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...

In this paper the influence of different machining parameters on the surface roughness, cutting force and material removal rate during turning process using MQLC (minimum quantity lubrication and cooling) system was investigated. The experimental plan was defined using Taguchi’s method. Orthogonal array L9 (34) was selected for four input par...

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...
