Minimal Basic Field Checks for Laser Tracker Systems
Minimal Basic Field Checks for Laser Tracker Systems Decision Matrix
Common Recommended Practices Minimal Basic Laser Tracker Field Checks § Assumption § System has been shipped overseas (airplane) § System has been shipped within a country (truck, airplane, car, …) § System has been moved from one to the other plant (truck, car, …) § System has been moved from one to the other working area (put on measurement cart or transportation in white shipping containers “disassembled”, …) Independent of the transportation way, we recommend a basic minimal test procedure. This recommendation is also applicable for daily work. 2 Unterentfelden 2007 -07 -18, D. Moser -785
Common Recommended Practices Minimal Basic Laser Tracker Field Checks Basic System Check 2 F-Measurement Setup: 2 @ -40°, separated horizontally by 90° (measurements on the floor) Two Face Field Check No BB-Measurement Setup: 1 @ 1 m (3 ft) Check OK ? Yes Ball Bar Field Check No Full Compensation IFM Field Check Yes Check OK ? IFM-Measurement Setup: use of IFM Distance Tool or 2 reflector positions at 3 m (10 ft) in horizon of tracker head Intermediate Compensation No Yes Check OK ? ADM Instrument Field Check IFM Compensation No ADM Instrument Compensation 3 Unterentfelden 2007 -07 -18, D. Moser -785 Check OK ? ADM-Measurement Setup: 1 @ 3. 5 m (11 ft) 1 @ largest working range Yes System in specification
Common Recommended Practices Tolerances for Laser Tracker Field Checks § Metric Ball Bar at < 1 m, bandwidth Ball Bar at < 3 m, bandwidth Two Face, bandwidth Bird Bath Distance (IFM) ADM Offset Instrument, residuals § Inches Ball Bar at < 3 ft, bandwidth Ball Bar at < 10 ft, bandwidth Two Face, bandwidth Bird Bath Distance (IFM) ADM Offset Instrument, residuals * Repeatability of two determinations 4 Unterentfelden 2007 -07 -18, D.
