Ceramic Cutting Tool Test with Interputted Cut Simulator

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 Department of Machining and Assembly. Monitored parameter was number of shocks to totally destruction. The goals of tests were contribute to bigger using of these cutting materials at machining, especially at interrupted machining

Influence of High Speed Parameters on the Quality of Machined Surface

The contribution is dealing with the influence of high speed parameters on the quality of machined surface. In general the principle of high speed cutting lies in achieving faster machine times with concurrent increase in accuracy and quality of the machined areas in largely irregular, mathematically hard to define shapes. High speed machining is a highly effective method of machining with the following goals: increasing of machining productivity, increasing of quality of the machined surface, improving of machining economy, improving of ecological aspects of machining. This article is based on an experiment performed by the Department of Machining and Assembly of the Faculty of Mechanical Engineering of VŠBTechnical University of Ostrava
