General Turning /Allgemeine Drehbearbeitung, ISO Kennzeichnung Turning · Drehen Application information . Anwendungsinformation Tool No. wear Situation Reason Countermeasures type Grade is too soft Select grade with higher wear Poor surface quality resistance Cutting speed is too high. A 1+2 Flank wear and inconsistent Reduce cutting speed measurement. Increase Flank angle is too small. Increase flank angle. in cutting force. Feed rate is too low Increase feed rate Grade is too soft. Select grade with higher wear Crater wear Bad surface and resistance 3 Cutting speed is too high. chip control Reduce cutting speed Feed rate is too high. Reduce feed rate Grade is too hard. Allgemeine Drehbearbeitung Feed rate is too high. Select grade with higher Tool life not stable Cutting edge strength not toughness 4 Chipping Sudden breakage of Reduce feed rate cutting edge strong enough Change honing of cutting edge The rigidity of holder in Use holder with bigger shank size insuffiecient (vibration) General Turning Grade is too hard. Feed rate is too high. Select grade with higher toughness Cutting force increasing Cutting edge strength not 5 Fracturing Surface roughness and Reduce feed rate measure becomes bad strong enough Change honing of cutting edge The rigidity of holder in Use holder with bigger shank size insufficient Grade is too soft. Inconsistent measure Cutting speed is too high. Grade with high wear resistance. Plastic meet. Reduce cutting speed 6 deformation Depth of cut and feed rate too Damage to the cutting Decrease depth of cut and feed rate. edge high Grade with high thermal conductivity. Cutting temperature is high Poor surface quality Cutting speed is low. Cutting edge not sharp Increase cutting speed and inconsistent 7 Welding measurement. Increase Increase rake angle. enough Select grade with lower affinity in cutting force. Grade not suitable Break due to thermal Expansion or Thermal Use dry cutting 8 variation effect often Cracks caused when cutting is shrinkage due to cutting heat Select grade with higher Grade is too hard. toughness interrupted. Unstable cutting condition (uncut surface,chilled parts, machining hardened layer) Grade with high wear resistance. 9 Notch wear Burr increase of Increase rake angle to improve Cutting force information Friction caused by jagged sharpness shape chips. Decrease cutting speed Feed rate and cutting speed too high Mostly happens during Cutting edge welding and Increase rake angle to improve 10 Flaking machining of high hard adhesion. sharpness materials or vibration Use chip breaker with wider chip Bad chip removing pocket 3 6 7 89 9 4 10 5 2 1 A 282
