New observations on built-up edge structures for improving machining performance during the cutting of superduplex stainless steel

This work features a comprehensive investigation of built-up edge (BUE) formation during machining of superduplex stainless steel (SDSS), grade UNS S32750. To visually investigate BUE formation during the machining test, a detailed examination of BUE structures obtained at different cutting speeds was performed. The BUE geometries were determined by scanning electron microscope (SEM) and 3D white light interferometry. In addition, various BUE …
