STC C - 2015 Annual report

In 2015,the Scientific Technical Committee Cutting STC “C” continued its dedicated work with respect to processes and techniques used to shape components by material removal under the current officers:
Chair: M. Davies, Vice Chair: R. M’Saoubi, Secretary, D. Biermann.

The group held two meetings in 2015: On February 19th in Paris, France and August 28th in Cape Town, South Africa.
During 2015, some of the topics discussed in STC ”C” were temperature measurement, cutting tool optimization for the machining of different materials, PVD coatings, surface integrity, characterization of friction coefficients, cryogenic cooling, modeling and simulation of cutting forces, temperature, residual stress, phase transformations, microstructure and friction.
