STL format is today commonly used file format for visualisation, simulation and calculations of many kinds. Thanks to increase of computing power of todays´ PCs, this format is well known also in the CAD/CAM area. As for reverse engineering, this format is used as a ...

The paper is devoted by evaluation influence of production and thin film on quality and durability of cutting edge on hobbing cutters and pull broachers, that are produced by PILSEN TOOLS. Based on comparing characteristics of film from different producers and technologies, their&...

Predkladaný článok má experimentálny charakter. Pojednáva o stave drsnosti povrchu pri frézovaní materiálu s rozdielnou tvrdosťou. Stav povrchu bol sledovaný hodnotami Ra a Rz po frézovaní jednozubovou a viaczubovou frézov. Pri sledovaní stavu povrchu boli dosiahnuté namerané hodnoty drsnosti porovnáv...

CNC milling machines are as common today as a mobile phone in teenagers´ hand. Multi-axes metal-cutting machines are not far from similar fate. There is no obstacle on their path to become a common used tool – not even the high price. Everyone who can calculate the&#...

Ceramic cutting tools availability during interrupted machining was solution at this article, in the concrete ceramic DISAL D320 from Czech producer Saint Gobain Advanced Ceramic Turnov. Experiments were provided at special fixture – interrupted cut simulator. This fixture was constructed at ...

Carbon and glass fibre reinforced polymers are applied to an increasing degree in the major industries, like automotive and aircraft industry. These materials are usually machined using cutting tools. Twist drills for instance are used for inserting drill holes to join comp...

Deep hole drilling methods such as BTA-deep hole drilling are machining processes to produce boreholes with high length to diameter ratio as well as boreholes with high quality. Nevertheless, if prism-shaped workpieces or workpieces with eccentrically placed boreholes have to be machined...

Elimination of exploitation of procedural liquids that burden environment is one of actual tendency in cutting technology. Some experiments in this context were realised on Department of Machining and Assembly in Technical University of Liberec. Grinding without supply of procedural liquid a...

Geometrical surface structure is system of geometrical surface components which is mainly determined by shape, dimension and theirs deviations. These parameters are frequently resulting of working parameters or wear. Very study parameter of rotary component is roundness. The paper discusses the&#...
