HEIDENHAIN NC 124 - Manual (Page 28)

3 Manual Operation and Setup
28 TNC 124
Entering tool length and radius
Enter the lengths and radii of your tools in the TNC's tool table. The
TNC will then take the entered data into account for datum setting
and all other machining processes.
You can enter up to 99 tools.
The tool length is the difference in length DL between the tool and
the zero tool.
To enter the tool length directly move the tool until it touches the
workpiece and transfer the tool position coordinate by using the “ac-
tual position capture” function.
Sign for the length difference DL
If the tool is longer than the zero tool: DL > 0
If the tool is shorter than the zero tool: DL < 0
Example: Entering the tool length and radius
into the tool table
Tool number: e.g. 7
Tool length: L = 12 mm
Tool radius: R = 8 mm
