Applying the tool usage test
With the TOOL USAGE and TOOL USAGE TEST soft keys, you can

check before starting a program in a Program Run operating mode

whether the tools being used in the selected program have enough

service life remaining. The TNC then compares the actual service-life

values in the tool table with the nominal values from the tool usage

file.
After you have pressed the TOOL USAGE TEST soft key, the TNC

displays the result of the tool usage test in a pop-up window. Use the

CE key to close the pop-up window.
The TNC saves the tool usage times in a separate file with the

extension pgmname.H.T.DEP. (see "Changing the MOD setting for

dependent files" on page 579). The generated tool usage file has the

following information:

Column

Meaning

TOKEN

TOOL

: Tool usage time per TOOL CALL. The

entries are listed in chronological order.

TTOTAL

: Total usage time of a tool

STOTAL

: Call of a subprogram (including

cycles). The entries are listed in

chronological order.

TIMETOTAL

: The total machining time of the

NC program is entered in the WTIME column.

In the PATH column the TNC saves the path

name of the corresponding NC programs.

The TIME column shows the sum of all TIME

entries (only when the spindle is on, and

without rapid traverse). The TNC sets all

other columns to 0

TOOLFILE

: In the PATH column, the TNC

saves the path name of the tool table with

which you conducted the Test Run. This

enables the TNC during the actual tool

usage test to detect whether you

performed the test run with the TOOL.T

TNR

Tool number (–1: No tool inserted yet)

IDX

Tool index

NAME

Tool name from the tool table

TIME

Tool-usage time in seconds (feed time)

WTIME

Tool-usage time in seconds (total usage time

between tool changes)

RAD

Tool radius R

+ Oversize of tool radius DR

from the tool table. The unit is 0.1 µm.
