Chat with AIExam 9: Hole-Making Cycles
What is peck drilling?
(88) 
VerifiedPeck drilling is similar to a standard drilling cycle except that the tool is backed out of the hole at certain intervals to clear the chips and cool the tool. Almost every deep hole will need to be peck drilled in order to maintain a reasonable tool life. This is particularly true when using HSS drills that cannot handle as much heat as carbide. In fact, the G83 cycle is used much more often than the standard G81 drilling cycle for the average machining application.
What happens if you must program canned cycles in incremental coordinates?
(72) VerifiedThe need may occasionally arise to program canned cycles in incremental coordinates. In this situation, a couple of changes will need to be made for the canned cycle to perform properly:
1. The retract plane will be set as an incremental distance from the initial plane.
2. The Z-depth will be set as the incremental distance from the retract plane to the bottom of the hole.
Q is an incremental distance used to specify the ____ depth.

The ____-word is used to indicate the number of times a cycle should be repeated executed.
(75) ____ cycles were developed to perform common tasks that would require many lines of standard code to accomplish.
(55) Loops are a good time saver, and they can lead to very elegant programs.
(76) There are two important planes that we must consider when using hole-making cycles: the initial plane and the ____ plane.
(85) A normal drilling cycle will retract the tool as soon as the ____-level is reached.
(90) Canned cycles save time because they can be accessed with a single block of code.
(71) Boring operations use an eccentric boring head that can be adjusted to the proper radius with a screw.
