Straight line in rapid traverse G00 Straight line with
feed rate G01 F
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.
Coordinates of the end point of the straight line, if
necessary
Radius compensation
Feed rate F
Miscellaneous function M
Movement at rapid traverse
You can also use the L key to create a straight line block for a rapid
traverse movement ( G00 block):
Press the L key to open a program block for a linear movement
Press the left arrow key to switch to the input range for G codes
Press the
G0 soft key if you want to enter a rapid traverse
movement
Example NC blocks

Capture actual position
You can also generate a straight-line block ( G01 block) by using the
actual-position-capture key:
In the Manual Operation mode, move the tool to the position
you want to capture
Switch the screen display to Programming and Editing
Select the program block after which you want to insert the L
block
Press the actual-position-capture key. The TNC
generates an L block with the actual position
coordinates.
