Carbide Insert and Grade Selection

Coated inserts:

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

Question 1 of 10

Carbide Insert and Grade Selection

Carbide is made from:

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

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 corner configuration on a milling insert can affect:

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

Question 1 of 10

Carbide Insert and Grade Selection

A milling insert in the “cermet” grade family:

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

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?

Spindle speed of the machine
Horsepower
Workpiece material

Question 1 of 10

Carbide Insert and Grade Selection

Grades of carbide are usually classified by:

Toughness
Type of chip produced
Heat-resistant cubic carbides
Hardness

Question 1 of 10

Carbide Insert and Grade Selection

The maximum depth of cut in face milling is:

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

Question 1 of 10

Carbide Insert and Grade Selection

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

Chatter
Poor chip evacuation
The wrong insert grade
Too much coolant

Question 1 of 10

Carbide Insert and Grade Selection

More heat is generated in a milling cut by:

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

Question 1 of 10

Carbide Insert and Grade Selection

Ceramic inserts:

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
Should never be used in milling applications
