Nowadays, vibration-assisted drilling (VAD) is used to decrease the exit burr size. However, further analysis of the VAD burr formation mechanism is required. A mathematical burr prediction model of low-frequency VAD is proposed for the aluminum 7075-T6 alloy cutting.

(PDF) A Bayesian network for burr detection in the One of the most important processes in the aeronautical sector is drilling. The main problem associated with drilling is burr. There is a tolerance level for this burr and it cannot exceed 127 microns, which would provoke structural damage and other Investigation on the Exit Burr Formation in Micro MillingThe burr on micro part has harmful effect on the dimensional accuracy and service performance. The original control of exit burr formation during micro milling is desirable and advisable. In this paper, the formation mechanism of exit burr was studied based on the varying cutting direction during micro milling. Three exit burr control strategies were concluded, the material properties (PDF) On the Three-Parameter Burr Type XII Distribution Properties of Burr Type XII Distribution with Three Parameters Let X be a random variable having Burr XII (c, k, ) distribution, and then the cumulative distributions Function (cdf) have the form given by Tejeda and Barry (2008) as follows:k x c F x 1 1 ; x 0, c 0, k 0, 0 , (1) where c >0 and k >0 are the shape parameters and is the scale Sensors Free Full-Text Simultaneous Burr and Cut The quality is grouped in the categories good cut, cuts with burr formation and cut interruptions. Indeed, our results reveal that both cut failures can be detected with one system. Independent of the neural network design and size, a minimum classification accuracy of 92.8% is achieved, which could be increased with more complex networks to 95.8%.

Exit Burr Size. The exit burr morphology and size vary with the feed per tooth when a p = 10 m and n = 16,000 rpm are shown in Figure 11. It is found that when the feed per tooth is less than tool cutting edge radius, the exit burr width rapidly increases with the decrease of feed rate. Force Prediction and Cutting-Parameter Optimization in Optimization of cutting parameters in micro-milling is an important measure to improve surface quality and machining efficiency of the workpiece. Investigation of micro-milling forces prediction plays a positive role in improving machining capacity. To predict micro-milling forces and optimize micro-milling cutting parameters (per-feed tooth (fz), axial cutting depth (ap), spindle speed (n
