|Description: ||The basic quality control activities at the factory are the repetitive analysis and improvements to reduce the variations of quality. Then, it is necessary to determinate the magnitude of the current variations and to identify and analyze the factors that cause them. In quality control the occurrence of flaws is analyzed, researched and prevented, minimizing, then, the damage or, even better, avoiding it to happen. This work analyzed through control charts for variables, the quality of the production of the molders in manufacturing Tauari (Couratari oblongifolia Ducke & R. Knuth) hardwood floors. Twenty-seven samples size one were collected. The variables considered were male’s width, thickness and length, goove thickness and depth, besides the width and thickness of the floor. The results have showed that all the variables were out of the statistic quality control. Among the variables considered, groove thickness presented the greater process variability due to the high shrinkage of the species. As a result, there is a need to the production of a groove thickness bigger than the specification to assure a perfect fit, due to the moisture absorption during the process.|
