Hole-machining canned cycles (G80 to G89)

Hole-machining canned cycles (G80 to G89) can define specific movements for
machining holes that usually require several blocks of commands by single-block
commands. G80 cancels the called out canned cycle program.
G codes that call out canned cycles G80 to G89 are common for all G code sy-
stems.
G codes calling canned cycles and axis movement patterns of canned cycles
G codes that call out a canned cycle and the axis movement pattern of the called
canned cycle are indicated in Table 4-4.

When using canned cycles the sequence of operations is generally carried out as
described below:
Operation 1 -- Positioning of X (Z) and C axis
Operation 2 -- Rapid traverse movement to level R
Operation 3 -- Hole machining
Operation 4 -- Operation at hole bottom
Operation 5 -- Retraction to R level
Operation 6 -- Rapid retraction to the initial point
