Formation and Control Technology of Top Burr in Micro-Milling

Abstract

Abstract. Burr formed during micro-milling slot has the most direct effect on surface quality and dimension accuracy of work-piece. Compared with other positional burrs, top burrs having the biggest dimension make the subsequent de-burring operation more difficult. To analyze the effect of spindle speed, cutting depth , feeding per teeth and blade radius on top burr size, Al6061-T6, used as research object, was conducted on a 5-axis machining center with the single factor method. Effect regularities of the process parameters on burr dimension were preliminarily revealed, active control of burr dimension during micro milling operation could be possible on the basis of the experiment.

Study on the Mechanism of Burr Formation by Simulation and Experiment in Ultrasonic Vibration-Assisted Micromilling

“…In addition, ultrasonic vibration has the most obvious effect on milling at medium and low cutting speed. Zhang et al [ 31 ] also pointed out that the burrs become more with the increase in the cutting speed. Similarly, as shown in Figure 13 , it was also observed in the above phenomenon in this experiment (in the Figure, in each groove, the down-milling side is located at the upper side).…”

Image Processing Approach to Investigate the Correlation between Machining Parameters and Burr Formation in Micro-Milling Processes of Selective-Laser-Melted AISI 316L

“…The presence of burrs negatively impacts the quality and functionality of micro-parts and features. It presents a major obstacle in micro-milling operations, with the small size of the burrs making deburring a challenging task [ 43 ]. In line with this direction, a burr reduction mechanism was developed by Chen et al [ 44 ] using vibration-assisted micro-milling for the reduction of burr parameters.…”
