Target window for digitizing contour lines with a measuring touch probe
When you are digitizing contour lines the
individual contour lines do not end exactly in their
starting points.
With machine parameter MP6390 you can define
a square target window within which the end
point must lie after the touch probe has orbited
the model. Enter half the side length of the target
window for the side length.

connection with MP6570
Feed rate for probing a stationary tool with the TT 120
Radius measurement with the TT 120: Distance from lower edge of tool to upper edge of stylus
