| Popis: | The paper aims to process the concave cylindrical surfaces. This proposes a comparison between the processing of concave cylindrical surfaces with toroidal milling and the processing of concave cylindrical surfaces with spherical milling. The variable process parameters are the cutting speed, the feed per tooth and the inclination angle between the tool axis and the normal to surface. After processing, the surface with the best roughness is tracked according to the regimes and the tool used. A number of 27 concave cylindrical surfaces machined with toroidal milling cutter and 27 concave cylindrical surfaces machined with spherical head milling are machined. The aim is to measure the arithmetic roughness Ra and the total roughness Rt, these being measured parallel and perpendicular to the direction of advance. In order to confirm the correctness of the measured values, microscopic images with the best surfaces will be captured. |
