Course content

Students are introduced to where the development of cutting tools is currently heading. It is emphasised to students that cutting tool machining and research is a complex process, the aim of which is to ensure the machining of progressive materials on modern high-performance machine tools, while respecting the requirements for high precision and surface finish. It is reemphasised to the students that the cutting tool, as an important link in the machining unit, is also an important means of intensifying the cutting process. According to the development knowledge and experience of experts in this field, a significant increase in machining productivity can be achieved by using new and high quality cutting tools and by applying higher cutting speeds and feeds. In doing so, these experts foresee an increase in the quality of the machined surface and the functional reliability of the tools, while at the same time reducing the machining time and the overall production cost. These connections to practice are repeatedly presented, explained and discussed to students during the course. Lecture Schedule: 1. Classification of construction materials according to marking, properties and use 2. Possibilities of influencing the structure and properties of structural materials by heat, mechanical and surface treatment 3. Classification of materials for cutting tools according to marking, properties and use 4. Production of cutting tool materials, mechanical and heat treatment 5. Surface treatments and processes. Testing of thin abrasion resistant coatings - I. 6. Surface treatments and processes. Testing of thin abrasion resistant layers - II. 7. Excursion to the company TGS tools-machines-technological services, spol. s r.o., Mýto - lecture by a TGS employee, tour of the company, discussion 8. Special construction materials and their properties in machining 9. Excursion to Ensinger, s.r.o., Dobřany - lecture by Ensinger employee, company tour, discussion 10. Relationship between mechanical, chemical and physical properties and machinability 11. Progressive cutting materials, their applications and limitations 12.
