Drilling >120o) 1. Drilling in solid material (Top lip twist drill, point angle = I) The gripping force required is determined by the Typee of work to be performed. The calculation described below applies to freely chucked work, i. e. workpieces which are not axially seated against the jaws. In this situation the components FsBo (cutting force) and Fvax (feeding force) acting on the workpiece give the resultant FR to determine the gripping force. The cutting force FsBo can be calculated from FsBo = s · t · kc (4) Power-operated clamping devices where: s = feed, mm/rev. drill diameter t = depth of cut, mm = 2 kc = specific cutting force kN/mm2 Feeding force Fvax Table 6 Feeding force for drilling in solid material using a twist drill The feeding force Fvax bears a given relationship to thecutting force and can be directly obtained from Table 6. 40 25 m) 16 er mt 10 ia ill d d1 (m Dr 6,3 4,0 2,5 1,6 0,80 1,25 2,0 3,15 5,0 8,0 12,5 20 31,5 50 80 Cutting force FsBO [kN] www.eshop.roehm.biz 6209
