DBB Guidebook - NC-program
DBB measurement could be done by the following NC-program. This program has been made for Fanuc series NC-controls and measuring parameters are:
Radius of the ballbar: 150 mmRadius of the measuring circle: 150 mm
Feedrates: 400 mm and 2000 mm
Cyrcles: first CW and then CCW (both 360°)
Measuring plane: XY
By pressing underlined line, you can see the picture of machine tools current position.
