Industrialisation d'un procédé de perçage-ébavurage sur lisses et rails

Abstract : This report presents the industrialization of a drilling-deburring process. The aims of this project is to determine the parameters for the good use the drilling-deburring tool and to define the limitations of the process to meet the customer’s requirements. The drilling-deburring tool is constituted with a twist drill and a tool body containing control bolt, a spring and a blade allowing the blade to be retracted without spoiling the bore. It is this technology that permits a front and back deburring. This report presents the bibliographic review which was essential to apprehend all the parameters related to the burr formation during drilling and to the breaking of corners necessary to remove those burrs. This study led to the solution of the supplier Heule which was implemented. In a second phase are explained the different trials which permitted to define the tool cutting data to launch the first phase of industrialization on the numerically controlled machine CAURALIS. Besides are developed the different technical problems, notably the tool overall size, resulting from these trials and the chosen solution to remedy. Finally, as the cutting data is set up, the parameter to be worked on to qualify the process is the spring pressure. Indeed we had to determine if this pressure had an impact or not on the quality of the final edge breaking, and if it had to be put under surveillance.
