TABLE OF CONTENTS A manufacturer's goal is to increase the efficiency of part passage through the deburring area and to increase the quality of the parts. For this to happen the manufacturer or plant operator must understand and be able to state exactly how this goal is to be met; otherwise, potential for finishing improvements will not be met fully. Chapters 2 and 3 discuss this topic in some depth.
Five keys to improving efficiency and quality are:
The understanding of the real edge and surface needs of each part.
The discovery of different ways to reduce the problems caused by specific burrs.
The understanding of the economics of mass finishing.
The determination of the value of deburring to specific situations ("value engineering").
The determination of the root cause of issues.
In many instances, removal of sharp edges is the real requirement, not full burr removal. When this is the objective, notes like, "Roll over burrs are acceptable on edges a, b, c, etc." will allow operators to reduce cycle time and meet customer needs. The notes may say, for instance, "rolled edge burrs permitted" or "remove all burrs visible to the naked eye along all edges" or "burr permitted at this location provided loose fragments not detectable or produced via shop air nozzle at 90 psi at 2 inches from part in 10 seconds." Chapter 2 and 3 have more examples of requirement notes and (Gillespie 1999).
Chapter 2 provides the background to understand...
