STC C - 2013 Annual report

In 2013, the Scientific Technical Committee Cutting STC “C” continued its dedicated work of the past. The STC work continued under the current officers: Chair: M. Davies, Vice Chair: R. M’Saoubi, Secretary, D. Biermann. The group held two meetings in 2013: on January 24th in Paris, France and on August 23rd, in Copenhagen, Denmark.

During 2013, some of the topics discussed in STC ”C” were machining of aerospace materials (CFRP, Nickel based and Ti based alloys), coatings, deep hole drilling, micro-machining, surface integrity, adhesive fixture, new sensors, cutting fluids, modeling and simulation regarding phase transformations and energy requirements.

Presentation of cooperative work in STC C was given by K.-D. Bouzakis. He presented a draft of a paper to be submitted in CIRP Journal of Manufacturing Science and Technology (K.-D. Bouzakis, N. Michailidis, G. Kordaris, E. Bouzakis, S. Kombogiannis): “Cutting edge preparation of coated tools”. A total of about 20 participants took part in this cooperative work. PVD coated inserts with various edge preparations were tested in milling operation for a range of work materials (42CrMo4, AISI304L, IN718, Ti6Al4V).
