Corner rounding RND
The
RND
function is used for rounding off corners.
The tool moves on an arc that is tangentially connected to both the
preceding and subsequent contour elements.
The rounding arc must be machinable with the called tool.
Rounding radius
: Enter the radius of the arc, and if
necessary:
Feed rate F
(effective only in the
RND
block)
Example NC blocks
5 L X+10 Y+40 RL F300 M3
6 L X+40 Y+25
7 RND R5 F100
8 L X+10 Y+5
In the preceding and subsequent contour elements,
both coordinates must lie in the plane of the
rounding arc. If you machine the contour without
tool-radius compensation, you must program both
coordinates in the working plane.
The corner point is cut off by the rounding arc and is
not part of the contour.
A feed rate programmed in the
RND
block is effective
only in that
RND
block. After the
RND
block, the
previous feed rate becomes effective again.
You can also use an
RND
block for a tangential
contour approach.
