NIMS measurement material and safety

1) The safest way to remove chips from a lathe or milling machine is to use a: 

• a) Air hose and high pressure nozzle 
• b) Glove covering the operator’s hand 
• c) Shop rag soaked in solvent 
• d) Brush 

If a vertical mill table is loose and has side play, the best solution to alleviate side play is to: 

• Tighten the clamps that lock the table 
• Tighten the taper gib adjustment 
• Loosen the taper gib adjustment 
• Use a parallel clamp and angle plate to eliminate any movement

Thread percentage is dependent on the: 

• Major diameter of the thread
• Number of threads per inch 
• Thread angle
• Tap hole diameter 

A reaming operation produces finish tears. The cause of the tears is: 

• Newly sharpened reamers 
• Insufficient stock allowance 
• Feeding too slow 
• A reamer with a worn tip

What is the most common type of surface finish callout? 

• Roughness
• Waviness 
• Cut band length 
• Lay 

Inspection plans are needed to: 

• Coordinate inspection procedures
• Identify measuring tools 
•  Check dimensions in a repeatable and reliable way
• All of the above 

Tight threads produced by a tapping operation may be caused by

• Material springback 
• Tap wear
• Large tap hole diameter
• The tap cutting edges being too sharp

What does the acronym FN represent? 

• Fast fit
• Frontal fit 
• Force fit
• Fundamental fit

The acronym MSDS means: 

• Machine Shop Disposal System
•  Material Safety Data Sheet 
• Manual Safety Data System 
•  Multiple System Diagnostic Sheet

The first course of action to take if a material (solid) becomes lodged in the eye is to

• Use light air pressure to blow out the debris 
• Use a magnet to attract the object
•  Rub the eye in a circular motio
• Pull the top lid over the bottom lid
