The analysis of accuracy of machined surfaces and surfaces roughness after 3axis and 5axis milling

This article concentrates on the assessment of a 3D shape of parts of components. The 3D shape is divided into three distinctive shapes: a spherical canopy, a pyramid, and a concave transition between these shapes. Create these shape surfaces, various strategies of 3axis and 5axis milling are used. These strategies are described and then compared on a model in CAM MasterCAM software. The surface of the component is further measured with a roughness measuring device. The accuracy of the surface of the component is measured using a 3D measurement centre and then compared between surfaces with a different machining strategy. The last criterion for comparing machining strategies is to compare machining surfaces with a drawn tool over a pushed tool. Lastly, the best machining strategy is selected for the most suited surface of the component. © 2018. Published by Manufacturing Technology.
