Final report
Abstract:
Due to their mechanical and physical properties, titanium and titanium alloys are among the materials that are difficult to machine. ln a large number of components from the aerospace, chemical industry, medical technology, energy technology and sports equipment technology sectors, internal threads have to be produced. ln general, taps made of high-speed steel (HSS) are used for this purpose. HSS tools are extremely tough and therefore highly resistant to tool breakage, but can only be used at low cutting speeds due to their low heat resistance. This results in long production times and high machining costs. Another problem that occurs particularly in medical technology is the formation of burrs during thread milling in implants made of pure titanium. The removal of burrs, which is usually carried out manually, is very time-consuming and costly.
The aim of the research project was therefore to achieve a significant increase in productivity compared to the current state of the art when producing threads in the titanium alloy TiAI6V4 and a reduction in burr formation when producing threads in pure titanium. To achieve this objective, the research work on TiAI6V4 focused on the development of a significantly more efficient HSS tap compared to the current state of the art. The focus here was on coating development. Furthermore, the influence of the tool micro- and macro-geometry as well as that of substrate pre-treatment and coating post-treatment on the performance of the taps was investigated. The research work in pure titanium focused on the development of a milling strategy to reduce the burrs produced during thread milling.
With the completion of the research project, a new high-performance tool is now available for tapping in TiAI6V4. The HSS tap coated with a DLC coating system has more than doubled the cutting speed and tool life compared to the reference tools. The burrs created during thread milling in titanium implants can be safely removed by circular milling. Manual deburring can be significantly, if not completely, replaced by the developed strategy for the given machining task.
The objective of the research project has been achieved.
