STC C - 2018 Annual Report

In 2018, 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 leadership of the current officers:
Chair: R. M’Saoubi, Vice Chair: D. Biermann, Secretary: S. Melkote.

The group held two meetings in 2018: on February 22nd in Paris, France and August 24th in Tokyo, Japan.

In 2018, STC “C” continued its cooperative working group efforts launched in 2016 to address specific aspects of friction and material constitutive data used in modelling of machining. Both working groups are well into their proposed efforts and provided updates their progress at the two meetings. The recommendations made by the two working groups are expected to advance our understanding of the advantages and limitations of friction and material constitutive models reported in the literature. In doing so, they will provide guidance to researchers and industry practitioners regarding which models to use for a specific work material. The efforts of the two working groups complements and extends the 2017 STC “C” Keynote paper.

In addition, a number of technical topics were presented and discussed in the two STC “C” meetings. These presentations are listed below. New guidelines for organizing STC meetings put forth by the CIRP Council in 2016 were followed in organizing both meetings of STC “C”.
