The plunge grinding cycle consists of six operation sequences.
Operations (1) to (6) are repeated until the depth reaches the total depth
of cut specified at address K. In the single block stop mode, operations
(1) to (6) are performed every cycle start.
(1)Cutting is performed along the Y–axis in cutting feed mode for the
amount specified by I (depth of cut 1). The feedrate is specified by R.
(2)Dwell is performed for the time specified by P.
(3)Cutting feed is performed for the amount specified by X (or Z). The
feedrate is specified by F.
(4)Cutting is performed along the Y–axis in cutting feed mode for the
amount specified by J (depth of cut 2). The feedrate is specified by R.
(5)Dwell is performed for the time specified by P.
(6)Feeding is performed in the reverse direction for the amount specified
by X (or Z) at a feedrate specified by F.
