A non-linear finite element model was developed for three dimensional soil cutting by tillage tools. A hyperbolic constitutive relation for soil was used in the model. Analysis was carried out to simulate soil cutting with rectangular flat and triangular tillage blades at different rake angles and with curved blades. Interface elements were used to model the adhesion and the friction between soil and blade surface.

In this paper, chatter in end milling machine tools is investigated using a Timoshenko beam model and finite element analysis. The model is developed for the cases where the slender machining cutters are flexible along the axial direction. A closed form solution for obtaining the stability lobes is derived assuming cutting forces as point loads applied to the end of the tool. It is shown that the stability lobes converge as the number of elements increase. The results indicate that using a single mass model used in the literature predict a more conservative chatter stability compared to the mo

Abstract:

Polycrystalline diamond (PCD), is a tool material and widely used in nonferrous metal processing due to its excellent properties, such as high hardness, high wear resistance, high thermal conductivity and low friction coefficient. Considering the friction between the cutter and the workpiece, the heat generated by the elastic-plastic deformation and the heat transfer between the cutter and the workpiece. The finite element analysis software ABAQUS was used to study the effect of different processing parameters on the temperature field distribution and cutting force of the cutter, in the case o

Abstract:

The finite element method was used to model chip formation in orthogonal metal cutting. Emphasis was given on analyzing the effect of important factors, such as plastic flow of the workpiece material, friction at the tool-workpiece interface, and wear of the tool, on the cutting process. To simulate separation of the chip from the workpiece, superposition of two nodes at each nodal location of a parting line of the initial mesh was imposed. According to the developed algorithm, the superimposed nodes were constrained to assume identical displacements, until approaching to a specified small dis

Abstract:

Due to raising ability of five-axis CNC machine tools to machine geometrically complex work pieces efficiently and with higher dimensional accuracy, it is necessary to research its mechanical eigenfrequence of mechanical transmission system. Considering the CNC machine tool’s work table runs slowly and has little damp, the system is considered as an invariable system and the whole system is nearly taken as structure in place of mechanism into account; The Finite Element method(FEM) in ANSYS software is presented in this paper to be used for the solution of the modal analysis of screw drive sys

Diffractive optical elements (DOE) can be used to simplify optical systems such as lightening its mass, reducing elements numbers and so on. Single-crystal diamond is considered as the preferred tool materials in ultra-precision and nanometer-scale cutting operation. Due to the well known and exceptional difficulty in shaping, the fabrication of diamond cutting tools requires special processing method. As a highly efficient and cost-effective solution, the mechanical lapping process has been extensively applied in tool-making industry. In this paper, the key enabling technologies to design and

The stiffness and damping of mechanical joint are modeled by the zero thickness joint interfaces theory. The method is applied to analyze the dynamic characteristic of the gantry frame in a five axis turning-milling compound CNC machine tool. The model test is carried out in the gantry frame, and the maximum error of the first sixth mode is 5.63%. The experimental and analysis result show the zeros thickness joint element can provide an effective method to model the machine joint and predict the dynamic characteristic of the assembled structure.
