坐标偏移在数控铣削加工中的应用研究

Applied Research on Coordinate Shift Instruction in NC Milling Machining

对于部分特殊结构的零件,合理利用数控代码中的坐标偏移指令,使所编的程序得到明显简化,可以方便快捷地完成零件的铣削加工。以FANUC数控系统为例,着重介绍了G51.1、G52、G68指令的格式、应用技巧及注意事项,并结合实例详细叙述了这些指令在数控铣削编程中的应用。

According to the parts of some special structure, reasonable use of coordinate shift instruction of NC code, so that the compiled program has been significantly ,simplified, it can complete the milling machining of the parts easily and quickly. The paper takes the FANUC NC system as example, introduces the instruction format, application skills and the matters needing attention of GS1.1, G52, G68, and finally explains that how to use these instructions in NC milling programming.
