Inserting a chamfer between two straight lines
The chamfer enables you to cut off corners at the intersection of
two straight lines.
The line blocks before and after the
G24
block must be in the
same working plane as the chamfer.
The radius compensation before and after the
G24
block must
be the same
The chamfer must be machinable with the current tool
Chamfer side length
: Length of the chamfer, and
if necessary:
Feed rate F
(effective only in
G24
block)
Example NC blocks
N70 G01 G41 X+0 Y+30 F300 M3*
N80 X+40 G91 Y+5*
N90 G24 R12 F250*
N100 G91 X+5 G90 Y+0*
You cannot start a contour with a
G24
block.
A chamfer is possible only in the working plane.
The corner point is cut off by the chamfer and is not
part of the contour.
A feed rate programmed in the
G24
block is effective
only in that CHF block. After the
G24
block, the
previous feed rate becomes effective again.
