This has made five axis machining increasingly important. Due to higher degrees of freedom and better precision associated with five-axis machines, they are susceptible to impacts. Therefore, prior to commencement of the cutting process, five-axis machines must first undergo cutting simulations as a test for impacts. In light of this, this study proposes a five-axis machine model that is capable of motion simulation, and applies this model to the simulation of an NC tool path. A model of the five-axis machine is first developed in Pro/ENGINEER. Supporting tools are also developed using core programs including Pro/ENGINEER’s Pro Toolkit and MFC in Visual C++. With the supporting tools, users can understand the modelled behaviours of each axis in the machine. PowerMILL is used alongside the design workpiece model and NC program. Once information in both models is combined using NC cutting simulation in the software VERICUT, the five-axis cutting simulation can begin. In this way, model data for five-axis machines in all three software programs (Pro/ENGINEER, PowerMILL, and VERICUT) is integrated to provide users with an understanding of motion simulation of five-axis machines and the results of cutting simulation. The designed NC program facilitates easy and rapid delivery of the simulation results to users. Ching-An Lin 林清安 2012 學位論文 ; thesis 119 zh-TW |
