G210. Bore milling canned cycle
9.16 G210. Bore milling canned cycle
This cycle may be used to increase the diameter of a hole through a helical movement of the tool.
Besides this, if the tool allows it, it is also possible to mill a hole without having to drill it first.
Working in Cartesian coordinates, the basic structure of the block is as follows:
G210 G98/G99 X Y Z D I J K B
[ G98/G99 ] Withdrawal plane
G98 The tool withdraws to the Initial Plane, once the hole has been milled.
G99 The tool withdraws to the Reference Plane, once the hole has been milled.
[X±5.5] Hole center coordinate along the abscissa axis.
It defines the hole center coordinate along the X axis. If not programmed, it will assume the current
tool position on that axis.
[ Y±5.5 ] Hole center coordinate along the ordinate axis
It defines the hole center coordinate along the Y axis. If not programmed, it will assume the current
tool position on that axis.
[ Z±5.5 ] Reference plane
Defines the reference plane coordinate. It may be programmed either in absolute or incremental
coordinates, in which case it will be referred to the starting plane.
If not programmed, it assumes as reference plane the current position of the tool.
[D5] Safety distance
Defines the distance between the reference plane and the surface of the part where the milling is
to be done. If not programmed, it assumes 0.
[ I±5.5 ] Machining depth
Defines the machining depth. It may be programmed either in absolute or incremental coordinates,
in which case it will be referred to the reference plane.
If not programmed, the CNC issues the corresponding error.
[J±5.5 ] Hole diameter
Defines the nominal diameter of the hole. The sign indicates the direction of the helical path
associated with the machining of the hole (positive if clockwise and negative if counterclockwise).
If not programmed or programmed with a value smaller than the diameter of the active tool, the CNC
issues the relevant error message.
[ K5.5 ] Pre-drilling diameter
Starting with a hole previously drilled, this parameter defines the diameter of that hole. If not
programmed or programmed with a 0 value, it means that no hole has been previously drilled.
