Here we report results of a study conducted at an industrial facility located in the central region of Mexico. It is devoted to the
manufacturing of camshafts. We completed an ergonomic assessment on the working circumstances of a production line where
workers interact with CNC lathes. Operating this machinery entails the performance of both physical and cognitive effort,
circumstances that correspond to a process of Advanced Manufacturing Technology (AMT). The study consisted of a visual
inspection of the work areas, video recording both of the site and of the workers in action, analysis of the recordings, and
assessment with the REBA method. The tasks performed by the workers consist of a) handling (loading and unloading to/from
the lathe) the camshaft components, b) visual inspection and test of compliance to the required parameters, c) adjusting the
machinery as required, d) setting the finished pieces in containers. The recorded material allowed identifying 35 separate
operations which were then analysed with the REBA Method. The results were as follows: 3 operations classified as a Very High
Risk Level, 14 classified as High Risk level, 14 classified as Medium Risk Level and 4 operations classified as Low Risk Level.
The body regions most at risk for WRMSD were the trunk, neck, arm and wrist. A series of changes in the workstation layout
and in work procedures have been proposed, in order to ameliorate the ergonomic risk found.
