Abstract In this paper, the wear of the conventional rectangular cutter head and the three-layer sandwich cutter head are analyzed in detail in the case of a large number of observations on the wear of the sawing cutter head in actual production. Three different shapes of the sandwich cutter are pointed out, and the influencing factors are discussed. The ordinary rectangular cutter head is used as the wear model, and the end face is considered to be elliptical due to wear, so that the wear velocity distribution formula of the end face of the cutter head during initial operation is derived, and the "strong wear portion is matched with the high wear resistance layer. The method of designing the internal structure of the sandwich cutter head and the multilayer cutter head.
