Based on loads analysis and failure analysis for high speed face milling cutter with indexable inserts, the failure criterion of cutter was propounded, and the finite element model of cutter was established. By means of modal analysis and stress field analysis, the law of influence of the structure and elements of cutter on the safety of cutter was acquired, high speed face milling cutter for machining aluminum alloy was developed.

Thin-walled parts are commonly used in the aerospace sector. However, there are serious machining challenges, such as deflection, deformation and vibration. The final thin-walled component machining will deteriorate the dimensional accuracy and surface quality. This is due to the vibration and deformation that occurs during flexible milling of thin-walled structures since the workpiece rigidity is lower than the cutting forces of the milling cutter. The gradual reduction of the thin-wall thickness during the end milling process results in significant deflections and deformations due to its low

In this paper, a new experiment procedure is proposed to study the influence of cutter parameters and clamping methods on the stability of the milling process of thin-walled blade. A dedicated fixture is designed to carry out the experiment. Simulation results show that the new clamping system can enhance the rigidity of thin-walled blade to reduce cutting deformation and chatter vibration phenomenon. Then, cutter and cutting parameters can be optimized properly to make the system obtain high rigidity and high performance stable milling process. Industrial application indicates that the new sy

This study has developed a model in order to show the relationship between deflection of the low-rigidity processing system such like thin-walled component and the flexible milling force. The new model takes the deflection of cutter-workpiece system into account. The cutting force is analyzed simulatively by utilizing modified Newton–Raphson iterative algorithm. The simulative results show that the total normal deflection of workpiece–cutter system is the main factor affecting the change of cutting force.

Plunge milling is used to remove excessive material rapidly in roughing machining. The cutter feed in the direction of machine spindle which has the highest structural rigidity. Through the single factor experiment of plunge milling a P20 die steel, this paper investigates the influence of side step, forward step, cutting speed, feed per tooth on cutting force. On this basis, the principles of optimization of interpolation milling parameters are proposed. This guidance of mold production practice has significant reference value.

Plunge milling operations are used to remove excess material rapidly in roughing operations. The cutter is fed in the direction of the spindle axis which has the highest structural rigidity. This paper presents a comprehensive model of plunge milling process by considering rigid body motion of the cutter, and three translational and torsional vibrations of the structure. The time domain simulation model allows prediction of cutting forces, torque, and vibrations while considering tool setting errors and time varying process parameters.

Experimental studies of the effect of adjacent teeth pitch diversity on self-oscillation excitations in a cutting manu-facturing system having a reduced rigidity in normal line towards treated surface, are presented. The possibility for effective suppression of self-oscillations during face milling by controlling teeth pitch of the cutter is given. A stepwise teeth diversity making possible to suppress self-oscillations by 50 % has been found.

Cr12MoV die steel is a typical high-strength and high-hardness material. Because of the high hardness of Cr12MoV die steel, which is approximately 50–65 HRC after quenching, and the tool’s weak rigidity, cutting vibration, and tool deformation are inevitable during the cutting process. In this paper, a model for predicting the surface topography of a convex curved die steel machined by a ball-end milling cutter was established. In addition, the surface springback of the workpiece is considered. According to the surface characteristics of the convex curved workpiece, the vector algorithm and tr

For finishing gear cutting of wheels of a large module, a method of intermittent rolling is proposed usingnon-modular disk cutters (the dimensions of the cutter do not depend on the module), equipped with ceramicplates and special milling calipers with a single-spindle and two-spindle cutting scheme, taking into account theprovision of all basic installation movements of high-speed non-modular disk cutters.

The finite element formulation is studied in this paper to predict static form errors in the peripheral milling of complex thin-walled workpieces. Key issues such as cutter modeling, finite element discretization of cutting forces, tool–workpiece coupling and variation of the workpiece’s rigidity in milling are investigated. To be able to predict static form errors on the machined surface of complex form, considerable improvements are made on the proper modeling of the material removal in milling and the iterative calculations of tool-workpiece deflections.

Торцовые фрезы, входящие в состав агрегатной фрезерной головки (АФГ), должны обладать достаточной жесткостью для обеспечения качества обработки [1]. От жесткости фрезы напрямую зависит возможность применения высоких режимов резания – подачи, глубины резания. Для увеличения жесткости в конструкциях АФГ используют упорные подшипники качения и корпуса фрез повышенной толщины [2].
