PT Journal AU Hanzl, P Zetkova, I TI Benefits of a New Approach to Designing Milling Cutter Using Metal Additive Manufacturing SO Manufacturing Technology Journal PY 2019 BP 385 EP 390 VL 19 IS 3 DI 10.21062/ujep/301.2019/a/1213-2489/MT/19/3/385 DE Milling tool; Topological optimization; Direct Melting Laser Sintering; Metal Additive Manufacturing AB Topological optimization is the process of reducing part weight while respecting strength requirements. This paper focuses on its possible positive consequences for the machining process. The main aim is to carry out a survey to obtain knowledge that will be applied during the topological optimization of a milling tool. According to all the indicators, the efficient implementation of lattice structures into the milling concept has the potential to achieve a high level of innovation, since the functional weight reduction of the tool allows for higher dynamics of the cutting process. The modified rigidity of the milling cutter and vibration absorption can extend the life of the cutting edge, and such a milling tool would provide a competitive advantage on the tool market. ER
