81 HEIDENHAIN TNC 410, TNC 426, TNC 430
Entering tool data in tables
You can define and store up to 32767 tools and their tool data in a
tool table (TNC 410: 254 tools). In Machine Parameter 7260, you can
define how many tool places are to be reserved by the TNC when a
new table is set up. See also the Editing Functions at a later stage in
this Chapter. For the TNC 426, TNC 430 with the NC software
number 280 474-xx, in order to be able to assign various
compensation data to a tool (indexing tool number), machine
parameter 7262 must not be equal to 0.

You must use tool tables if
■ your machine tool has an automatic tool changer,
■ you want to measure tools automatically with the
TT 120 touch probe (only conversational
programming)
Abbr. Input
T Number by which the tool is called in the program
NAME Name by which the tool is called in the program
L Value for tool length compensation
R Compensation value for the tool radius R
R2 Tool radius R2 for toroid cutters
(only for 3-D radius compensation or graphical
representation of a machining operation with spherical or
toroid cutters, not TNC 410)
DL Delta value for tool length
DR Delta value for tool radius R
DR2 Delta value for tool radius R2 (not TNC 410)
LCUTS Tooth length of the tool for Cycle G122
ANGLE Maximum plunge angle of the tool for reciprocating
plunge-cut in Cycles G122 and G208
TL Set tool lock
(TL:Tool Lock
RT Number of replacement tool,
if available
(see also TIME2)
TIME1 Maximum tool life in minutes. This
function can vary depending on the individual machine
tool. Your machine manual provides more information
on TIME1.
TIME2 Maximum tool life in minutes during TOOL CALL.
If the current tool age exceeds this value,
the TNC changes the tool
during the next TOOL CALL
(see also CUR.TIME)
CUR.TIME Time in minutes the tool has been in use:
The TNC automatically counts
the current tool age.
A starting value can be entered for used tools.
