PROBLEM |
CAUSE |
SOLUTION |
|
|
|
| Chipping |
Feed rate too high |
Reduce feed rate |
|
Chattering |
Reduce RPM |
|
Loose tool |
Remove & clean, tighten collet |
|
Workpiece rigidity |
Tighten workpiece holding method |
|
Poor tool rigidity |
Shorten LOC, place shank further up toolholder |
|
Low cutting speed |
Increase RPM |
| |
|
|
| Wear |
High cutting speed |
Reduce RPM |
|
Hard material |
Use coated tool |
|
Low feed rate |
Increase feed rate |
|
Poor chip evacuation |
Reposition coolant lines, use vacuum |
|
Improper cutting angle |
Adjust cutting angle |
|
Feed rate too high |
Reduce feed rate |
| |
|
|
| Breakage |
Poor tool rigidity |
Shorten LOC, place shank further up toolholder |
|
Tool wear |
Regrind/replace sooner |
|
Depth of cut too large |
Reduce depth of cut |
|
Feed & speed too fast |
Reduce feed rate |
|
Relief angle too high |
Use lower relief angle |
|
Depth of cut too large |
Reduce depth of cut |
| |
|
|
| Chattering |
Poor tool rigidity |
Shorten LOC, place shank further up toolholder |
|
Poor toolholder rigidity |
Replace with shorter/more rigid holder |
|
Poor spindle rigidity |
Use larger spindle or different tool |
|
Poor workpiece rigidity |
Refixture workpiece holding method |
|
Improper cutting angle |
Regrind with proper clearance angle |
| |
|
|
| Short Tool Life |
Hard material |
Use coated tool |
|
Cutting friction high |
Regind/replace sooner or use coated tool |
|
Feed rate too high |
Reduce feed rate or increase speed |
| |
|
|
| Chip Packing |
Low cutting speed |
Increase RPM or reduce feed rate |
|
Insufficient chip room |
Use tool with less flutes, increase helix |
|
Insufficient coolant |
Use additional coolant lines |
|
Feed rate too high |
Reduce feed rate |
|
Low cutting speed |
Increase RPM |
| |
|
|
| Poor Surface Finish |
Tool wear |
Regrind/replace sooner |
|
Edge bulid up |
Increase RPM |
|
Depth of cut too large |
Reduce depth of cut |
|
Recutting chips |
Increase coolant volume |
| |
|
|
| Burring |
Feed rate too high |
Reduce feed rate |
|
Depth of cut too large |
Reduce depth of cut |
|
Tool wear |
Rerind/replace sooner |
|
Improper helix angle |
Change to proper angle |
