(Ra) decreases by 73.77% | (Fa) decreases by 65.8% (Fr) decreases by 77.2% (Ft) decreases by 63.1% |
| Increasing the feed rate (f) from 0.1 to 0.2 mm/rev |
(Ra) increases by 15.5% | (Fa) increases by 81.9% (Fr) increases by 73.4% (Ft) increases by 68.7% |
| Increasing the depth of cut (ap) from 0.2 to 0.3 mm |
(Ra) increases by 44.7% | (Fa) increases by 74.2% (Fr) increases by 24.3% (Ft) increases by 21.7% |
| Increasing the insert radius (rƐ) from 0.4 to 0.8 mm Vc = 34 m/mn f = 0.08 mm/rev ap = 0.15 mm |
(Ra) decreases From 1.02 to 0.82 |
(Fa) increases from 11.43 to 13.74 N |
