Réalisation d'instructions de travail pour l'ajustage sur cellules robotisées

This document is the result of my work in the end study’s internship, in order to obtain my DUT Mechanical Engineering at the University of Angers. I made this internship of eleven weeks within society HALGAND, located at Saint Brévin les Pins, next to Saint Nazaire. My mission within this company was to realize work instructions for deburring of robot cells. To explain this mission, first we are going to explain the goal, and then we are going to present the different steps to complete this mission. The goal of this mission is to improve the manufacturing process of parts, and so to improve the production. All of this, by establishing working instructions allowing automated deburring operations on parts. The first thing was to have a provisional repertoire of parts which are machined on robot cell on which I worked. With this list, I determined articles on which I had to make modifications. Indeed, improvements must be made on parts having the largest machining time for month on the robot cell. The second step was to make an inventory of parts previously targeted, to identify different deburring there are to perform during machining. So, I had to analyze computer machining simulations and to discuss with the machine operators to know the different deburring already performed during machining, and those remaining to complete. An inventory of tools for deburring which are presents in the workshop and deburring stations has been also realized. I also had to look for innovative tools in the field of automated deburring, which were not present in the workshop. Then, I formed a work instruction file already ready to be filled to facilitate the creation of work instructions. So I had to implement a suitable format and to choose an interesting and relevant location for work instructions for deburring of robot cells. The choice of location was to be decided with the opinion of machine operators, who are, of course, the first people concerned by these work instruction. And finally, the final work was to realize work instructions of the selected parts, in order to integrate deburring operations during the machining phase. Inside these work instruction
should include all necessary information for the understanding of the work required.
