  • 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. 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

2. A groove or channel cut in a shaft

3. 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

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

5. 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

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

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

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

9. 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

10. 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.

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

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

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

14. 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).

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

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

17. 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.

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

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