Curing

The hardening process has to follow a defined temperature program (examples given in Fig. 3.8). Several chemical processes happen during curing depending on the actual temperature [COLL88, GARZ00, p. 331]: • 70-80 °C: The resin bond starts to flow and to transform into a fused mass. Water in the phenol resin evaporates and the resin […]

Porosity

Pores are necessary for the transport of cooling lubricant to and chips away from the cutting point. They become more critical for high material removal rates and high-speed grinding processes to get enough cooling lubricant into the grindinggap. Grinding wheels with discontinuous cutting faces have similar effects as highly porous wheels [BORK92, p. 36]. Porosity […]

Axiomatic Grinding Process Model

Section 7.1 described different methods for evaluating sustainability and Sect. 7.2 derived the life cycle inventory for grinding to implement these methods. Data for the analysis is either measured empirically, estimated or obtained from databases. Ideally, fundamental process knowledge would allow calculating all input and output streams from physical and analytical models. The following study […]

Life Cycle and Sustainability of Abrasive Tools

This thesis was written mainly during my time as postdoc researcher at the Werkzeugmaschinenlabor (WZL) at the RWTH Aachen University, and at the Laboratory for Manufacturing and Sustainability (LMAS) at the University of California Berkeley. The research on the life cycle engineering of abrasive tools was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) […]
