Infeed Method Infeed Method Infeed method Alternating flank infeed Features Most simple and usual method Suitable for the relatively small pitch threads of easily-machinable material Chip contact length on right and left is longer causing chattering with increased load on the nose end. When the half included angle is not symmetrical to right and left infeeding in the direction of 1 2 of the included angle will ensure equal machining with right and left cutting edges. Suitable for the large pitch thread or easy to tear materials. Effectively prevents chattering. Chips are discharged in one direction only. Satisfactory chip handling. Edge on the right (with zero infeed) tends to be worn heavily. Suitable for the large pitch thread or easy to tear materials. Effectively prevents chattering. Chips are discharged in one direction only. Satisfactory chip handling. Edge on the right performs a certain cutting. Wear of this edge can thus be suppressed. Suitable for the large pitch thread or easy to tear material. Effectively prevents chattering. Chips are discharged alternately in right and left directions resulting possibly in entanglement. Right and left edges are used alternately ensuring uniform wear and extending tool life. TAC Threading Tools
