Abstract
Two
types of exit burrs, primary and secondary burr, are formed in milling
operations depending on a number of parameters including cutting conditions,
cutter geometry, work part geometry and material properties. The primary
burr is much larger in size, and is difficult to remove in subsequent
deburring process compared to the secondary burr. In this work, an algorithm
was presented for the tool path planning of face milling with which
the total length of primary burrs are minimized by selecting an appropriate
tool feed direction. This algorithm is more concise than previous work
and applicable to work parts with curved edges and inner profiles.
