Assessment of Deburring Costs in Industrial Case Studies

Owing to the fact that deburring is considered a non-added value operation, little attention is paid to estimating its real cost. However, deburring expenses in manufacturing processes can be significant depending on the workpiece or sector considered. They can vary from 2 to 3% for mass production of relatively common parts in automotive sector to 9-10% in the case of aeronautics for small batches series or mass production of complicated parts. This figure can reach even higher values in other sectors such as medicine. Seven case studies from different manufacturing sectors (aeronautics, automotive, heavy transport, oil piping transport...) will be outlined in this paper in an attempt to assess real deburring costs and other issues dealing with the reasons why deburring is carried out and the methods used for burr removal.
