Precision Milling of Hardened Steel with CBN Tools

Abstract:

The paper presents research of milling tool inclination angle δ influence (in relation to the cutting surface) on the free surface roughness. Rotational tools with curved cutting edges (ball nose cutter) performed translation movements on the spherical surface of hardened steel work piece (hardness of 50, 62 and 65 HRC). Milling tool with diameter d=1 mm was made of CBN. Roughness measurements were performed in different places of the milling surface with the Taylor Hobson profilometer.
