7.4 Corner rounding, radius blend, (G36)
G36 may be used to round a corner with a particular radius without
having to calculate either the center or the starting and ending points
of the arc.
Programming
The rounding definition must be programmed between the two paths
that define the corner to be rounded. These paths may be linear and/
or circular.
The programming format is "G36 I<radius>", where the radius value
is programmed in millimeters or in inches, depending on which are the
active units.
Considerations
The "I" value of the rounding radius remains active until another value
is programmed, therefore, it won't be necessary to program it in
successive rounding operations with the same radius.
The "I" value of the rounding radius is also used by functions:
G37 (Tangential entry) as entry radius.
G38 (Tangential exit) as exit radius.
G39 (corner chamfering) as size of the chamfer.
This means that the rounding radius set in G36 will be the new value
of the entry radius, exit radius or chamfer size when programming one
of these functions or vice versa.
