【摘要】：随着快速生长的国内制造业,数控加工已经成为市场竞争和企业生长的新亮点,先进的数控配置及技能正以昔所未有的速度,进入到我国种种制造企业中。但是随着当前数控机床的普遍利用,数控编程人员紧缺、数控手工编程效率低下等问题也日益凸显。近几十年来,随着PC技术、通信技术和网络技术的飞速发展,制造业也发生了巨大的变化,向着一体化、网络化的方向发展,将计算机应用于数控机床是肯定趋势。针对这些问题,如果依然采用传统的手工编程以及将程序手动输入数控机床的方式,不仅容易出错,效率也极其低下,不能保证企业的实际生产需要。如果您采用软件自动编程和实现数据传输方式,就可以显著提高编程效率和编程量,特别是在复杂的非圆形编程的轮廓中,可以体现其最大的优势。CAXA数控车其实是在传统加工和二维CAD图形软件上二次开发的新式CAD/CAM平台。CAXA数控车具备CAD软件强大的画图功能和完善的外置数据接口配置,能够经过DXF,IGES等数据接口实现和其它系统互换数据讯息,画出任何繁琐的轮廓图形。CAXA数控车还具有轨迹生成和后处理功能,在经过通用的后置处理模块进行处理后,使CAXA数控车可以生成满足各种不同系统机床的代码格式并输出,还可以利用软件本身模拟仿真对由CAD/CAM软件生成的加工程序进行机床加工过程的验证,验证程序正确与否。随着科技的持续发展,当今的制造业对产品的质量提出了更高的需求。因为有自动化水准高的数控机床拥有加工的高质量零件、产品质量牢固、高生产效率、便于产品的研发以及便于实现计算机辅助制造等特点而获得了长足的发展和广泛的使用。经过本论文的探寻和钻研,对CAXA数控车软件的实用性能、数据传输的时效性和稳定性进行了剖析,CAXA数控车软件选用RS-232C接口达成产品零件程序、机床参数等数据的高效率、高准确传输,解决了手工输入程序的低效,从而使数控车的数据传输问题得到有效地处置,有效地提高了编程正确率和加工效率,并能在学校和数控技能大赛中得到广泛应用。
[Abstract]:With the rapid growth of domestic manufacturing industry, NC machining has become a new bright spot of market competition and enterprise growth. Advanced NC configuration and skills are entering all kinds of manufacturing enterprises in our country at a speed not seen before.However, with the widespread use of CNC machine tools, the shortage of NC programmers and the inefficiency of NC manual programming are becoming increasingly prominent.In recent decades, with the rapid development of PC technology, communication technology and network technology, the manufacturing industry has also undergone tremendous changes, towards the direction of integration and networking. It is a positive trend to apply computers to CNC machine tools.In order to solve these problems, if the traditional manual programming and the manual input of the program into NC machine tools are still adopted, it is not only easy to make mistakes, but also extremely inefficient, which can not guarantee the actual production needs of enterprises.If you use automatic software programming and data transfer, you can significantly improve programming efficiency and amount of programming, especially in the contours of complex non-circular programmingCAXA NC car is a new CAD/CAM platform, which is developed on traditional machining and 2D CAD graphics software. CAXA NC vehicle has powerful drawing function of CAD software and perfect configuration of external data interface.It can exchange data information with other systems through data interface such as DXFFIGES, draw any complicated contour figure. CAXA NC car also has the function of track generation and post processing, after processing after the general post processing module,The CAXA NC car can generate and output the code format of different system machine tools, and can also use the software itself to simulate and simulate the machine tool machining process generated by CAD/CAM software, and verify whether the program is correct or not.With the sustainable development of science and technology, the manufacturing industry has put forward a higher demand for product quality.The CNC machine tool with high automation level has been developed and widely used because of its high quality parts, solid product quality, high production efficiency, easy product research and development and easy realization of computer-aided manufacturing.Through the exploration and research of this paper, the practical performance, the timeliness and stability of data transmission of CAXA NC vehicle software are analyzed. The RS-232C interface is used to achieve the high efficiency of product parts program, machine tool parameters and other data.High accurate transmission solves the low efficiency of manual input program, thus the problem of data transmission of NC car can be dealt with effectively, the correct rate of programming and processing efficiency are improved effectively, and it can be widely used in school and NC skill contest.
