Abstract
Burr is usually formed and attached to the edges of surfaces during machining operations. It needs to be removed otherwise it can cause problems at the assembly stage ofprecision parts. If the minimization, or elimination, of burrs becomes possible, then time-consuming and costly deburring operations need not be performed. In this work, face milling experiments have been carried out on aluminium blocks to observe the influence of machining conditions and exit edge bevel on exit burr formation. Results obtained in vertical milling in dry conditions are presented and the obtained results are analysed using the analysis of variance (ANOVA) test to isolate the significance of the observed effects. It is found that exit edge bevel has the most significant effect in the present experiments. A 15° exit edge bevel angle is shown to lead to negligible levels of burr formation.
