At the moment, our team consists of seven people, who all contribute to the workgroup day-to-day with their knowledge. Our expertise includes knowledge of engineering, machining, machine components, CAD-CAM technology and standardization. In the recent past the main focus of the group has been related to metal cutting processes. We have examined the wear of cutting tools for milling and turning of various materials and the general effects of the cutting process on the surface of the treated material and its proximity. We have studied the use of different coatings on cutting tools to reduce wear and carried out cutting tests. We have capabilities to measure the forces generated by turning and milling and to analyze the nature of the process. Today, the focus of the workgroup has shifted primarily to digitalisation of production. It involves an integrated approach from design, manufacturing, processing technology and manufacturing precision. In addition, activities in the study of details and mechanisms are developed through X-ray CT scans and material testing.

We are able to carry out rapid prototyping using a variety of 3D printing equipment and 3D scanning capabilities in our lab.
