Download or read book Burrs Analysis Control and Removal written by Jan C. Aurich and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many machining operations burrs cannot be avoided. They can affect the functionality and the safe handling of the workpiece in the subsequent processing, and have to be removed by a special deburring process. Toleration of burrs, which are not part of functional edges, depends on their respective shape and size. High inspection effort is necessary to guarantee the workpiece quality. Therefore, the research results on burrs, with a focus on burr analysis and control as well as on cleanability and burr removal based on the presentations held at the conference are valuable for researchers and engineers in manufacturing development.

Available in PDF, EPUB and Kindle. Book excerpt: Burr formation is a common problem in metal drilling processes leading to additional production costs in manufacturing. Since burrs cannot be prevented through process control and parameter optimization, obtaining a better understanding of the mechanism of the burr formation process and potentially paving the way for more appropriate development models that could mitigate the process is essential. Currently, the complex tool geometry and the dynamic nature of metal drilling pose challenges in the analysis of the drilling mechanics, and consequently, the burr formation process, thereby constraining researchers to approach the problems through the development of empirical models or alternative methods difficult to replicate. The objective of this work is to develop a new and novel method using energy analysis to identify unique points of process changes that characterize the breakout burr formation mechanism during the metal drilling process. The method developed identifies the onset of the burr breakout phenomenon, and also identifies critical points between the onset of the process and completion of the through-hole drilling process. Using a series of drilling experiments on Al 6061-T6 with standard twist drills, real-time thrust and cutting power data were collected and analyzed using a newly developed energy-difference approach (EDA). The resulting analysis was successfully mapped to the burr breakout phenomenon and validated using photomicrographs observation and microhardness testing at various points ahead of the drill point during burr breakout. Using an original approach through-hole drilling was separated into 3 primary sections identifiable using energy analysis. This work allowed for the third - critical zone, which is of primary interest in burr formation to be identified and isolated for analysis. Using the EDA process, 4 specific points of interest that characterize the actual burr formation mechanism were identified and observed for the first time: burr breakout initiation, deformation zone depth ahead of the drill point, ploughing initiation, and ploughing dominance. By identifying and quantifying the positions and depths of these critical points in the breakout burr formation, future work will allow for proper modeling, prediction, and minimization of breakout burrs.

Available in PDF, EPUB and Kindle. Book excerpt: In the aerospace industry, burr removal is a very important part of the manufacturing process. Stacks of material on sections of an aircraft are assembled and drilled by hand. Due to extensive burr formation the sheets must be destacked so that burrs can be removed and then the stacks are reassembled and fastened together. If burrs are minimized in the drilling process, this would reduce the necessity for the sheets to be destacked and deburred. : One approach to minimizing burrs is to lower the thrust force in drilling through suitable modification of the drill geometry such as the use of a step drill. Although prior researchers have analyzed different drill geometries such as step drills and their effect on hole exit burr formation in the drilling process through experimentation, no work has been reported on modeling and analysis of step drilling forces and their relationship to burr formation as a function of the step drill geometry parameters. Consequently, this thesis focuses on the modeling of the thrust force and torque for step drills and analyzes their relationship with burr size as a function of the step drill geometry parameters. In the first step, a mechanistic model for thrust and torque in drilling is implemented for a standard twist drill. This mechanistic model is then adapted to predict the thrust and torque for a step drill. Subsequently, experiments are performed to validate the mechanistic model and to evaluate burr formation with standard and step drills. The influence of thrust and torque on hole exit burr formation is analyzed for different step drill geometries and experimental feeds and speeds. The results show that the predicted thrust and torque values for both drill geometries are in good agreement with measured values, although the torque model consistently underpredicts. For standard drill geometry in the calibration tests, the average error in the thrust prediction is 7.09% and the average error in the torque prediction is -18.05%. In validation tests, the average error for predicted thrust is 2.29% and the average error for predicted torque is -18.46%. For the step drill model the average error in thrust is 0.72% while the average error in torque is -8.72%. In addition, a reduction in the predicted thrust force for a step drill relative to the standard twist drill is found to correlate well with a reduction in the measured burr size. However, further reduction in the thrust force by varying the step angle and diameter ratio do not correlate well with the measured burr size. Likely reasons for these results are presented in this thesis.
