EXPERIMENTAL MILLING TESTS OF CUTTING TOOLS AT STAINLESS STEEL
The article is focused on the issue of cutting tools for group of materials M, according to ISO 513, more specifically the area of stainless steel machining. The main objective is to do a practical comparison of selected milling cutters and their inserts at machining of the world's leading manufacturers as Pramet Tools, Mitsubishi, Sandvik and Seco. Experimental testing is focused on functional cutting tests at machining which aim is to test and check significant methods as technique of chip formation during cutting, trajectory of chips leaving, shape and size of chip, tool’s operation in cut (noisiness, vibration) or tool’s operation in cut at various axial depths of cut. Selected tests will be performed on the milling centre Kovosvit MAS MCV 1270 Power, and stainless steel X2CrNiMo1712-2 will be selected as machined material.

Neutron Residual Stress Measurements on Rail Sections for Different Production Conditions
Rail sectioning with subsequent neutron diffraction experiments has been used to assess residual stresses in the rails. In this study we present the results of neutron stress measurements performed at the NIST Center for Neutron Research (NCNR) on rail sections from rails that were produced under various conditions. Specifically, these are air-cooled, air-cooled and roller-straightened, head-hardened and head-hardened and roller-straightened. More significantly, a head-hardened and roller-straightened rail was also studied after service to elucidate evolution of the service-induced residual stresses. In the latter case both a transverse-cut slice and the central region of a 0.53 m long piece were studied. Measurements on this piece are the first in which triaxial stresses have been determined for an intact rail. Neutron strain measurements with 3×3×3 mm3 spatial resolution were successfully employed for transversally cut slices to verify the difference in the stress state depending on the production process. Although examination of slices allows determination of only two-dimensional stresses in the plane of the slice, additional measurements on obliquely-cut slices, which were also carried out, and utilization of FEM gives the possibility of reconstructing the full triaxial stress distribution. Together, these approaches provide a better understanding of rail fabrication and the possibility of improving the durability and safety of rails in the future.Copyright © 2004 by ASME
