Factores de fatiga en operadores de maquinaria semiautomatizada en Mexico
In this study the Swedish Occupational Fatigue InventorySpanish version (SOFI-S) was applied in order to identify the symptoms of fatigue between Advances Manufacturing Technology (AMT) operators in Mexico. A total of 121 Computerized Numeric Control (CNC) lathe operators were surveyed in a manufacturer of Constant Velocity (CV) joints located in Celaya, Guanajuato in central Mexico. Typical tasks performed by operators included loading, unloading and machine programming. Results show that the dimension “lack of energy” obtained the highest score of fatigue, while the “lack of motivation” obtained the lowest score of fatigue.
