This paper presents a postprocessor for five-axis milling machine that capable of converting CL (cutter location) data to machine control data (NC program). The proposed postprocessor method is based on inverse kinematics transformation and postprocessor module is programmed in Visual Basic language. The Deckel Maho DMU 50 eVoluion five-axis machine with two rotary axes (B and C) on the table is modeled and verified in software VERICUT® to validate the NC data generated by proposed postprocessor.

Abstract Owing to the existence of the cone angle, the size of a conical counter-rotating twin screw continuously changes along the axis, so it is not easy to model using SolidWorks. In this study, the parametric design of the modeling process is completed based on the Visual Basic language and a program-driven method. Finally, the SolidWorks program plug-in and user interface are developed to complete the automatic generation of the three-dimensional model of a conical counter-rotating twin screw.

This paper deals with the development of a practical postprocessor for 5-axis machine tools. Recently, special 5-axis machine tools with non-orthogonal rotary axes as well as typical 5-axis machine tools with orthogonal rotary axes have been introduced. In the present work, the general equations of NC data for 5-axis configurations with non-orthogonal rotary axes are exactly expressed by the inverse kinematics, and a Windows-based postprocessor written in Visual Basic was developed according to the proposed algorithm. The developed postprocessor is a general system suitable for all kinds of 5-axis machine tools not only with orthogonal rotary axes but also with non-orthogonal rotary axes, thereby expanding the range of application of the developed postprocessor. In addition, through implementation of the developed postprocessor and verification by a cutting simulation and machining experiment, the effectiveness of the proposed algorithm was confirmed. Compatibility was improved by allowing exchange of data formats such as RTCP controlled NC data, Vector post NC data, and POF CL data, and convenience was increased by adding the function of work-piece origin offset. Consequently, a practical post-processor for 5-axis machining has been developed.

Geometric deviation, defined as the distance between the designed surface and the machined surface, is an important component of machining errors in five-axis flank milling of the S-shaped test piece. Since the interpolated toolpath in practical machining process is the approximation of the theoretical toolpath, the geometric deviation caused by the interpolated toolpath appears. To overcome this problem, a novel geometric deviation reduction method is suggested in this study. First, the features of the S-shaped test piece are analyzed. Second, the theoretical toolpath is generated according to the designed surface and the cutter location data is obtained by discretizing the theoretical toolpath. The linear interpolation of the cutter location data is carried out to obtain the interpolated toolpath. Then, the geometric deviation is modeled by calculating the Hausdorff distance between the tool axis trajectory surface based on the interpolated toolpath and the offset surface of the designed surface. Finally, the geometric deviation is reduced by optimizing the cutter location data without inserting more cutter location points. The machining experiment is conducted to verify the effectiveness of the proposed method. The experimental results agree with the simulation results, and both of them indicate the geometric deviation on the machined surface reduces after optimization.

Postprocess capable of converting the cutter location data to machine control data is an important interface between the NC programming design and manufacture.Due to the fact that current research on multi-axis postprocess methods mostly deals with machine tool configurations whose linear and rotational movements are orthogonal, an efficient postprocess algorithm for the five-axis machine with a tilting head is presented in this paper.DMU 80P which is a five-axis machine with a tilting head is selected as an example.Its mechanism model is proposed in this paper according to the mechanism theory.The kinematics model is established using coordinate transformation,and the solution of this model is discussed.Based on these,a window-based post-processor with multi-choice function was developed by VS2010 language.Through the verification by the commercial solid cutting software VERICUT,the feasibility of the algorithm proposed is demonstrated.At last,a real impeller cutting experiment has been conducted and the result further verifies the correctness of the algorithm.
