3、put on the NC process . the precision of the process and production effction largely depend on the effection and quality of the CNC programming procedure , which is the important part of NC technology and one of the key NC process technologies . There are so many NC millings (including machining cen
4、ter ) which have been used in mould industry , and most of the mould industries use the CAD/CAM software , so the manual programming and application of macro-program have less and less space , the reason of this is that workers dont have enough sight on the manual programming and are not familiar enough with the macro-program . In fact , manual programming is the foundation of automatic programming , at the same time , macro-program is the advanced form and essence of manual programming ,
