Abstract
A phenomenon similar to the formation of chips is the formation of burrs at the end of a cut. Burrs are
undesirable because they present a hazard in handling machined parts and can interfere with subsequent
assembly operations. They must be removed in subsequent deburring processes to allow the part to meet
specified tolerances.
In conventional machining, there are a lot of deburring processes to remove burrs. Except for the
cost of the edge finishing operation, deburring processes in the conventional machining are not big
problem. In the micro-machining process, however, burr is very hard to remove. Conventional deburring
operation cannot easily apply to micro-burrs.
The purpose of this report is to research the previous work in micro-machining and to study burr
formation in micro-machining.
