|
The volume of material/metal removed per unit of time is called
|
material removal rate |
|
An ideal condition that favors a continuous chip is using proper cutting speeds.
|
True |
|
The removal of material during the cut is measured in cubic inches per minute or cubic millimeters per minute. |
True
|

A coarse/heavy feed will contribute to the creation of continuous chips.
|
False |
|
The byproduct of material during the cutting process is called

A continuous chip is most likely seen on brittle materials being drilled or machined |
False |
|
The depth of cut should not exceed _________ of the cutting tool.
|
1/2 the diameter

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

A small or thin chip will transfer heat very well
|
False
|
|
Larger diameter tools require faster RPM speeds and smaller tools require slower RPM speeds
|
False
