Modeling Analysis And Study On Milling Parameter And Power In Small And Medium-Sized Nc Milling Machine

The cutting parameter is key factor of process on NC milling machine, It depends on related information resources, such as process information,NC machine equipment,NC cutting tools,workpiece material. The choice of cutting parameter depends on the cutting parameter handbook and other datas in the past in addition to by means of experience. Mosting looking up handbook is extensively applied to production becuase of its simple, but there are something different with a lot of using of NC machine. Based on these difference, this paper built a function model between cutting parameter and cutting power by measuring the changing cutting power which is caused by the change of cutting power. It is guiding significance to choose the cutting paremeter on NC milling machine processing.In this periment, there are four function model between single cutting parameter and cutting power with the change of single cutting parameter , beginning with the choice of single cutting parameter by handbook or experience. Then, the function model between four cutting parameter and cutting power can be created, according to the changed power with the change of cutting parameter which is selected based on those four function.The trial is designed with orthoplan in this paper. After five-factor-four-level orhhogonal table used for arranging trail, the paper adopted linear regression and no-linear regression analysis to finish data processing, then regression equation can be bulit. Through correlation coefficient test and analysis of variance, the paper proved the significence of regression equation.The reliability of function model bulid in this paper is beyond ninty-nine percent. The cutting parameter based on function model bulit in this paper had the higher credibility for low-power NC milling machine and ordinary workpiece material. The research of this experiment is a grope for cutting parameter of NC milling.
