1Fixtures are designed to
- Alocate the work quickly and accurately
- Bprovide support for the part
- Creproduced the same part within specified limits.
- Dcontain no setting blocks or cutter-setting gages
- Efacilitate chip removal and coolant drainage
2The most common fixtures are lathe and milling
- ATrue
- BFalse
3Fixtures must reference the cutting tool
- ATrue
- BFalse
4Some of the common types of fixtures are:
- APlate Fixture
- BChannel Fixture
- CAngle Plate Fixture
- DVise-Jaw Fixture
- ELeaf Fixture
- FIndexing Fixture
5Vise-Jaw Fixture is used to machine large parts
- ATrue
- BFalse
6The plate fixture is the most versatile and common
- ATrue
- BFalse
7For a vise-jaw fixture, standard vise jaws are replaced with jaws that are formed to fit the part
- ATrue
- BFalse
8Tool setting block surfaces must be made smaller than the part surfaces
- ATrue
- BFalse
9Some key components that are on a fixture
- ASetting block
- BLocators
- CClamps
- DBushings
10Locators must locate the part and restrict the part movement when milling
- ATrue
- BFalse
11Which are true setting blocks & feeler gauges
- AThey set the relationship between the work and
the tool for machining operations such as milling, turning, and grinding - BSet blocks are normally located away from the fixture
- Cfeeler gauges to insure the proper clearance prevents damage and wear to the set block when setting the cutter
- DThe surface used to reference the cutter is controlled by the type of operation being performed.
- ESetting blocks are also known as setup gauges
- AThey set the relationship between the work and
12The basic plate fixture is a simple plate on which the part is mounted,
located, and held with a variety of tooling details- ATrue
- BFalse
13Fixture keys references slots on the milling machine
- ATrue
- BFalse
14The best material for locators is carbide steel
- ATrue
- BFalse
15A secondary locator is used to prevent rotation if the part is circular
- ATrue
- BFalse
16Clamps hold the workpiece against the direction of the milling toolpath
- ATrue
- BFalse
17Secondary cutting forces are those generated as the cutter leaves the workpiece
- ATrue
- BFalse
18The only purpose of clamps is to maintain the position of the workpiece against the locators and resist the secondary cutting forces
- ATrue
- BFalse
19There is no such thing as too much clamping force
- ATrue
- BFalse
20Surface damage is often caused by clamps with hardened or non-rotating contact surfaces
- ATrue
- BFalse
21In all fixtures, it is important to direct the cutting forces into the locators
- ATrue
- BFalse
22Vise clamps are designed for precision clamping on knee-type mills, grinders, and CNC machines
- ATrue
- BFalse
23Which are common clamps for a fixture:
- AStrap Clamps
- BVise Clamps
- CSwing Clamps
- DToggle Clamps
- ECam action clamp
24Which are common types of strap clamps
- AHinge Clamp
- BSwing Clamp
- CLatch Clamp
- DSliding Clamp
- EStrap Clamp-single end & hand knob
- FStrap Clamp-double end & hand knob
25To determine the drill size for a ream, leave 1/32 under for reaming
- ATrue
- BFalse
26Max Clearance = Max Hole - Min Shaft
- ATrue
- BFalse
27Minimum Clearance = Min Hole - Max Hole
- ATrue
- BFalse
28The safety factor is usually 2 when calculating the required clamping force
- ATrue
- BFalse
29To calculate the required clamping force:
= [(heaviest cut horsepower) X (machine efficiency) X 33 000] / cutting speed- ATrue
- BFalse
30To calculate the cutting force:
= (cutting force/static friction coefficient) X safety factor- ATrue
- BFalse
31Plug gauge is a quick, accurate way of checking that a hole is within the specified tolerance.
- ATrue
- BFalse
32Plug gauges can measure the hole diameter
- ATrue
- BFalse
33Most plug gauges are made with a go end and a no-go end
- ATrue
- BFalse
