  • Answer 19 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A conical feature in the end of a machined hole. Used to recess the conically shaped head of a fastener - such as a flathead machine screw

2. (or boring) process for enlarging an existing hole.

3. A small-radius outside corner formed between two surfaces - a rounded exterior corner

4. Secures metal to a carriage and feeds it to a rotating cutter that shapes the metal. It creates flat and angular surfaces and grooves on the metal. Most versital tool

5. Used to enlarge the end(s) of a machined hole to a specified diameter and depth

6. The shaft and key are inserted into a hub - wheel - or pulley where the key mates with a groove

7. Used to machine new holes of enlarge existing holes in material.

8. A machine part that is used as a positive connection for transmitting torque between a shaft and a hub - pulley - or wheel

9. Used to enlarge of finish a hole that has been drilled - bored - of cored.

10. Process that uses chemicals to remove material accurately. Chemicals are placed on the part to be removed and the other parts are protected. Ex: Electrochemical - ultrasonic machining - laser machining

11. A groove or channel cut in a shaft

12. A slight angle used to relieve a sharp corner or to assist an entry of a pin or thread

13. Better known as a drill press - is used to machine-drill holes in material. Other drilling operations are performed such as reaming - boring - countersinking - counter boring - and tapping.

14. Used primarily for the production of horizontal - vertical - or angular flat surfaces. Is being replaced by the milling machine

15. Slightly rounded curves at corners - helps to distribute stress more equally throughout the part - a rounded interior corner to help strengthen

16. A milling machine with a worktable that can be swiveled for milling helical work. It is always supplied with attachments - including an indexing fixture. Table action and rotary head can go along all three axes (x - y - and z).

17. Used to cut material by turing cylindrically shaped objects.

18. AKA grinder - used to remove materials by rotating an abrasive wheel. Usually used when a smooth - acurate surface finish is required. Honing and laping made extremely smooth and acurate surface finishes. Variety of grindng machine types.

19. May be used as cutoff tools to establish the length of material for further machining. Ex: abrasive saw - tube saw - power band saw - power hacksaw - water jet
