Abstract
This paper introduces the Technology and programming of precision and complex part, the main steps included the analysis the pattern of every parts, determine the processing process.Calculate the trail of the knife, obtain the cutter location data of the knife. Compose the NC program. Manufacture the controlled medium. Proofread the program and the first trial cut. In order to ensure the optimal solution, the experiment are carried out for NC process analysis. The main tool used to is NC milling machine and center of machining, the NC milling machine is one of the most important equipment of modern CNC technology. The development of the NC milling machine is the result of the development of IT and MT. The NC technology is the important part of modern manufacturing industry. P roe is based on the modern manufacturing technology. This paper introduces the characteristic of the NC machine machining process analysis and the general steps of NC programming.And the method of processing technology and programming of NC is introduced through examples.
