System parameter
The TNC stores the results of the probing process in the following
parameters:
System parameter Meaning
Q151 Measured position in
reference axis
Q152 Measured position in
secondary axis
Q153 Measured position in tool axis
Q161 Measured deviation in
reference axis
Q162 Measured deviation in
secondary axis
Q163 Measured deviation in tool
axis
Q164
Measured 3-D deviation
Less than 0: Undersize
Greater than 0: Oversize
Q183
Workpiece status:
–1= Not defined
0 = Good
1 = Rework
2 = Scrap
Log function
Once probing has finished, the TNC generates a log in HTML
format. The TNC saves the log in the same folder in which the *.h
file is located (as long as no path is configured for FN16).
The log includes the following contents:
Defined nominal coordinate
Ascertained actual coordinate
Colored display of the values (green for "good," orange for
"rework," red for "scrap")
(If a tolerance QS400 was defined) Upper and lower allowances
are output, as well as the determined deviation along the normal
vector
Actual probing direction (as a vector in the input system). The
value of the vector corresponds to the configured probing path
