The process of nc drilling and milling center, there are many influence factors in parts of the machining accuracy and productivity, especially complex parts processing, at the same time of guarantee machining accuracy, how is productivity? River machine tool plant, according to many years experience of numerical control drilling and milling machining center are using automatic programming can improve the utilization rate of machine tools, improve programming efficiency, guarantee quality, and the most programming. Therefore, CNC programming and parameter determination is very important.
Nc programming methods can be divided into two major categories of manual programming and automatic programming.
1, manual programming
Manual programming is written in artificial workpiece machining programs. Artifacts of geometric shape is simple, the program is not much, the coordinate calculation is more simple, the program is not too long, at this point, using manual ?
