RT Journal Article SR Electronic A1 Józwik, Jerzy T1 Analysis of the Effect of Trochoidal Milling on the Surface Roughness of Aluminium Alloys after Milling JF Manufacturing Technology Journal YR 2019 VO 19 IS 5 SP 772 OP 779 DO 10.21062/ujep/370.2019/a/1213-2489/MT/19/5/772 UL https://journalmt.com/artkey/mft-201905-0009.php AB The paper presents the results of the surface morphology of aluminium alloys after milling. The 3D surface roughness parameters Ra, Rz, RSm were examined. Functional relationships between the cutting forces, the torque and the roughness parameters were established. The investigation was carried out with respect to functional characteristics of the surface of aluminium alloys. Two different aluminium alloys: 2024 and 6082, were investigated. Two different milling strategies were employed: milling with a trochoidal tool path and milling with a conventional tool path. Different radial depths of cut were applied in the tests. The percentage of the radial depth of cut was increased every 5 %, from 5 % to 40 %. The results were compared with the conventional machining.
