The main focus of this paper is to present the TQM practices of 593 companies in Bosnia and Herzegovina. In addition, our results confirm that there are statistically significant differences in TQM practices between firms in a highly competitive and less competitive environment, as well as between firms with and without ISO certificates. TQM practi...

Spare parts are parts of machines, plants and equipment (technical systems) that should be available for replacement when canceling them for various reasons - breaks, abrasion and deformation. By replacing them, the observed technical system places itself in the possibility of functional use. In order to enable the possibility of eliminating failur...

Hydraulic cylinder malfunctions are very common causes for the failure of the operation of the hydraulic system. Most common causes are in cylinder’s seal failure, whereby the error by replacing the seals can be relatively quickly eliminated. In the case of frequent occurrence of the same failure, the problem should be more carefully addresse...

The basic objective of machine structure testing is to reduce the number of structures without satisfactory quality, which are either discarded as scrap or sent for additional machining. The non-destructive testing can detect surface and internal errors in structures, depending on the applied testing method, which enables total quality of the produ...
