A Research on The Evaluation of Performances After Re-Sharpening of The End Mills

In this study, the performances of end mills used widely in machining were investigated case their reuse by sharpening. For purpose, at CNC vertical center, slot milling processes carried out with HSS (used once) on AISI 1050 manufacturing steel having two different diameters and carbide (again D2 (2080) cold work tool diameters. Machining experiments made using four cutting speeds, feed depths. These mills, afterwards, re-sharpened considering original geometry repeated same conditions evaluated comparison new tool. general, wear amounts sharpened tools observed to be higher respect tools. tools, no adverse effect sharpening process was performance. especially from point surface quality for small diameter there is re-sharpening can recommended condition observing parallel increase diameter.
