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
426
Meaning
Measured position in
reference axis
Measured position in
secondary axis
Measured position in tool axis
Measured deviation in
reference axis
Measured deviation in
secondary axis
Measured deviation in tool
axis
Measured 3-D deviation
Less than 0: Undersize
Greater than 0: Oversize
Workpiece status:
–1= Not defined
0 = Good
1 = Rework
2 = Scrap
