Machining with five-axis equipment can offer manufactures many advantages, including dramatically reduced setup times, lower costs per part, more accurate machining and improved part quality. While in five-axis machining, the tool axis changes frequently, even the most experienced engineers are difficult to judge the correctness of its tool path. So in this paper, taking five-axis machine tools as the prototype, the process of building NC simulation platform was introduced by using simulation software VERICUT. After that, it introduced simulation operations, verifying the simulation platform and data simulation function. Finally, the correctness of the simulation was verified by machining experiments. Researching CNC machining process on the VERICUT platform, the research results were used in five-axis machining simulation of integrated impeller and it improved both the process capacity and efficiency of the integrated impeller greatly. This method obtained in this paper could eliminate the colliding and interference phenomenon during test cut, reduce costs, improve the efficiency of programming and shorten the manufacturing period.

Sculpted surfaces are widely used in engineering applications in industries like aerospace, automotive and medical. Commonly, these types of surfaces are manufactured by the process of 5-axis CNC machining. 5-axis machining improves the effectiveness and reduction in machining times compared to the 3-axis process, but also increases the complexity of the operations. This paper presents a four-axis toolpath generation gouging free methodology as an alternative to the five-axis machining to reduce the complexity of the process, maintaining similar benefits respect to conventional three-axis machining. Rolling ball method is first applied to compute the most suitable tool for the surface and prevent gouging. A process procedure is the carried out to optimize the tool fixed position and compute tool location at each cutter contact point of the surface. The results show the effectiveness of the method in terms of reducing machining time and maintaining similar surface finishing compared with three-axis machining. The method can be used as a cost-effective option for multi-axis machining.

Deviation Method

Five-axis computer numerical control (CNC) machining is characterized with a multitude of errors. Among them an important component comes from the computer-aided manufacturing software known as the geometry-based errors. A new and accurate method to determine these errors is presented in this paper as opposed to the conventional chordal deviation method. The present method allows establishing the exact linearly interpolated tool positions between two cutter contact points on a given tool path, based on the inverse kinematics analysis of the machine tool. A generic procedure has been developed to ensure wide applicability of the proposed method. Analytical derivation of the geometry-based errors provides insights regarding the origin of these errors and their affecting parameters. Due to the highly non-linear characteristics of the problem, analytical solutions can only be obtained for simple surface geometry. Numerical computation is able to determine the errors for general surface shapes but it would be difficult to uncover further insightful information from the calculated error values. Besides the local surface geometry, the configuration of the kinematic chain of the CNC machine has been found to be the primary factor controlling the resulting value and type of the geometry-based errors. Implementations with a typical complex free-form surface demonstrated that the conventional chordal deviation method was not reliable and could significantly underestimate the geometry-based errors.
