... of deformable fixture supports. The developed model was validated numerically and experimentally for different workpiece geometries and various types of loading. This model resulted in one to two orders of magnitude reduction in computation time when compared with the finite element models, with prediction...

... motion analysis. In the model, for undeformed chip thickness determination, an analytical model is first established to describe the sweep surface of cutting edge during the five-axis ball-end milling process of curved geometries. The undeformed chip thickness is then calculated according to the real...

... to explore the effects of cutting speed, nominal tool load, and AFM probe mounting angle on groove geometry, tool wear, effective rake angle, and chip formation. Lastly, an experiment is described in which a long curvilinear groove is cut. It is shown that the most well-formed grooves were cut and acceptable...

.... The model considers the complex geometry of a thrilling tool and the unique tool paths associated with the thread milling operation. Experiments have been conducted to validate the developed model. Comparison of the average torque and forces between experiment and simulation results shows that the model...

... stability limits. Once the process damping coefficient is identified, it is related to the instantaneous indentation volume by a coefficient which can be used for different cutting conditions and tool geometries. In determining the indentation coefficient, chatter test results, energy, and tool indentation...

... of the required force for performing the ECAE process is made by considering a full three-dimensional geometry with a rectangular cross section. From this analysis, the influence of the geometric and the material parameters is studied by considering both friction and strain hardening materials. By using the upper...

.... However, synthesis of the coating on components of complex geometries with controlled phases is still a challenge. In this paper, we present the results from the exploration of electrostatic spray coating of hydroxyapatite nanoparticles and the interaction of particles with laser. The nanoparticles were...

...Stephen P. Radzevich A novel descriptive-geometry-based (DGB) approach for determining of limitation on parameters of rotary shaving operation of shoulder gear is reported in the paper. The paper covers determination: (a) of the maximum feasible outside diameter of the shaving cutter; (b...

... for restricted contact cutting extended to take into account the presence of a groove on the drill rake face. The applicability of the model for arbitrary groove geometries has been ensured by eliminating the use of grooved drills in the calibration process. Four different combinations of groove geometries have...

... for various flute geometries. The model considers the chips in the flutes as granular solids and determines the chip-evacuation thrust and torque from the normal and lateral pressure distributions in the chips that fill the flutes. The model requires two coefficients of friction that are established via...
