Machining of CoDiCo fiber reinforced thermoset and thermoplastics

Advisors: Schulze (wbk), Tutunea-Fatan (UWO)

In the second generation, the investigation of the machinability will be continued for CoDiCoFRTS, since the complexity of this research field is vast. In the second part of the second generation machining of FRTP will be investigated. Due to the ductility and the low melting point of thermoplastic material, new process strategies have to be developed. One possible way to solve these problems, could be the use of cryogenic cooling, which embrittles the polymer thereby enabling a more favorable chipping mechanism. Furthermore, the part and tool gets cooled down, which prevents the partial melting during the machining process. Another possibility is the application of alternative machining processes, which avoid temperature rise by having different kinematics. 3rd Gen. (“Simulation-based optimization of machining of CoDiCoFRP”) The third generation will continue the developments made in the second generation. The processes under investigation in the second generation, will be developed further to be applicable for the industrial scale production of parts. This might include designing tools as well as simulation of the machining process and machine kinematics. For a more productive machining process, robotic kinematics could be considered. Since the machining of complex 3D parts will have an increasing share of the machined specimens, flexible clamping systems will also be taken into account and developed accordingly.
