Abstract CNC technology is the technology of automatic CNC machinery with digital program control. With the rapid development of computers, automatic control technology, CNC technology has been widely used in CNC machine tools, robots and a variety of mechanical and electrical integration equipment. The interpolation calculation is the basic input data to the CNC system, the use of certain algorithms to calculate, according to the calculation results feed command issued to the corresponding coordinates.

Firstly, a basic introduction to the numerical control system interpolation principle, then an overview of Visual Basic. And then several interpolation analysis, including point by point comparison, digital integration, and data acquisition method, introduced three interpolation, linear and circular interpolation principle. And then again in Visual Basic for above software interface designed software program based on three interpolation principle, to debug the program, to enable them to achieve linear and circular interpolation, to achieve single-step interpolation, and shows calculation. Finally, the graduation project to make a summary and outlook.

The system by means of visualization of the image, given the dynamic interpolation demonstration process can help students be more intuitive understanding of the principles of CNC interpolation, NC teaching adjunct to, and the actual CNC machine the workpiece processing provides a theoretical basis.

Keywords: NC; interpolation; point by point comparison; digital integration; data collection method; in Visual Basic
