Beeinflussbarkeit der Bauteilgestalt durch Prozessstellgrößen beim Außenlängsdrehen von AlSi9Cu3 ‐ GJS400 Parallelverbunden

Abstract

To guarantee excellent work piece quality for the machining of compound materials characteristic interactions between the components have to be considered in the process design. Especially by parallel compounds, where the different components are processed in an alternating manner, the machinability of the compound differs considerably from the machinability of each homogeneous component. Depending on the compound partner the surface topography of a component can vary considerably. Rotationally symmetric compound work pieces primary hold radius and transition deviations. In addition to unequal tool and workpiece deflection the radius deviations results from the different topographies in each component. The surface topography and its measurement methods as well as the process parameters and their influence on the process forces have to be considered for a proper process design.
