Abstract: In order to evaluate the cutting performance of the longitudinal cutting heads with various numbers of helical lines, on the premise of the cutting heads possessing the same dimensions, the same total number of picks, the same type of the pick and toothholder, the models of the cutting head with two helical lines (2LC typed) and three helical lines (3LC typed) were established After simulation by programming, the models were compared from chip size, loading size and the number of effective picks operating simultaneously The results showed that the average chip area of the 3LC typed cutting head was 052% larger than that of the 2LC typed, and the rock falling from the picks on the section of spherical surface of the 2LC typed cutting head was not satisfied, being easy to produce dust Compared with the 2LC typed cutting head, the 3LC typed cutting head possessed the smaller load coefficient of variation, and the pick's effective coefficient of variation was less also, which led to better load stability The research offered some theoretical basis for optimization design of the pick arrangement
