This tool projects a magnified image of a part on a screen for measurement.
Optical comparator
This can be defined as the creation of a system of activities used to make sure a customer's needs are met.
Quality Assurance
What do SAE,ASTM, and IADS stand for? What is the problem with having so many systems for identifying metals, and how is it remedied?
Society of Automotive Engineers, American Society for Testing and Materials, and International Alloy Designation System
Unified Numbering System
Direct hardening can be performed on steel containing at least?
0.3% carbon
What is the pump attached to the central reservoir on the side of a machine that contains lubricant called?
One shot
This tool features movement in two or three directions through the use of micrometer dials to obtain measurements. Measurements can be taken directly from the micrometer dials or by using software connected to a computer.
Toolmaker's microscope
This states how many parts should be inspected from a given batch or during a given time period.
Sampling plan
What ranges of carbon content are low, medium, and high-carbon steels?
Low:0.05-0.3
Medium:0.3-0.5
High:0.5-1.5
Flame hardening and induction hardening are examples of what?
Surface hardening
Machine tools use dovetail-shaped slides that contain a tapered wedge or ____?
Gib
This tool identifies locations in an x,y,z coordinate system.
Coordinate measuring machine
This tells what dimensions to inspect and what measuring tools and processes to use during inspection.
Inspection plan
Engine blocks and machine tool bases are often machined from?
Cast iron
The difference between annealing and normalizing is?
Faster cooling provides different results even though temperatures are pretty close
Straight oils are only used on what type of metal?
Nonferrous
The most widely used system for measurement of surface finish and roughness is called?
Ra
This is the name given to the actions of inspecting dimensions to make tolerances are met.
Quality control
Brass and Bronze are composed of?
Brass:Alloy of copper and zinc
Bronze: Alloy of copper and tin
Precipitation heat treatment heats what metal to what degree?
Aluminum, 300 degrees
There are several alternatives to liquid oils and synthetics. Name one.
Cold air gun
Solid and semi-solid cutting compound
This tool shows small movements by displaying them with a needle on a graduated dial face.
Dial indicator
What are the UCL and LCL?
Upper control limit and lower control limit. When X-bar chart stays between the ucl and lcl, the process is said to be in control.
This metal has the best strength-to-weight ratio of any metal.
Titanium
What are the Rockwell hardness scales? Which use a Brale?
A, B, and C. A and C use a Brale.
Semi-synthetics are crosses between?
Soluble oils and synthetics
