Sub-zero milling of Ti-6Al-4V—impact of the cutting parameters on the resulting forces, tool wear, and surface quality Open
Due to an excellent ratio of high strength and low density, Ti-6Al-4V is suitable for many industrial applications, especially in the aerospace industry. However, Ti-6Al-4V is also characterized by a very low thermal conductivity and high …
Sub-zero milling of Ti-6Al-4V – Impact of the cutting parameters on the resulting forces, tool wear, and surface quality Open
Due to an excellent ratio of high strength and low density, Ti-6Al-4V is suitable for many industrial applications, especially in the aerospace industry. However, Ti-6Al-4V is also characterized as a hard to-cut material. This is mainly at…
Investigation of the surface integrity when cryogenic milling of Ti-6Al-4V using a sub-zero metalworking fluid Open
In this paper a novel cooling strategy is presented using a sub-zero metalworking fluid when milling Ti-6Al-4V. The metalworking fluid, composed of water and ethane-1,2-diol, was applied to the process at varied supply temperatures. An ana…

Approach for the observation of surface conditions in-process by soft sensors during cryogenic hard turning Open
Even though required for a robust production, direct measurement of the surface condition in-process is a challenge due to technical limitations. A concept for in-process monitoring of surface conditions like hardness or microtopography us…
Fundamental Analysis of the Usability of an Angle-Resolved Scattered Light Sensor for Monitoring Vibratory Finishing Processes Based on Ray Tracing Simulations Open
The angle-resolved scattered light sensor OS500 (made by Optosurf in Ettlingen, Germany) is an optical measuring device that is becoming more and more frequently used inindustrial applications and for the characterization of surfaces in ge…
