Because of nonuniform chip thickness, tool runout and complex interactive effects between cutting process parameters, milling burr formation is a very complex mechanism. Therefore, research and close attention are still needed in order to minimize and control milling burr formation.
Therefore, burr minimization and control become more important for micro milling. Currently developing effective burr control techniques in micro milling remains a pressing task. ... Material removal in the conventional milling process is dominated by the shearing action of the tool, while in vibrationassisted milling the material removal ...
The primary burr is much larger in size compared to the secondary burr and needs to be removed by a deburring operation subsequent to machining, for effective performance of precision parts. In this paper we present a strategy for minimizing burrs in face milling.
The milling characteristics experiments with typical micro three dimensional parts are done by the developed 3axis micromilling machine tool, and the micro burr formed in micromilling process is observed and analyzed. Burr formation and its influence factors in micromilling process are studied and general influencing rule of each factor to burr formation is summarized.
enhancing the geometry of the device. As minimization of micro burrs still remains a key test in micro machining, not many researchers have worked in this field. The main aim of the research work is to present finite element analysis of flat end mill micro cutters used in micro milling .
In this paper a review of various methodologies for burr prediction and minimization in face milling is presented. In particular, the authors look into the geometric solutions employed, which typically consist of understanding and modifying tool engagement conditions. The extent of applicability of ...

The removal of burr consumes about 15% of man power and cycle time of manufacturing. The earliest report about burr was with the punching operation. The other operations like turning, milling, grinding also produce burr during machining of materials. However, the mechanism of burr .
Recent Advances in Burr Height Minimization in MicroMachining 386‐2 (2012) and Zheng et al. (2012). Many researchers are working in the area of minimization of micro burrs in micro milling/drilling, still, burr minimization remains a key challenge in micromachining The main aim of this work is to present the work
Fabrication of microchannels on titanium alloy with micromilling is a tough challenge due to the difficultly to remove the burrs formed in machining process. A novel method to gelatinize workpiece surface to control the generation of burr as well as the optimization of cutting parameters are investigated in this paper. Differences existed between the process of micromilling and that of ...
Although the machinability of most aluminium alloys can be classified as relatively easy when the tool wear and the cutting energy are considered, these materials could however raise some concerns when the chip formation and the burr formation are of concern. Burr formation, a phenomenon similar to ...
Suppression or elimination of burr formation at the exit edge of the workpiece during drilling is essential to make quality products. In this work, low alloy steel specimens have been drilled to observe burr height under different machining conditions. Taper shank, uncoated 14 mm diameter HSS twist drills are used in these experiments.
Therefore, burrs were formed on low melting point alloy, which were removed by melting it off afterward and the burrsfree component was thus achieved. Experiments were carried out on a micro milling machine and aluminum alloy was machined with micro end milling tools.
Burr Minimization and Removal by Micro Milling Strategies or Micro Peening Processes. A. Kienzler, M. Deuchert, V. Schulze ... About these proceedings. Introduction. 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 ...
In the micromachining process, however, the burr is usually very difficult to remove and, more importantly, burr removal can seriously damage the workpiece. Conventional deburring operations cannot be easily applied to microburrs due to the small size of parts.
Burrs are generally plastic deformation of the work piece after machining process. Deburring can reduce burr formation but it is time consuming and increase the production cost. By changing some of the input parameters like Spindle Speed, Feed Rate,

Burr Management in Machining, 12 to 13 December, 2019, Delhi | As long as there has been metal cutting, there have been burrs—an unwanted side effect of the process. Barring a revolutionary change, burr formation will always be a problem. With a few exceptions, conventional machining techniques always produce burrs. Burr prevention requires both conventional and nonconventional approaches.
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. ...
