Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] see figure 1 , the figure shows the UG-based five-axis CNC machine tool modeling and virtual assembly method of the present invention, in the present embodiment, using UG NX4.0 software, the present invention includes the following steps:

[0026] Step 1 of three-dimensional modeling of a single part is to draw a three-dimensional figure according to the actual size of the part of the five-axis CNC machine tool. This step includes the self-made parts modeling step and the standard parts modeling step, wherein:

[0027] The self-made component modeling steps are used for modeling based on the UG platform, through display modeling, parametric modeling and constraint-based modeling. The combination of these three modeling methods is composite modeling. Features are:

[0028] (1) Provide more flexibility in the design process.

[0029] (2) Establish a fully correlated...

Abstract

The invention discloses a method for modeling and virtually assembling a five-axle number control machine tool based on UG. The method comprises the following steps: three-dimension modeling of a single part, i.e. drawing a three-dimensional figure according to the actual sizes of parts of a five-axle number control machine tool; and assembly step, i.e. after the three-dimension modeling is performed to all the parts of the five-axle number control machine tool, virtually assembling by using a UG three-dimensional platform, and respectively calling in the environment required for assembly and the parts required for assembly under the condition of assembly drawing, performing position direction constraint to all the parts through constraint conditions, then virtually assembling all the parts of the five-axle number control machine tool, and finally, overall assembling the machine tool. The invention can perform analog simulation to the five-axle number control machine tool, enables a designer to discover the potential problems in time through modeling and virtual simulation, reduces the manufacturing cost and enhances the manufacturing accuracy.

Description

technical field [0001] The invention relates to a method for modeling and virtual assembly of a five-axis numerical control machine tool, in particular to a method for modeling and virtual assembly of a five-axis numerical control machine tool based on UG. technical background [0002] The five-axis CNC machine tool is based on the existing machining center, adding A-axis and C-axis rotation, CNC equipment with five-axis processing capabilities. The most effective processing surface of the vertical machining center (three-axis) is only the top surface of the workpiece, and the horizontal machining center can only process the four sides of the workpiece with the help of the rotary table. At present, high-end machining centers are developing in the direction of five-axis control. For example, if it is equipped with a high-end CNC system with five-axis linkage, it can also process complex spatial surfaces with high precision. [0003] Many foreign companies attach great impor...
