A study was conducted to test the wear on a cutting edge when machining melamine coated particle boards. This study utilized particle boards made by 3 different producers. In each of the 3 cases there was a high degree of dissimilarity in the wear of the cutting edge after processing. The following factors were found to have a profound effect on tool wear: sand content, weighted average sand, cutting path, cutting speed and the sharpness angle. No impact on tool wear was found with regard to resrn and filler content in melamine film and micro-hardness of melamine film.
