Canned cycles make it easier for the programmer to create programs.
With a canned cycle, a frequently–used machining operation can be
specified in a single block with a G function; without canned cycles,
normally more than one block is required. In addition, the use of canned
cycles can shorten the program to save memory.
Table 2.1 (a) lists canned cycles.

A canned cycle consists of a sequence of six operations (Fig.2.1)
Operation 1 Positioning of axis X
(including also another axis)
Operation 2 Rapid traverse up to point R level
Operation 3 Hole machining
Operation 4 Operation at the bottom of a hole
Operation 5 Retraction to point R level
Operation 6 Rapid traverse up to the initial point
