摘要： A saw blade (100) has a plurality of teeth (104) with each tooth formed by a beveled leading face (120), a beveled trailing face (122) and a chamfered surface (124) located on the trailing face of each tooth. The trailing (122) and leading (120) faces are beveled in opposite directions in alternate order throughout the saw blade (100) prior to the forming of the chamfered surface (124). The beveled leading face (120) of each tooth intersects the chamfered surface (124) on the trailing face (122) of each tooth to form a curved cutting edge (130) having a negative rake angle. The beveled faces are manufactured by first forming a plurality of rough-formed gullets. The rough-formed gullets are then finished-formed into beveled gullets (110) by a cold-forming operation prior to the grinding of the chamfered surface to form the curved cutting face of the tooth.

摘要： A saw blade (100) has a plurality of teeth (104) with each tooth formed by a beveled gullet (110) forming a trailing face (118), a beveled gullet (110) forming a leading face (116) and a planar surface (122) forming a curved cutting edge (120). The gullets are beveled in opposite directions. The planar surface is generally parallel to the beveled trailing face. The tooth profile provides a saw tooth having a positive rake angle (128) to significantly improve the strength of the tooth. The method of manufacturing of the tooth profile begins by orienting a saw blade blank (160) about three axes and performing a first grinding operation which forms every other tooth gullet and every other planar surface. The partially formed blank is then oriented about two of the three axes in an opposite direction and a second grinding operation is performed. The second grinding operation grinds the remaining gullets and planar surfaces.
