consistent cutting.
(Fly cutters are used for surface finishing, facing operations, and machining large areas - lighter workloads than a face mill. Can be used for engraveing and etching.)
Why should welds be kept away from milling machines?
Welds have harder, inconsistent deposited material that can damage tools and affect machining accuracy.
Per James’ slides - yes lots of us put our welded vises on the mill
