Due to its challenging manufacturing and intricate morphology, the aluminum alloy transmission intermediate shell used in vehicle transmission has been the focus of many academic studies. In this study, the three-dimensional cutting model is condensed to a two-dimensional cutting model and utilized to simulate the finishing process of an aluminum alloy workpiece using the finite element modeling program DEFORM-3D. Through orthogonal testing and range analysis, the impact of integral end mill side edge parameters on cutting performance was investigated. It is determined that tool chamfering has a greater impact on cutting performance than tool rake and relief angles, that chamfering width has the most impact on cutting force, and that chamfering angle has the greatest impact on cutting temperature. The workpiece's surface roughness is tested during a cutting experiment, and an analysis of the data reveals that the finite element simulation model is accurate and the orthogonal test method is reasonable. The tool chamfer has a greater impact on roughness than the tool rake angle and relief angle. The tool settings are further optimized using the firefly method. By examining the data, it is determined that the prediction model is correct and the optimization model is reasonable. The cutting efficiency is higher and the surface quality is better when the chamfer width is 0.17 mm and the chamfer angle is 7.3° or 18.3°. Therefore, optimizing the side edge parameters of the integral end mill during the finishing process of a thin-walled aluminum alloy shell has practical technical value.

Hrapavost obrađene površine je jedan od najvažnijih parametara koji određuju funkcionalne osobine i kvalitet obrađenih delova. Iz tog razloga, cilj ovog rada je ispitati uticaj parametara rezanja na hrapavost obrađene površine pri glodanju biokompatibilne legure titanijuma Ti6Al4V. Pored toga, izvršena je i optimizacija parametara rezanja sa ciljem postizanja što manje hrapavosti obrađene površine. Za pronalaženje optimalih vrijednosti i analizu uticaja parametara rezanja na hrapavost obrađene površine korištena je Taguči metoda. Posmatrani parametri rezanja u ovom radu su brzina rezanja, pomak i dubina rezanja. Sprovedena analiza je pokazala da prilikom glodanja biokompatibilne legure titanijuma Ti6Al4V na hrapavost obrađene površine najviše uticaja ima brzina rezanja. Nakon izvršene analize uticaja i optimizacije parametara, određena je i linearna zavisnost između posmatranih parametara rezanja i hrapavosti obrađene površine.

“…There are several papers published in recent years that have been devoted to the simulation of various aspects of end milling, including vibrations [30], energy consumption, carbon emissions [31], cutting forces [32], tool wear, material removal rate, surface roughness [33], and temperature in the cutting area [34]. In particular, Cao et al [30] studied chatter, a self-excited vibration accompanied by unstable, chaotic behavior and largely abnormal fluctuations of end mills.…”

“…A set of milling experiments (at end milling of AISI1045 steel with coated carbide end mill) was performed to verify the analytical results. To comprehensively evaluate the cutting performance, Zhao et al [33] developed fuzzy comprehensive evaluation models, which considered the tool wear, material removal rate, surface roughness, and dimension error for rough and finished end milling, respectively. Baohai et al [34] considered a new analytical model-based method to predict the temperature of the cutting tool in end milling.…”

The paper deals with the challenges of the application of two-component end mills, which represent a combination of a carbide cutting part and a shank made of cheaper structural material. The calculations of strains and deformations of composite mills were carried out in comparison with solid carbide mills, with the use of the finite element method. The study also involved the comparative analysis of accuracy parameters of machining with monolithic mills and two-component mills with various shank materials. As a result of the conducted cutting tests in milling aluminum alloy with monolithic and two-component end mills with specially developed multilayer composite nano-structured coatings, it has been found that the use of such coatings can reduce strains and, correspondingly, deformations, which can improve the accuracy of machining. Thus, the application of twocomponent end mills with multilayer composite nano-structured coatings can provide a reduction in the cost of machining while maintaining or even improving the tool life and machining accuracy parameters.
