Chip Formation, Load, And Material Removal Rates

Front 1

Chip load is equal to the amount of material cut by ______ edge(s) during one revolution of the cutter.

Back 1

One

Front 2

The volume of material/metal removed per unit of time is called

Back 2

material removal rate

Front 3

An ideal condition that favors a continuous chip is using proper cutting speeds.

Back 3

True

Front 4

The removal of material during the cut is measured in cubic inches per minute or cubic millimeters per minute.

Back 4

True

Front 5

A low surface feet-per-minute or poor shearing action of the work piece material will cause

Back 5

built-up edge

Front 6

A coarse/heavy feed will contribute to the creation of continuous chips.

Back 6

False

Front 7

The byproduct of material during the cutting process is called

Back 7

chips

Front 8

A continuous chip is most likely seen on brittle materials being drilled or machined

Back 8

False

Front 9

The depth of cut should not exceed _________ of the cutting tool.

Back 9

1/2 the diameter

Front 10

If a cutting tool is fed through aluminum, while slotting. 8 ipm for a distance of 12.5" with an approach and departure distance of 1/2", what is the total cutting time for this one cut?

Back 10

1 min 41 sec

Front 11

Chip load refers to the thickness of a chip formed during machining of a material

Back 11

True

Front 12

You are curios to see the material removal rate while machining aluminum. You have set your depth of cut at 0.125" using a 1 inch flat endmill. Your width of cut is only 0.75" of the total 1 inch during the cut. You have set your feed rate at 15 ipm. What is the MRR of this process?

Back 12

1.41 in^3

Front 13

A design in the geometry of the cutting tool that rolls the chip into a tight number nine shape us called

Back 13

chip breaker

Front 14

A small or thin chip will transfer heat very well

Back 14

False

Front 15

Larger diameter tools require faster RPM speeds and smaller tools require slower RPM speeds

Back 15

False
