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 14.1 (a) lists canned cycles.
