Hoffmann Group Taels to maktyau better 47 Conversion for TPC applications Even conventional solid carbide end mills can be used for the trochoidal milling strategy. To do this, simply convert the fz value (feed rate per tooth) to the TPC hnrnl„ value (average chip thickness). Example (slot drill 202977 for hard machining): 1. Take the fz value (for side milling) for the slot drill from the table. 0f8 Dc £ 202976 e 202977 f i L 202976 I 202977 i L4 202977 D4 202977 f i K 202976 i 202977 Carbide roughing slot drill MTC H MTC/TPC mm TiAIN mm 4 8 11 18 3.8 54 57 5 9 13 18 4.7 54 57 6 10 13 20 5.5 54 57 mm 6 6 6 < 0 HRC <60 HRC mm 0.05 0.008 0.008 0.1 0.01 0.01 0.1 0.01 0.01 2.
