Trouble-shooting

Solutions to common problems

Problem Possible Cause Solution
Poor sizing/difficulty holding tolerance Cleanliness Clean tool holder and spindle mounting faces
Insert mounting (sufficient pullback) Check for pull back on insert
Unit or cartridge rigidity
  • Check that the cartridge or unit is correctly fitted and seating properly
  • Check that the cartridge or unit are being operated within the recommended range with the correct radius insert
Material variance
Roughing setup – depth of cut
Core shift
Datum offsets
Coolant supply
Swarf nesting Insert geometry (chip breakers)
Feed rate too low Increase feed rate
Chatter/vibration Cleanliness
Length diameter ratio
Poor finish Feed rate too high Decrease feed rate
Cleanliness
Chip evacuation
Balancing
Ovality Fixture clamping
Balancing
Roughing tool setup
Excessive insert wear Excessive flank wear
  • Reduce cutting speed
  • Review and select a more resistant grade of insert
Crater wear Select insert with more positive geometry
Plastic deformation
Built up edge
Broken inserts Excessive load
  • Check for program errors (rapids)
  • Reduce depth of cut
Grade too brittle
Geometry too weak
Insert too small
Feed too high
Speed too high
