Summary: ABSTRACT: In this study, abrasive flow machining (AFM) was utilized to remove burrs from the edges of milling specimens. The deburring performance was characterized based on experimental observations and validated through tests and simulations. A new objective function that can predict the extent of deburring was proposed and proved to be effective.

Summary: A new drilling approach using controllable force for clamping the specimen was implemented to investigate the influence of cutting and support conditions on thrust force, delaminations, and burr factor in drilling woven GFRP composites. A series of ASTM tests were conducted to determine mechanical properties and predict the critical thrust force for delamination initiation. Accurate measurement of delamination and burr areas was achieved using an inexpensive image processing technique.

Summary: This study attempts to remove milling burrs using various types of flow guides and investigates the effects of process parameters such as the shapes of the flow guides and viscosity of the abrasive fluid. An index representing the suitability of the flow field for deburring is suggested based on flow velocity and shear stress near the burr edge. The index values obtained from CFD simulations seem to correspond to the deburring performances of the flow guides.

Summary: This study investigates an ultrasonic-assisted abrasive micro-deburring process that can efficiently remove burrs from high-aspect-ratio micro-pillars. The process achieves high deburring efficiency while maintaining the integrity of the micro-pillars, with burr reduction rates as high as 88.75% for Al 6061 and 90.1% for copper in a short processing time of 10 s.

Summary: In this paper, the mechanisms of top burr formation in micro milling were analyzed, and experiments were conducted to study the effects of machining parameters on the morphology and size of top burr. It was found that the top burr is caused by unexpected material plastic side flow and unseparated chips connecting on the top side. Optimal machining strategies were suggested to minimize top burr.

Summary: The presence of burrs on micro parts can have negative effects on dimensional accuracy and service performance. It is crucial to control the formation of exit burrs during micro milling to improve machining outcomes. Research shows that the formation of exit burrs is due to changes in material flow paths at the exit surface, and strategies such as increasing support stiffness and optimizing machining parameters can effectively control their formation.

Summary: This study investigates the behavior of circular winding concrete filled GFRP tubular columns with various inner section shapes. Through axial compression tests and numerical analysis, different parameters of columns were tested and analyzed. The failure mode, ultimate capacity, ductility, and stiffness of the columns were analyzed, and a calculation formula was proposed to predict the ultimate capacity of different section GFRP profile strengthening concrete-filled GFRP tubular columns. The formula was validated using a finite element model.

Summary: This paper proposes a general method for automating deburring using a 3D vision sensor, which is robust to missing data and sensor noise. The method utilizes data-driven features for aligning clean CAD models to the noisy and incomplete geometry of an RGBD scan, improving registration accuracy. Additionally, a 3D-vision based automatic burr detection and height estimation technique is presented and compared to high resolution CT scans.
