Industrial Automated Lasertracker Application

Abstract

Large-Volume Metrology (LVM) provides abilities to reduce or remove jigs and fixtures throughout aerospace and automotive applications. Flexibility and versatility is raised substantially by using just universal (sensor less) grippers and smaller sized robots. The drawback of using LVM for applications like Best-Fit Part Assembly (automotive) or Stringer Integration for the A350-XWB (aerospace, presented last year at CMSC) already being offered by FFT is the dependence on measurement systems, which are historically developed and defined by being portable and mainly used manually in “suitable” environments. FFT raises availability levels during production for lasertrackers to be used in automated systems without surveillance by specially trained metrology staff. Lasertrackers are suitable to measure 3DoF (degrees-of-freedom) or 6DoF at high frequency with traceable precision and may scan complete surfaces meeting most metrological requirements of aerospace and automotive applications. They are used for automated part inspection and quality assurance throughout production systems and have proven to be robust and enduring parts of such. Several actions are currently performed by FFT to use trackers not only in bypassing stations, being their primary integration scenario currently, but in the critical path of an automated production, only covered by several minutes of self-learning trending predictors in case of failure or breakage.
