10 Questions
In a plain milling machine, what movement is not possible in a horizontal plane?
Swivel
What distinguishes a universal milling machine from a plain milling machine?
Ability to perform angular and helical milling operations
What type of milling machine has the cutter spindle positioned vertically?
Universal vertical milling machine
What distinguishes a peripheral milling operation from a face milling operation?
In peripheral milling, the cutting edges are on the outside periphery of the cutter, while in face milling, they are on the end and outside periphery.
What is the main function of an arbor in milling operations?
To mount and key cutters that have a bore at the center in milling machines.
What is a defining feature of a universal milling machine compared to other types of milling machines?
It has a knee that can be adjusted up and down for vertical alignment of the spindle.
What is the formula to convert spindle rotation speed to spindle velocity in milling?
V = 7.1πD
How is the feed rate in milling calculated when given the feed per cutter tooth?
fr = NtNf
What is the formula to determine the material removal rate in a slab-milling operation?
RMR = wdf𝑟
How is the approach distance calculated to fully engage the cutter in a slab cutting operation?
A = d(D-d)
This quiz covers the theory of metal machining, specifically focusing on the process of milling where a workpart is fed past a rotating cylindrical tool with multiple cutting edges. Learn about the differences between milling and drilling, the role of milling machines, and the components involved in the milling process.
