HEIDENHAIN TNC 426 B, TNC 430
Straight line L
The TNC moves the tool in a straight line from its current position
to the straight-line end point. The starting point is the end point of
the preceding block.
ú
Enter the coordinates of the end point for the line.
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
Actual position capture
You can also generate a straight-line block (L block) by using the
actual-position-capture key:
ú
In the Manual Operation mode, move the tool to the position you
wish to capture.
ú
Switch the screen display to Programming and Editing.
ú
Select the program block after which you want to insert the L
block.
ú
Press the actual-position-capture key: The TNC
generates an L block with the actual position
coordinates.
In the MOD function, you define the number of axes that
the TNC saves in an L block (see Chapter 14 ”MOD
Functions,” section ”Selecting the Axes for Generating L
Blocks”).
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)
