With the deepening of globalization, China has become the world's factory for its special advantages to provide various types of products around the world. The manufacturing industry in which you play the most important role. CNC machine tool has a high-precision, high-efficiency machining complex surfaces, and can improve working conditions and reduce labor intensity, etc., is becoming increasingly popular in the manufacturing and processing industry. Types of CNC machine tools are also increasingly diverse, covering almost all fields of processing. Precision parts distribution system error statistical methods and conclusions relative to traditional machining parts with, CNC machined under the conditions of the rarely been studied, there is no off-the-shelf precision distribution theory to provide reference and basis for the production of CNC machining. The subject is based on the status quo. The three factors and three levels orthogonal test MKS1320 CNC cylindrical grinder, the grinding depth, workpiece speed and vertical mill different level combinations under the conditions of axial feed speeds of these three factors, the machining accuracy of the data of the test pieces , including machining errors and surface quality precision two categories. Processing errors into the size of the error, and the shape and position error, surface quality to consider changes in the surface roughness and the grinding surface microstructure. The size of the error to consider the error of the diameter of the cylindrical surface, the shape and position errors consider grinding test piece cylindrical roundness, concentricity and eccentric circle profile error. Diameter obtained by digital micrometer measurements, intuitive analysis of the relationship between the diameter and factors, the primary and secondary factors and the best combination of factors; distribution analysis statistics diameter distribution under the conditions of different combinations of factors, analysis the error causes. Dividing head clamping test pieces indexing, digital dial gauge to measure the outer contour data by Matlab language to draw the outline of cylindrical cross-section to be tested, the roundness of the least squares method, derived test pieces round , concentricity and eccentric circle outline of the statistical distribution of the three form and position errors and a combination of factors on the distribution, and analysis of the distribution of causes. TR210 roughness detected specimen surface roughness, the intuitive analysis of the roughness and the relationship of various factors, primary and secondary factors and the best combination of factors; statistical distribution of roughness under the influence of various factors. Coordinate the profiler observations grinding surface of different three-dimensional morphology, analysis of the morphology difference causes, and parts of the surface strength, surface hardness, wear resistance, and other key aspects of the impact. The grinding tests flutter analysis, use, and the corresponding surface of the three-dimensional morphology coordinate profilometer capture, then the phenomenon generated by the grinding mechanism.
