Carbide Insert and Grade Selection

Coated inserts:

Generate lower cutting forces
Generate less friction
Leave a better finish
Offer better chip control than uncoated inserts

Question 1 of 10

Carbide Insert and Grade Selection

A subtle, but significant, cause of edge chipping and tool failure in cavity milling is:

Too much coolant
The wrong insert grade
Poor chip evacuation
Chatter

Question 1 of 10

Carbide Insert and Grade Selection

A milling insert in the “cermet” grade family:

Is resistant to a built-up edge
Is a good choice when finish milling
Allows coated carbide speeds without being coated
All of the above

Question 1 of 10

Carbide Insert and Grade Selection

A land that has a designation of “T” is:

Pre-dulling of the cutting edge
A large hone
A wiper flat
A negative land ground on the cutting edge

Question 1 of 10

Carbide Insert and Grade Selection

The maximum depth of cut in face milling is:

1/3 the available cutting edge
1/2 the available cutting edge
2/3 the available cutting edge
Equal to the inscribed circle of the insert

Question 1 of 10

Carbide Insert and Grade Selection

More heat is generated in a milling cut by:

Increasing the depth of cut
Increasing the cutting speed
Increasing the feed
Removing every other insert

Question 1 of 10

Carbide Insert and Grade Selection

Carbide is made from:

Tungsten and carbide
Cubic carbides
“Super” hardened steels
Tungsten carbide and other binder materials, such as cobalt, in powder form

Question 1 of 10

Carbide Insert and Grade Selection

Ceramic inserts:

Should never be used in milling applications
Can be used only in very light milling cuts
Can be used for milling but only with high pressure coolant
Must be run without any cutting fluid

Question 1 of 10

Carbide Insert and Grade Selection

Grades of carbide are usually classified by:

Heat-resistant cubic carbides
Hardness
Type of chip produced
Toughness

Question 1 of 10

Carbide Insert and Grade Selection

The corner configuration on a milling insert can affect:

Part finish, insert strength, and feed per rev of the cutter
Part finish, cutter speed, and burr thickness
Cutter speed, edge breakout, and part finish
None of the above

Question 1 of 10

Carbide Insert and Grade Selection

The first consideration when making an insert grade selection is the rigidity of the setup. What is the second consideration?

Horsepower
Workpiece material
Spindle speed of the machine
