目前,不少单位在应用上海技术物理研究所俄家齐所研制成功的利用日产fx-702 P型计算器编制数控线切割机程序的方法。笔者通过实践,确实感到此法通俗易懂,使繁复的编程过程大大简化,计算精度也有所提高,经济效益明显。适用于复旦型各种线切割机,包括无间隙补偿的机种。笔者所用DK6750型线切割机,带有间隙补偿和斜度补偿,在使用该编程方法过程中,尚感有可改进之处。因该方法所编程序为“三B”指令,缺少间隙和斜度补偿所必 At present, many units in the application of the Shanghai Institute of Technical Physics Russian home Qi developed by the successful use of Nissan fx-702 P-type calculator program of CNC wire cutting machine method. The author through practice, do feel this method is easy to understand, so that complex programming process greatly simplified, the calculation accuracy has also been increased, the obvious economic benefits. Fudan for a variety of wire cutting machine, including no gap compensation models. I used DK6750-type wire cutting machine, with gap compensation and slope compensation, in the use of the programming method, there is still room for improvement. Due to the method of programming for the “three B” instruction, the lack of clearance and slope compensation necessary
