Roll Angle in 6DOF Tracking

Volume 3, Issue 2

Stephen Kyle

In a 3D polar measurement system which tracks a probing device in 6 degrees of freedom (6DOF), the probe’s roll angle can be identified as a critical parameter in some system design concepts. This paper reviews methods and proposals for roll angle...

Wing Interior Structure Measurement Solution: Rotating Laser Scanner–Tracker Integration

Volume 3, Issue 2

Scott Waltari, Edward Sergoyan, Scott Sandwith

Validating the interior structure of a wing is a measurement challenge. Solving it cost-effectively meant integrating two precision metrology systems with a robotic controlled crawler and using software to couple them all together. A wing’s interior...

Complete, Practical, and Rapid Calibration of Multi-Axis Machine Tools Using a Laser Tracker

Volume 2, Issue 2

Philip Freeman

Many assembly and manufacturing processes can be viewed as moving a tool through a workspace using a kinematic mechanism; from the welding of car bodies, to the drilling of aircraft, to the machining of complex parts. Various unique mechanisms exist, but...

Integrating Certified Lengths to Strengthen Metrology Network Uncertainty

Volume 2, Issue 2

Joseph Calkins, Scott Sandwith

Calibrated and traceable scale lengths add significant value to 3D metrology networks. The primary benefit is to provide an observed physical standard with a documented uncertainty within the measurement process. This leads to an assumption that the object...
