G83. Deep-hole drilling canned cycle with constant peck
9.9 G83. Deep-hole drilling canned cycle with constant peck
This cycle makes successive drilling steps until the final coordinate is reached.
The tool withdraws as far as the reference plane after each drilling step.
Working in Cartesian coordinates, the basic structure of the block is as follows:
G83 G98/G99 X Y Z I J
[ G98/G99 ] Withdrawal plane
G98 The tool withdraws to the Initial Plane, once the hole has been drilled.
G99 The tool withdraws to the Reference Plane, once the hole has been drilled.
[ X/Y±5.5 ] Machining coordinates
These are optional and define the movement of the axes of the main plane to position the tool at
the machining point.
This point can be programmed in Cartesian coordinates or in polar coordinates, and the coordinates
may be absolute or incremental, according to whether the machine is operating in G90 or G91.
[ Z±5.5 ] Reference plane
Defines the reference plane coordinate. It can be programmed in absolute coordinates or
incremental coordinates, in which case it will be referred to the initial plane.
If not programmed, it assumes as reference plane the current position of the tool.
[ I±5.5 ] Depth of each drilling peck
Defines the value of each drilling step according to the axis longitudinal to the main plane.
