Canned cycle (boring cycle)
The control system enters into Feedrate mode when the tool reaches the hole bottom and the
spindle stops. In this condition, the tool may stroke by manual means. Any manual operation
may be performed. For the purpose of safety, however, the tool shall be withdrawn from the hole.
To restart machining, it is necessary to switch to DNC or automatic mode and press the CYCLE
START key. The spindle rotates forward after the tool returns to the position of starting point or
Point R through G98 and G99. Then the command of the next block is executed.
