The quality of regeneration using polymer masses of splineways was assessed based on the analysis of the properties of polymer compounds used as regeneration masses. Three different polymer compounds consisting of epoxy resin and curing agents were used to the tests. Each of the cured polymer compounds was tested for surface roughness - (i) the mass located in the filled splineways and compressive test - (ii) a cured cylindrical sample of the polymer mass. After the curing process, the regenerative masses located in the splineways (i) were also subjected to finishing processing by milling. Additionally, the compressive strength was determined for the polymer masses, taking into account three seasoning conditions: (i) 1 week at a temperature of 27 ± 2 ℃ and humidity of 20 ± 1%, (ii) 4 weeks at a temperature of 80 ℃ and a humidity of 95% and (iii) 6 weeks at 80 ℃ and 95% humidity. Surface roughness parameters were measured using a contact profilometer. Samples of cured polymer mass were subjected to strength tests on a Zwick/Roell 150 testing machine, in accordance with the ISO 604 standard, determining compressive strength. Based on the results, it was noticed that the type of regenerative mass affects the quality of the regenerated surface and compressive strength, and the influence of seasoning conditions on this strength is also significant, depending on the type of polymer mass.
