Experimental Study On Several Typical Centrifugal Barrel Finishing Of Aeronautical Materials Parts

Finishing technology is a processing method that can enhance the quality of the material surface after the completion of the specifications and dimensions of the material processing.Finishing technology is now widely used in aviation, aerospace, automotive, rail transportation and other fields. Centrifugal finishing is a kind of finishing methods with low cost, high efficiency, easy operation and many other advantages. Currently, centrifugal finishing the specific material part is still in the exploratory stage. In order to obtain the optical processing characteristics of the centrifugal method of finishing machining the workpiece, fourteen kinds of materials specimens were finishing with different purposes in the paper, but also centrifugal finishing the actual test part. Work and achievements of this paper are as follows:(1) Analyzing principle of centrifugal finishing, and selecting experiment methods and parameters.(2) Conducting centrifugal finishing experiments of fourteen kinds of materials specimens. Roughness variation rules were obtained under finishing duration variations and different specifications abrasive conditions. At the same time, the optimum of abrasive finishing options was accessed.(3) Conducting centrifugal finishing deburring experiments of fourteen kinds of materials specimens with small burrs. The relationship between deburring and finishing duration was obtained. At the same time, the relationship between specimens surface material removal, rounded edges values and finishing duration variation, size specifications was accessed, also more excellent abrasive finishing options were received.(4) Conducting centrifugal finishing deburring experiments of fourteen kinds of materials specimens with big burrs. The relationship between deburring and finishing duration was obtained. At the same time, the relationship between specimens surface material removal,rounded edges values and finishing duration variation, size specifications was accessed, also more excellent abrasive finishing options were received.(5) Conducting centrifugal finishing experiments of four actual parts. The relationship between specimens surface material removal, specimens surface roughness and finishing duration variation, size specifications was accessed, also better abrasive finishing options were obtained.
