Research And Development On Cutting Simulation System Of NC Machining Center

The high speed development of science and technology has accelerated the change of manufacture. The numerical control technique is becoming the kernel technique of modern manufacture technology. Virtual manufacture technology as necessary complementarities of generalize and development in NC technology, which becomes a research goal, which Scientific researcher pay attention to it. In this paper, based on the analyses and investigation of current achievements of vertical milling center, further research has been done in the following aspects.1 The virtual NC system is designed, Disassemble machining center into parts, accessory and components by hierarchical modeling function. These three parts compose the three levels assembling tree of the machine tools, and in this way, the geometry modeling of vertical milling center is founded. According to the structure construct the geometric model of Automatic Tools Changer and ATC control system.2 The analysis processing method and the translation principle of the NC numerical control code and according to the numerical control system's standard to design the virtual numerical control system compilerIs studied.3 Based on analyzing the character of tools and parts , uses the data-base knowledge of Microsoft Active Data Objects(ADO) , This module can realized the management function for cutting tools and parts, it can accomplish the lookup ,editing, adding and deleting4 Innovation (Z-Quadtrees) algorithm is propose innovatively to eliminate material of simulation parts, and thesimulation model of parts and the cutting tool is established.
