103 HEIDENHAIN TNC 410, TNC 426, TNC 430
Straight line at rapid traverse G00
Straight line with feed rate G01 F . . .
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.
1 ú Enter the coordinates of the end point.
Further entries, if necessary:
ú Radius compensation G40/G41/G42
ú Feed rate F
ú Miscellaneous function M
Example NC blocks
N70 G01 G41 X+10 Y+40 F200 M3 *
N80 G91 X+20 Y-15 *
N90 G90 X+60 G91 Y-10 *
Inserting a chamfer 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 G24 block must be in the same
working plane.
■ The radius compensation before and after the G24 block must be
the same.
■ An inside chamfer must be large enough to accommodate the
current tool.
24 ú Confirm your entry with the ENT key.
ú Chamfer side length: Enter the length of the chamfer
ú Feed rate F (effective in G24 block only)
Example NC blocks
N70 G01 G41 X+0 Y+30 F300 M3 *
N80 X+40 G91 Y+5 *
N90 G24 R12 *
N100 X+5 G90 Y+0 *
You cannot start a contour with a G24 block!
A chamfer is possible only in the working plane.
The feed rate for chamfering is taken from the preceding
block.
The corner point is cut off by the chamfer and is not part
of the contour.
