Dynamic Characteristic Analysis and Structural Modification of a 5-Axis Horizontal Machining Center Considering Joint Surface

Abstract

In order to make a 5-axis linkage horizontal machining center have better dynamic characteristics, considering the influence of joint surface, dynamic characteristic analysis is conducted to the machining tool. Based on finite element modal analysis results, the weak link is found and optimized. Through the finite element calculation and analysis, the structure rigidity obviously raises after optimization. This offers a new idea on how to improve the rigidity of complete machine of machining tool for later research.

Study on Post-processing and Nonlinear Error Compensation Technology for Dual 5-axis Linkage NC Machining Center

“…The composition of the various functional modules shown in Figure 2, main post structure parameters of machining center are shown in Table 1. Post-processing functions of the HTM50200 special-shaped stone NC machining center mainly include: (1)processing the CLSF file from different sources [5]; (2)post-processing parameter settings [6]; (3)post-processing algorithms judgment; (4)the tool length compensation [7]; (5)RTCP function [8]; (6)data conversion; (7)nonlinear error checking and processing [9]; (8)feed rate checking and planning [10]; (9)the function of data display and storage [11]; (10)other functions; of which, post-processing judgment function determine which kind of angle programming algorithm to adopt according to the quadrant in which the tool axis vector is located among the tool location information, while post-processing parameter setting initialize origin offset, tool offset and tool wear loss according to the actual situation of the processing center. The frame structure of the dedicated post-processing functions of processing center shown in Figure 3, Post-processing flow is shown in Figure 4.…”
