“…Hocheng et al [ 28 ] analyzed the frequency and size of roughness profile, and established the relationship between surface roughness model and tool geometry, low frequency vibration, and measurement accuracy. Bougharriou et al [ 29 ] developed a surface roughness model for R t that can accurately predict different cutting depths and feed rates. Sun et al [ 30 ] established the surface roughness models of R a and R q for wedge angle, cutting edge shape and feed rate.…”

To study the effect of material properties on the surface morphology of potassium dihydrogen phosphate (KDP) crystals, an ultra-precision fly cutting machine tool with a single-point diamond tool was used to perform a cutting experiment on (100) crystal plane of the KDP crystal. The elastic modulus, shear modulus, hardness, and dislocation of KDP crystals are taken into the cutting force model by introducing the strain gradient plasticity theory. Since the size effect and dynamic response will affect the surface roughness during ultra-precision machining, the surface roughness of workpieces in ultra-precision fly cutting is hard to predict. Based on the previously established strain gradient plasticity theoretical model, cutting force model, and the dynamic characteristics of the ultra-precision fly cutting system, a surface morphology prediction model under the influence of KDP crystal material properties was established. Finally, the accuracy of the surface morphology prediction model was verified by ultra-precision fly cutting experiments, and identified the frequency range of the characteristic signal caused by the anisotropy of the KDP crystal from the frequency, thereby verifying the KDP crystal material properties has a significant effect on the surface of the machined workpiece roughness.

“…They developed a correlation between asperities height and burnishing pressure through series of basic deformation theory and geometrical model of asperities. Boughario et al [11] demonstrated that the surface profile of burnished sample depends to kinematic of the motion of burnishing ball over the surface of the sample. In their model, the surface profile depends to the feed rate and burnishing depth.…”

In mechanical based machining processes, the surface topography is generated through series of hierarchical pattern. Plastic deformation as result of contact and kinematic of motion are two main factors which determine evolution of surface generation. To basically optimize the surface quality, accurate predictive model of surface generation and constraints are required. In the present work, analytical models of dimple formation and hierarchical surface generation in ultrasonic assisted ball burnishing process are proposed. Pileup and sink-in as two phenomena of indentation during both of loading and unloading phases were taken into the developed models. Considering interaction of indentation profile and kinematic of motion, three-dimensional surface topography and surface roughness are also analytically predicted. A criterion for surface failure is defined to perform process without any erosion. Confirmation of results have been made by series of single trace and multitraces burnishing experiments on AA6061-T6 and AISI 1045. The results of indention profile, surface topography, roughness and failure criterion which were derived from predictive models were completely consistent with confirmatory experiments.

The tool geometry is one of the most effective factors on the surface quality of turned products. This study aims to investigate the influence of different tool geometries on surface roughness of turned aluminum alloy 1050 that has not been documented well in literature. Various levels of simultaneous cutting edge angles, included angle and tool nose radius were selected. Different single point tools of HSS (5% cobalt) were prepared. Four categories of experiments were performed according to the levels of the included angle. Each category consisted of five sets of tests based on the proposed levels of tool nose radius. The tests within each set were arranged according to the selected levels of end cutting edge angle with constant or simultaneous cutting edge angle. All tests were conducted on a heavy duty lathe machine, while the produced surface qualities were measured by a stylus type roughness tester. Experimental results deduced a proportional relationship between surface roughness and end cutting edge angle with constant cutting edge angle. Also, the results showed that the surface roughness increases with the increase of simultaneous end cutting edge angle up to a certain point called focus point angle after which decreases. Furthermore, the tool nose radius has an inverse effect on roughness, but the included angle affects positively. Finally, the maximum values of simultaneous end cutting edge angle that can produce acceptable surface finish were defined in accordance with the tool nose radii and included angles.
