Trouble shooting carbide milling Vibrations Poor surface finish Improve the stability of cutter and workpiece. Change cutter positioning. Minimize tool overhang. Reduce the cutting speed. Increase the feed rate. Reduce the depth of cut. Select a different insert geometriy, see page Insert geometry Use Steadyline antivibration bar Improve the stability of cutter and workpiece. Minimize tool overhang. Reduce the feed rate. Incease the cutting speed Use coolant. Use wiper inserts. Keep feed/rev value within wiper width Use Steadyline antivibration bar Tool life problems Rapid flank wear Rapid notch wear Chipping Reduce the cutting speed. Increase the feed rate. Climb milling. Reduce the cutting speed. Increase the feed rate. Increase the depth of cut. Climb milling. Change cutter positioning Increase the cutting speed. reduce the feed rate. Conventional milling. Improve chip evacuation. Change cutter positioning. Minimize tool overhang. Improve stability. Comb cracks Built-up edge (BUE) Reduce the cutting speed. Reduce the feed rate. No coolant Change cutter positioning. Increase the cutting speed. Increase the feed rate No coolant. Climb milling. Change cutter positioning 731
