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 in the

central tool file TOOL.T by the delta value DR = 0. If

you wish to inspect a tool, the TNC compares the

measured radius with the tool radius R that is stored

in TOOL.T. It then calculates the positive or negative

deviation from the stored value and enters it into

TOOL.T as the delta value DR. The deviation can also

be used for Q parameter Q116. If the delta value is

greater than the permissible tool radius tolerance 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 (RTOL exceeded)

2.0

: Tool is broken (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).
