Cycle parameters

Measure tool=0 / Check tool=1:

Select whether the

tool is to be measured for the first time or whether a

tool that has already been measured is to be

inspected. If the tool is being measured for the first

time, the TNC overwrites the tool radius R and the

tool length L in the central tool file TOOL.T by the

delta values DR = 0 and DL = 0. If you wish to inspect

a tool, the TNC compares the measured data with the

tool data stored in TOOL.T. The TNC calculates the

deviations and enters them as positive or negative

delta values DR and DL in TOOL.T. The deviations are

also available in the Q parameters Q115 and Q116. If

the delta values are greater than the permissible tool

tolerances for wear or break detection, the TNC will

lock the tool (status L in TOOL.T).

Parameter number for result?:

Parameter number in

which the TNC stores the status of the

measurement:

0.0

: Tool is within the tolerance

1.0

: Tool is worn (LTOL or/and RTOL exceeded)

2.0

: Tool is broken (LBREAK or/and RBREAK exceeded).

If you do not wish to use the result of measurement

within the program, answer the dialog prompt with

NO ENT.

Clearance height:

Enter the position in the spindle

axis at which there is no danger of collision with the

workpiece or fixtures. The clearance height is

referenced to the active workpiece datum. If you

enter such a small clearance height that the tool tip

would lie below the level of the probe contact, the

TNC automatically positions the tool above the level

of the probe contact (safety zone from MP6540).
