Studying the influence of the machining process on the geometrical defects of the standardized S-shape test part

In 2020, an S-shape part was proposed as a 5-axis reception test in the new version of ISO 10791–7:2020. This enables testing machine-tool behavior that involves high variation tool axis orientation. is formed fillet which machined flank milling with endmill Ø20 mm. Any defects are influenced by accuracy CAD model, CAM path computation, measurement uncertainty free-formed surface coordinate machine (CMM), and geometric behavior. article aims to quantify influence all these steps on final parts. The conclusion our work based analytical numerical study experimental analysis. Finally, we propose identification process for architecture geometrical pertaining part.
