Periodic Reporting for period 1 - MoMenT (Modelling and Measurement of Thermal Phenomena in Metal Cutting)
Período documentado: 2018-07-01 hasta 2020-06-30
This research project aims to develop a reliable instrument for quantitative evaluation of thermal phenomena for cutting tool products and R&D solutions.
The overall objectives:
1 Complete the functionality of the industry-oriented framework model;
2 Complement the framework model with a set of satellite modules for solution of industrially relevant applications in tooling;
3 Utilize the developed approach and experimental solutions around it for credible monitoring of cutting temperature and thus convert R&D effort into a product - Smart Sensors.
Conclusions of the action.
To achieve the planned overall objectives, the following specific scientific objectives were completed:
Created an add-on module of adequate thermal resistance (TR) in realistic tool assemblies and thus the framework model was closed (TR).
Created satellite module for measurement of temperature and its distribution in a cutting tool (SM1).
Created satellite module for quantitative measure of effects of different tool coatings and tool materials (SM2).
Created satellite module for monitoring of momentary cutting temperature through Infrared camera (SM3).
Created satellite module for quantification of effects of different cooling strategies (SM4).

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.

May 2020, June 2020, Result summary and patent preparation because the method was considered as patentable.

Seco Tools specifically chose the four particular modules (SM1-SM4) because it considers them economically most attractive. SM1 and SM3 can be commercialized to SECO Tools customers, while SM2 and SM4 will contribute to “internal know-how” and hence provides a competitive edge for the company. The solutions will be limited to turning
operations because stationary tooling gives increased ease and reliability to measure input data for the inverse problem. Within turning, the main application areas addressed are machining of difficult-to-cut materials. Seco Tools has a global priority in developing machining oslutions for ISO S (Ti-, Ni-alloys) and ISO M (Stainless steels) material groups, as the temperature-driven damage and failure of tooling are most commonly observed there.
To further exploit the scientific results that have been obtained through this funded fellowship (through Marie-Curie Actions), Seco Tools has now decided to employ the awardee of this fellowship (Dr. Vyacheslav Kryzhanivskyy) who has now started his position as a R&D specialist as of 01st July 2020.
The results that bear the potential for the commercialization and IP protection will be continuously collected and evaluated by the participants (at SECO Tools and Lund University where applicable). Together with Seco Tools staff, I will work on the protection of own developments and generated ideas by filing patents whenever possible.
