编号 南京航空航天大学金城学院 毕业设计 题 目 基于Labview的切削温度采集与分析系统的开发（题目：基于Labview的切削温度采集与析系统的分开发）labview，数cutting temperature acquisition and analysis system based on Labview Abstract Metal cutting when consumed by work, more than 90% is converted into heat cutting.Cutting heat will cause distortion, affect the machining accuracy and machining surface of burn, and even affect the parts wear resistance;Cutting heat will also accelerate the tool wear, shorten tool durability.Therefore, development of cutting temperature acquisition and analysis system, the real time and enhance the accuracy of temperature measurement, it is of great significance. First of all, the cutting temperature is developed in labview environment calibration and measurement software, the software includes data acquisition module, data analysis module, a half artificial thermocouple calibration module.Can realize the cutting temperature measurement data acquisition, processing, analysis, storage, and half artificial thermocouple calibration, etc. Second, the thesis discusses the half artificial thermocouple temperature measurement principle, the half artificial thermocouple calibration method is presented.And the cold end of thermocouple compensation, signal amplification, improves the accuracy of measurement. Finally the milling TC4 experiment was carried out, using this system the data, the data is analyzed, it is concluded that the influence of milling speed of milling temperature, verify the reliability of the system. Key Words：Virtual instrument, labview, data collection, measurement, and a half artificial thermocouple calibration  目录 摘 要 i Abstract ii 第一章 绪论 1 1.1 研究背景 1 1.2 研究现状 1 1.2.1 切削温度测量方法 1 1.2.2 热电偶信号的采集 3 1.3 虚拟仪器及laview简介 3 1.4 本课题拟开展的主要工作 4 第二章 数据采集处理系统的软件设计 6 2.1 软件总体设计 6 2.1.1 软件设计要求 6 2.1.2 系统软件框架 6 2.1.3 软件开发工具选择 7 2.2 软件模块设计 7 2.2.1 数据采集模块设计 7 2.2.2 数据分析模块设计 12 2.2.3 半人工热电偶标定模块设计 14 第三章 钛合金TC4材料铣削温度测量 18 3.1夹丝热电偶测温装置 18 3.2 实验设备 20 3.3 热电偶信号温度补偿 22 3.5 热
