Depth-of-cut notch
|
1. Avoid built-up edge.
2. Increase the tool lead
angle.
3. Maintain speed and
decrease feed rate simultaneously.
4. Ensure proper insert
seating.
5. Increase coolant concentration.
6. Depth of cut should be
greater than the work-hardened
Layer resulting from the
previous cut (>0,12mm/.005").cnc
9. Use strongest insert
shape possible.
10. Program a ramp to vary
depth of cut.
