Organization of the tooling service mainly depends on the profile of the production plant. In large enterprises the important problem are both the organization of the tooling service and tool flow. For realized manufacturing process besides the flow tools process the correct selection of the cutting parameters is also important. In mechanical working operations, an important issue is to select the tools that will limit the size of the designated production pace and provide for them the required tool life. The aim of this study is to analyze the wear of cutting tools on the production line of bodies at the metallurgical plant. Cutting tools used for this line are mainly drills, milling cutters and multi-blade inserts for face milling cutters and end mills. The paper presents the analysis of tool wear on the machining line of brackets. It has been shown that the cost of tool wear is about 4.2% of production costs of parts. It corresponds to the costs reported in the literature. The proper selection of the machining parameters makes it possible to reduce these costs.

In this essay an attempt is made to assess the waste of nine 34 years old reinforced concrete columnar structures. The method of waste assessment of reinforced concrete structures was proposed. On the basis on proper inspection the method of repair of analysed structures was shown. The problems of maintenance of reinforced concrete structures were discussed as well.
