| Abstract | ||||
| Modern industrial operations wouldn't accept old defects to be present in the new products, especially that many products include electronic parts or connections that are very sensitive to the level of finish. Burr formation in drilling operations causes products to be rejected or sent for deburring. Since deburring is a costly and non-value-added operation, the understanding and control of burr formation is a research topic with high relevance to industrial applications. In order to investigate and improve burr formation, a spring was mounted over the bench drill spindle to measure the cutting force and attempt to know its influence on the burr outcome of the operation. | ||||
