Training: Optical measurements and measurement systems for gears and rotary axes

The mechanical components of Wind Energy Systems (WES) are exposed to high loads transmitted to the drivetrain’s components. Therefore, the requirements on these parts are high and this often results in tight manufacturing tolerances related to their size and mass. Reliable verification of manufacturing tolerances through accurate measurements is a critical part of quality assurance. This training course is targeted at industry personnel, and it will describe the capabilities of various optical measurement systems as well as calibration strategies of rotary axes. The main focus will be on optical measurements of WES components, but the procedures may also be transferred to other industrial parts.

The training is free of charge and you can enroll by a short e-mail to:
