Investigation of 3D Non-Contact Laser-Based Inspection Techniques for Application in Gear Metrology

Contact stylus type measuring methods using contact probes are today’s dominant industrial solution for gear metrology. Due to the difficulties of further improving those methods, new non-contact measuring systems have been developed in the past few years. The most promising option that meets the requirements of accuracy, repeatability and high cycle time is the 3D non-contact measurement method based on triangulation laser sensor. This thesis provides an evaluation of a non contact surface profilometer, using one of the contact technology currently employed by FCA gear metrology labs as a benchmark.
