July 2018, Data management plan preparation and integration into Seco Tools’ environment.
August 2018, Purchase of licenses for Optimisation toolbox (MATLAB), Livelink to MATLAB (Comsol Multiphysics), Heat transfer module (Comsol Multiphysics); Design and manufacturing of samples for thermal resistance experiments on LFA machine (This is needed to complete Satellite module “Thermal resistance”, performed within WP1 of the work plan).
September - October 2018, Design and manufacturing of thermocouples equipped tool holders for longitudinal turning for TPUN and TNMA geometries (Satellite module “Temperature distribution” (SM1), WP1 of the work plan).
November - December 2018, Experiment plan implementation. This plan included two types of insert geometries (TNMA, TPUN) as well as two sorts of inserts with different percentage of cobalt.
January - February 2019, Establishing of FE models for manufactured thermocouples equipped tools. Testing and sensitivity analysis. (Action performed within WP2). Tool temperature distribution modelling on the base of experimental data previously collected. Training on operation with IR camera available at Seco Tools. Machine Learning course attending (Stanford online).
March 2019, Experiments preparation on Cooling Strategies (SM 4, WP2 of Work plan) in Lund University (purchase of nozzles for cooling media, experimental setup design).
April 2019 - May 2019, Lund University secondment. This activity covers two points: (i) Operation with LFA apparatus, (ii) Cooling strategies investigations. The first one is needed to create reliable database with temperature dependent properties for different sorts of cemented carbide and thermal resistances existing in tool assemblies. The second one is for implementation of the Satellite module “Cooling investigations” (WP2). The satellite modules “Thermal resistance” (WP1), “Temperature distribution” (WP1) and “Cooling investigations” (WP2) were completed.
June 2019, Scientific paper preparation and submission to International Journal of Machine Tool and Manufacture.
July 2019, Vacation
August 2019, Revision of the paper following the reviewers’ comments. Because colleagues from Lund University were unable to manufacture a tool with printed thermocouples as was planned by September 2019, the plan was corrected. The correction of the plan consisted of registering temperatures in the cutting zone with the help of a high-speed infrared camera and a specially adapted toolholder instead of printed thermocouples.
