In this work I redesign a device used in the fiberglass sheet molding with roving. The device cuts the roving in pieces of approximately six or seven centimeters and lays them on the mold of the part to be made. Today these cutters have to be attached to the chuck of a regular handheld electric drill. The description of this task from an ergonomic standpoint revealed several points that deserved to be studied and improved. One of the most significant problems concerns the operator s position during sheet molding, which involves muscular and bone injury risk. This analysis serves as a basis for the designing of a new roving cutter that improves the operating conditions. The main goal of this work is to create alternatives for the development of fiberglass roving cutters. Such a study is relevant because it is based on the following three main aspects: (i) a better understanding of the operator s role in the work of machinery like hand-held electric drills; (ii) the implementation of an interdisciplinary project bringing together the areas of Mechanical Engineering, Industrial Designing, Production Engineering, and Materials Engineering; (iii) the opening for new research on industrial tools and development of new product designs.
