Paper Abstract

An automatic technique for gear reconstruction is presented. In this technique, the gear modeling is performed by means of an approximation network. To carry it out, a vision system is implemented based on laser metrology. The approximation network is performed based on the gear pattern. To perform the contouring, the gear is scanned by a laser line. This process involves image processing of a laser line pattern. The network performs the gear modeling without measurements on the optical setup. In this manner, errors of the measurement are not added to the computational model. Thus, the setup performance and accuracy are improved. To describe the accuracy a mean square of error is calculated using data provided by the network and data given by a contact method. This technique is tested with real gears and its experimental results are presented.
