随着我国经济的飞速发展,我国制造业装备的自动化水平在不断提高,数控机床的拥有量及在机床中所占的比重大幅度地增加。如何有效地发挥数控机床的使用效率、提高加工质量一直是人们追求的目标。在进行零件数控加工过程中,零件本身的可加工性和数控程序的质量是影响零件加工质量的关键因素。数控程序投入实际加工之前,都必须进行有效的检验。检验数控程序的方法主要有手工检验、试切检验、轨迹显示和计算机仿真等。其中计算机仿真是近年来发展较快,也是最行之有效的方法。数控车削是数控技术专业的核心课
With the rapid development of economy in our country, the level of automation of manufacturing equipment in our country keeps increasing. The possession of numerical control machine tools and the proportion of them in the machine tools have greatly increased. How to effectively use the efficiency of CNC machine tools to improve the quality of processing has always been the goal of people. During the part NC machining process, the part’s own machinability and the quality of NC program are the key factors affecting the quality of part machining. NC program into the actual processing, we must conduct an effective test. The main method of testing CNC program manual inspection, test cutting test, trajectory display and computer simulation. Among them, computer simulation has developed rapidly in recent years and is also the most effective method. CNC turning CNC technology is the core of professional courses
