Abstract
Laser micromachining processes cut material by melting the workpiece with thermal energy. The solidified material adheres to the cut edges and forms burrs, which cause many serious problems in manufacturing. Using existing conventional techniques, it becomes difficult to remove the heat-affected hard burrs that project inside capillary tubes. The aim of this research is to develop a deburring process for burrs that project into areas hard to reach by conventional techniques. This research applies the magnetic abrasive finishing process to capillary tube deburring. Through the manipulation of the magnetic field at the finishing area, the process controls the motion of the magnetic abrasive introduced into the tubes. This study includes a discussion of the principle for the internal deburring process of tubes with multiple slits and the refinement of the finishing machine. Experiments demonstrate the deburring characteristics of multiple laser-machining burrs projected inside 0.0165 in (419 μm) inner diameter tubing.
