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