The reliability of small precision mechanisms depends on the production of burr-free, sharp-edged parts. An investigation was conducted to determine how these requirements could best be maintained. The study included investigating the capabilities of the 24 major deburring processes and finding other techniques for minimizing burr-related problems and assuring sharp-edged parts. It has been concluded that four approaches can be used to provide the required quality: prevent burrs from forming; minimize burr size by proper machining conditions; design parts to minimize deburring problems; and improve existing deburring techniques by defining and increasing capabilities.
