基于能耗优化的机床换刀决策探讨(VB+Matlab)
摘 要
本课题来源于一个大型的工程应用项目,解决在机床能量消耗过程中海量数据的分析问题,本文通过数据分析技术将采样的数据进行存储并在分析时进行提取,以帮助我们找到影响机床能量的主要因素,以此来优化机床的结构,达到能源节约的目的。
本课题研究的主要内容包括数据采集,数据处理和数据分析。在数据采集中,需要采样大量的数据,然后进行数据分析,找到有用的数据,将这些数据进行处理,通过对这些数据的分析对比找出机床功率在不同情况下的耗能情况。
本课题的设计方案主要通过对机床电流的测量,运用计算机编写的程序将AD转换器所采得的数据存储在计算机上,运用MATLAB数据建模描图工具,将数据的曲线图描绘出来,找出不同情况下机床的能量消耗,最后通过决策分析得出机床在何种转速,何种换刀时间下,所消耗的能源最少。
由于我国是一个工业制造大国,机床的应用非常广泛,因此解决机床的优化设计和能源消耗是一个共性的科学问题,如果每台机床能节约一个百分点的能源,每年国家将节约上亿元的开销,因此本课题研究的成果将为国家带来巨大的经济利益和社会效益,显然本课题的研究具有重大的利益。

ABSTRACT
The issue stems from the Chong qing Institute of Technology instructor participation of a large-scale engineering projects, to solve the energy consumption of machine tools in the course of the massive data analysis, this paper, data mining technology will be sampling the data storage and analysis carried out in the extraction, to Help us to find a major impact on machine energy, machine tools in order to optimize the structure, to achieve energy conservation purposes.
The main topic of this content including data collection, data mining, data processing and data analysis. In data acquisition, it is necessary to sample a lot of data and data mining, to find useful information, these data will be processed through the comparative analysis of these data to identify machine power in different circumstances, the energy situation.
The topics mainly through the design of the current measurement machine, use a computer program written in AD converters will be collected by the data stored on computers, using MATLAB depiction map data modeling tools, data depicting the curve out to find out Under different circumstances machine energy consumption.
