at work feedrate (G01)
9.15 G89. Boring cycle with withdrawal at work feedrate (G01)
This cycle bores at the point indicated until the final programmed coordinate is reached.
It is possible to program a dwell at the bottom of the machined hole.
Working in Cartesian coordinates, the basic structure of the block is as follows:
G89 G98/G99 X Y Z I K
[ G98/G99 ] Withdrawal plane
G98 The tool withdraws to the Initial Plane, once the hole has been bored.
G99 The tool withdraws to the Reference Plane, once the hole has been bored.
[ 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 ] Machining depth
Defines boring depth. It can be programmed in absolute coordinates or incremental coordinates and
in this case will be referred to the reference plane.
[ K5 ] Dwell
Defines the dwell, in hundredths of a second, after boring until the withdrawal begins. If not
programmed, the CNC will take the value of "K0".
