Comparative wear analysis of modified cutters during processing of milling of selected wood-based materials. This study presents comparative investigations of durability of cutters covered with different variants of antiwear coatings. The impact of hard coatings spread on faces of cutters on the wear of cutting edges during the process of milling of chipboards and MDFs was investigated. Every time, the wear of the cutting edge caused by milling chipboards and MDFs was determined in the area of the same cutter utilising the entire length of the main milling edge which guaranteed the same characteristics of the applied coating. The edge wear surface area was measured using, for this purpose, a surface analyser. It was established that milling chip boards and MDFs of similar mean density using cutters made from high-speed steel covered with antiwear coatings of different characteristics caused, for each of the examined cutting edges, at least over 50 times greater wear during chipboard milling. The character of the obtained wear curves makes it possible to assume that the applied milling method will allow initial assessment of edge durability, especially in the case of MDF and will make it possible, on this basis, to plan the timetable of investigations.
