• Increased tool wear• Select a more wear resistant grade • Use an insert with a larger rake angle • Select a freer-cutting chipbreaker type • Use an insert with a larger nose radius • Use a more lightly honed insert • Use an insert of closer tolerance (from M class to G class)• Select a proper feed • Decrease the cutting speed • Use a cutting fl uid
rface roughness• Edge chipping• Use a tougher grade • Select a chipbreaker with strong cutting edges • Use a largely honed insert • Increase the side cutting edge angle • Use a larger shank size• Decrease the depth of cut • Decrease the feed • Use a more rigid machine • Improve the holding rigidity of the tool and workpiece • Shorten the overhang of the toolholder • Improve the machine looseness
Deteriorated su• Chip welding • Built-up-edge• Select a grade with less affi nity with the Workpiece material • Use an insert with a larger rake angle • Select a freer-cutting chipbreaker type • Use a more lightly honed insert • Use an insert of closer tolerance (from M class to G class)• Increase the cutting speed • Increase the feed • Use a water-insoluble cutting fl uid • Use a cutting fl uid
• Vibration and chatter• Use a tougher grade • Use an insert with a larger rake angle • Select a freer-cutting chipbreaker type • Use an insert with a smaller nose radius • Decrease the side cutting edge angle • Use a more lightly honed insert • Use a larger shank size• Use a proper cutting speed • Decrease the feed • Decrease the depth of cut • Improve the holding rigidity of the tool and workpiece • Shorten the overhang of the toolholder • Improve the machine looseness
ted nal cy• Improper insert accuracy• Use an insert of closer tolerance (from M class to G class)
Deteriora dimensio accura• Incomplete engagement of tool and workpiece• Use an insert with a larger rake angle • Select a freer-cutting chipbreaker type • Use an insert with a smaller nose radius • Use a more lightly honed insert• Improve the holding rigidity of the tool and workpiece • Shorten the overhang of the toolholder • Improve the machine looseness
ce• Unsuitable cutting speed• Decrease the cutting speed • Increase the feed • Use a cutting fl uid
