Numerical control technology

NC refers to the automation of machine tools that are operated by abstract program.Compared with manual control, NC is more efficient and can machine more complicated shapes.This course briefly introduces history of NC, some basic codes(such as G codes and M codes), and steps of making numerical controlling programs.As for the make numerical controlling programs, first of analyse the workpiece and determine the machining path according to the sketch, then, select the proper turning tools according to their different functions, after that, determine the machining parameters, such as spindle speed, feed rate, depth of cutting, and so on.At last, make the program and try it
