EXPERIMENTAL INVESTIGATIONS OF SIDEWARD BURR FORMATION IN ROTARY MACHINING

Burrs can be formed on the feed mark ridges and the edges of the machi ned parts in machining operations. These burrs are undesirable in term s of the surface quality, the precise dimensioning of the machined par ts and the safety of operators. This paper demonstrates the effectiven ess of using a rotary tool on minimizing the sideward burr formation i n machining. In particular, the experimental relationships between the size of sideward burr and the cutting parameters (including tooling m echanism) are established first in rotary machining. Methods to contro l the size of sideward burr are then explained. The possible applicati on of a rotary tool for deburring operations while engaged in machinin g is also explored.
