Isotropic Mass Finishing for Surface Integrity and Part Performance

摘要

Mass media finishing techniques (barrel, vibratory, centrifugal and spindle finish) can be used to improve part performance and service life, and these processes can be tailored or modified to amplify this effect. Although the ability of these processes to drive down deburring and surface finishing costs when compared to manual procedures is well known and documented, their ability to dramatically effect part performance and service life are not. This facet of edge and surface finish processing needs to be better understood and deserves closer study and documentation. Industry and public needs would be well served by consortium of partners at the industry, university and governmental agency levels capable of researching all aspects of surface texture and surface conditioning related to part functionality, performance and service life. At the time of this writing, possible FAA intervention bringing the use of manual deburring techniques on commercial aircraft engine components under closer control are apparently being considered.
