The relationship between the sizes of two mating parts is called the:
Class of Fit
HMIS stands for:
Hazardous Material Identification System
This is the process of verifying the accuracy of a measuring tool with another tool having a higher degree of precision that is known to be properly functioning and accurate, and making adjustments.
Calibration
What are GMPs and SOPs?
Good Manufacturing Practice
Standard Operating Procedure
What type of hardening operation that leaves the inner core in a softer condition is sometimes performed on medium-carbon steel?
Surface hardening
This is the minimum amount of clearance, or the maximum amount of interference between two mating parts that are features of size.
Allowance
In the Hazardous Materials Classification the blue, red, yellow, and white diamonds each stand for what?
Blue: Health hazards
Red:Flammability hazards
Yellow:Instability hazards
White:Special hazards
The vernier caliper can be used for measurements as small as:
0.001 or 0.02mm
What are the UCL and LCL and why are they important?
Upper control limit and lower control limit.
X-Bar chart shows that the machining process is in "control" because the average of the subgroups is well within the UCL and LCL.
The ability of a cutting fluid to reduce friction is called:
Lubricity
In softer metals such as aluminum, particles of the material of the material being filed can embed in the teeth. This is called:
Pinning
Put these fractions in correct numerical order:
7/32, 1/4, 5/8, 37/64, and 13/16
7/32, 1/4, 37/64, 5/8, 13/16
p. 60-61
What are the two factors generally considered when discussing surface finish?
Roughness and waviness
This type of steel is formed below red-hot temperature by being pulled through rollers and has a smooth gray surface.
Cold-rolled steel
What hardness testing scale uses many different penetrators and loads?
Rockwell Hardness Scale
This is the narrow slot produced when sawing.
Kerf
What is the inch equivalent of 37.3mm?
1.4685 inches
What are the two basic types of indicator movements?
Plunger type and lever-type movement
What are the four basic parts of a process plan?
1) Material Selection
2) Machine Selection and Workholding
3) Tooling Selection
4) Speed and Feed Calculation
When steel is machined ingredients are added to improve the oil's performance. One common additive is called what?
Wetting Agent
The sharp point on a file is called the:
Tang
What is the circumference of a circle that has a radius of 2?
4 pi
What is the smallest graduation on both an inch and a metric micrometer?
.025 inches
0.5 mm
If an X-bar chart graph is between the LCL and UCL, a machining process is said to be?
Likewise, if an X-bar chart falls below the LCL or rises above the UCL, a machining process is said to be?
1) In Control
2) Out of Control
What two ingredients are often used as additives to improve lubrication of cutting oils?
Sulfur and chlorine
