- ItemHodnocení technologie výroby vnitřních závitů pomocí tváření a obrábění(Technická Univerzita v Liberci, 2009) Hamáček, Richard; Doubek, PavelThe thesis deals with a problem of how the internal thread manufacturing process may influence the mechanical properties of the thread, geometrical precision and economical seriousness. The static tensile test, microhardness test and the metallographic scratch pattern etching for visual comparison of progression of deformation fibres in the material were used to find the influence. The result of experimental measurement is the comparison of hardness along the thread profile in case of forming and cutting technology, comparison of the thread geometry with current economical seriousness of thread manufacturing on Rail F00R.L00.XXX in Bosch Diesel s.r.o company determined.
