The tool wear evaluation has a very strong impact on the product quality as well as efficiency of themanufacturing process. This paper presents the further development of an innovative and reliable direct measuringprocedure for measuring spatial cutting tool wear. The influence of the orientation of measurement head accordingto the measurand was examined. Based on the analysis of measurements accuracy and the amount of capturedreliable data, the optimal setup of the measuring system was defined. Further a special clamping system wasdesigned to mount the measurement device on the machine tool.To test the measurement system tool life experiment wereperformed, where cutting tool wear was measured directlyon machine tool. The results showed that novel tool wear diagnostic represent objective estimation, performed on amachine tool that provides higher productivity and quality of the machining process.

The development of cutting simulation still requires an improvement in the understanding of the frictional phenomena at the tool-work material interface. This paper introduces a method for a fast identification of friction and heat partition models, based on a special tribometer able to simulate wide ranges of contact pressures and sliding velocities, similar to those occurring along the tool-work material interface in cutting. The method is applied for a wide spectrum of work materials and lubrication conditions. Combined with an analytical post-treatment, this set-up provides a modelling of the frictional behaviour that may improve significantly thermal aspects in cutting simulations.

The aim of this paper is to present the benefits if we use two manufacturing processes to make one product. In our case we use subtractive and additive manufacturing technology. Subtractive process is the high speed cutting and additive process is the selective laser melting. We want to combine these two technologies in hybrid manufacturing. Hybrid manufacturing combine benefits of both processes and eliminate limitations. On the end of this paper is presented developed computer software which analyse a geometric design of product and determine which part of product will be done with specific technology.
