Straight line L
The tool moves on a straight line from its current position to the line
end point. The starting point is the end point of the preceding block.
ú Enter the coordinates of the end point.
Further entries, if necessary:
ú Radius compensation RL/RR/R0
ú Feed rate F
ú Miscellaneous function M
Example NC blocks
7 L X+10 Y+40 RL F200 M3
8 L IX+20 IY-15
9 L X+60 IY-10
Inserting a chamfer CHF between two straight lines
The chamfer enables you to cut off corners at the intersection of
two straight lines.
■ The blocks before and after the CHF block must be in the same
working plane.
■ The radius compensation before and after the chamfer block must
be the same.
■ An inside chamfer must be large enough to accommodate the
current tool.
ú Chamfer side length: Enter the length of the
chamfer
Further entries, if necessary:
ú Feed rate F (only effective in CHF block)
Example NC blocks
7 L X+0 Y+30 RL F300 M3
8 L X+40 IY+5
9 CHF 12
10 L IX+5 Y+0
You cannot start a contour with a CHF block
A chamfer is possible only in the working plane.
If you have not programmed a feed rate in the CHF block,
the TNC will move at the last programmed feed rate.
A feed rate programmed in the CHF block is effective
only in that block. After the CHF block, the previous feed
rate becomes effective again.
The corner point is cut off by the chamfer and is not part
of the contour.
