Question 4

What happens if you must program canned cycles in incremental coordinates?

Question 5

Drilled holes are typically specified as the ____ depth.

A) full diameter
B) point
C) half radius
D) blunt

Question 6

Canned cycles and their associated parameters are modal.

Question 7

Q is an incremental distance used to specify the ____ depth.

A) point
B) radial
C) peck
D) full diameter

Question 8

Canned cycles save time because they can be accessed with a single block of code.

Question 9

A normal drilling cycle will retract the tool as soon as the ____-level is reached.

A) G
B) X
C) Y
D) Z

Question 10

What is the procedure for spindle orientation?

Question 11

What is the purpose of a drilling cycle with dwell?

Question 12

What is peck drilling?

Question 13

Which of the following is true about the G86 boring cycle?

A) Same as G85, but with a dwell at the bottom of the hole
B) Same as G87, but with a dwell at the bottom of the hole
C) The spindle will stop at the bottom of the hole, and then the tool must be retracted manually
D) Tends to leave a vertical tool mark along the wall

Question 14

Boring operations use an eccentric boring head that can be adjusted to the proper radius with a screw.

Question 15

How will the machine behave when a hole-making cycle is called?

Question 16

The Q-word is used to specify the dwell time.

Question 17

Loops are a good time saver, and they can lead to very elegant programs.

Question 18

There are two important planes that we must consider when using hole-making cycles: the initial plane and the ____ plane.

A) rotation
B) retract
C) resolution
D) revolution

Question 19

Which of the following is true about the G76 boring cycle?

A) Orients the tool at the bottom of the hole and then shifts slightly away from the wall before being retracted at rapid speed
B) Same as G87, but with a dwell at the bottom of the hole
C) Standard boring cycle
D) Tends to leave a vertical tool mark along the wall

Question 20

____ cycles were developed to perform common tasks that would require many lines of standard code to accomplish.

A) Clock
B) MCU
C) Canned
D) Unfixed
