Abstract
The stream finishing process represents an established and efficient production process for surface smoothing and edge rounding. In addition to the targeted setting of a defined surface topography the process features a high potential for mechanical surface modification that has not been realized yet. In this work the stream finishing process is carried out on normalised AISI4140 plane specimen with the aim of efficiently determining optimal processing time for surface modification (micro hardness, residual stresses, surface topography). In this context, the suitability of the Almen system [1] as an efficient method for characterizing change in residual stress during stream finishing is investigated.
