This master’s thesis addresses the improvement of the performance of a dimensional
inspection device used in a highly automated manufacturing process. The device performs 100% inspection of trailing arms after CNC machining. Dimensions are measured
using various mechanical gauges and measuring devices, as well as a machine vision
system. Initially, the device did not provide measurements that could be reliably used
to determine product conformity. Therefore, an analysis of the initial condition of the
device was carried out, based on which improvement measures were proposed and implemented, resulting in a significant reduction in measurement variation. The study
demonstrated that, with the appropriate approach and regular maintenance, the device
operates reliably and can be effectively used in serial production, where the final status
of products is determined based on its measurement results.
