结论
数控机床加工中,子程序的广泛应用相对于循环指令编
程应用更简单,更容易保证零件的加工质量,提高生产效率。
但是在编制程序过程中需要合理运用绝对坐标编程指令 G90
与增量坐标编程指令 G91,切削用量,加工工艺等。合理应用
优化后的数控加工程序,可以更好的发挥数控机床的功能和
效率,更大的提高经济效益。

The Application of Sub Program in FANUC Series 21i CNC System
REN Rui ,WANG Gang- ming, YU Guo- qiang
(Faculty of Engineering, Ningbo University, Ningbo Zhejiang 315211, China)
Abstract: That the sub program is applied in the NC manufacture can simplify the program; guarantee the parts quality and increase produce
efficiency. FANUC Series 21i is the advanced NC system at present. The structure and range of the sub program was analyzed and the
attention question of the given example and using process is given. Also, the NC program was optimized which can improve the program
efficiency.
Key words : NC

Reform of Electric Control System on Hydraulic Experiment Platform
ZHANG Zhi- wei
(Guangdong Vocational College of Mechanical & Electrical Technology, Guangzhou 510515,China)
Abstract: The existing hydraulic test of the electrical control system were reformed according to the current hydraulic experimental technolo-
gy needs, joined the PLC control system, through the examples described the application in detail on the stage of PLC hydraulic experiments
and has made good effectiveness of teaching.
.Key word: programmable logic controller
;hydraulic experiment platform;electric control
接触器控制系统的可靠性差、控制不方便、响应慢等方面的不
足,而且还能够简化控制线路,缩小控制装置的体积,增强控
制系统的功能,实现了液压实验台的自动控制和多种复杂的
自动工作循环,同时还能把《液压传动》和《PLC 编程与控制》
两门课有机地结合起来,让学生能够切身地体会到同一专业
不同课程之间的联系,增强了学习兴趣,提高了学习效果。
