Abstract
The results of measuring the kinematic friction coefficient on polymethyl methacrylate, as well as the results of dimensional analysis in the form of CAD inspection, are presented in this master thesis. The measurement of the konematic friction coefficient was carried out using the "disk-block" friction pair method. Experimental tests were performed for different values of normal load on cylinders made of polymethyl methacrylate that were exposed to increased temperature for their polymerization. Based on the results, it can be concluded that the arithmetic mean value of the kinematic coefficient of friction decreases with increasing force, while for the CAD inspection results, based on the standard deviation, it was established that there are certain deviations present.
