CNC Turning Precision And Accuracy Of Prediction Modeling Analysis

In recent years, with the needs of the community to personalized, diversified development, machinery manufacturing industry is experiencing a high volume of production to a multi-species, variable-volume production development. Precision, flexibility, networking, virtualization, intelligent, clean, integration, globalization is the development of advanced manufacturing technologies become mainstream. Compared to traditional processing technology, CNC machine tool technology with a high precision, high efficiency, can a machine and general machine tools can be difficult to complete or can not complete processing of complex parts processing characteristics of the curve to solve the problem for most parts machining .However, in actual production, because production conditions, parameters such as impact indicators, are often not the desired effect. The purpose of precision, is to study how to control a variety of errors within the specified tolerance range, precision control of various factors on the impact of the law, and thus find ways to reduce processing errors, improve the precision of the measures.This article focuses on analysis of the process by cutting force and cutting heat system changes caused by the impact of errors on the precision of the cutting force, cutting heat and other influencing factors, while modeling, so that all the causes of the error to establish their own coordinate system , dealt with separately, and then all the errors by Coordinate transformation coordinates into a unified process, the establishment of an integrated model prediction. Features for CNC turning, CNC turning test designed for processing, the radial dimensional accuracy for the study, completed a verification of the accuracy of forecasting models, while changing the cutting elements of the data collection process, a single factor and orthogonal binding mode analysis , has been turning the radial size range of the experimental conditions change the distribution and accuracy of processing parameters on the machining accuracy of the relationship between the level of changes in factors affecting the precision of the significant difference, and get the best combination of processing conditions program. Changing the process parameters to validate the case of processing, analysis and forecast model prediction.This paper, a comprehensive predictive model accuracy, so that only single or a few factors to consider the model to predict poor results of the case progress, guide the operator personnel in a timely manner to adjust the cutting parameters with help and guidance role, but also for the future of CNC machining parameters indicators development and actual production and processing to provide a theoretical and practical basis.
