PAW电弧增材制造过程温度与工艺参数监控系统研究

摘要近30年来，增材制造技术凭借其三维结构的快速和自由制造的优势飞速发展，在新产品开发和单件小批量制造中被广泛应用，越来越引人关注。对增材制造的成型特性控制研究逐渐成为热点。本文主要通过计算机软、硬件技术以及适当的数据处理方法的结合，采用霍尔电流电压采集模块，利用NI915无线采集卡和NI9191无线机箱，研究和设计了一套基于 labview 编程语言编写的增材制造过程温度及工艺参数监控系统。通过设计和编写labview程序，实现了等离子电弧热源增材制造过程的电流、电压和温度的数据采集，统计其幅值、均值，并显示和存储这些数据。经过分析得出电流增大时金属容易出现流淌，堆敷效果不理想。同时堆敷层数达到八九层时后，温度波形波峰较之前高且趋于稳定。87858

Title The study of monitoring and controlling system of temperature and process parameters for PAW Additive Manufacturing process

Abstract Over the past 30 years, with the rapid development of free three-dimensional structure, the rapid development of manufacturing technology has been widely used in the development of new products and small batch manufacturing, and has attracted more and more attention。 The forming characteristic control research of the increasing material manufacturing is gradually becoming a hot spot。 This paper mainly through computer software and hardware combination technology and appropriate data processing method, the use of Hall current and voltage acquisition module using NI915 and NI9191 wireless radio capture card chassis, a research and design based on labview programming language by material manufacturing process temperature and process parameter monitoring system。 Designing and writing labview program to achieve a plasma arc heat source material manufacturing process by current, voltage and temperature data collection, statistics amplitude, mean, and display and store the data。 Through the analysis, it is concluded that the metal is prone to flow when the current increases, and the effect is not ideal。 While the heap reaches cladding layers eighty-nine layer, the temperature wave crest than the previous high and stable。源-于,优Y尔-论,文.网wwW.yOueRw.com 原文+QQ752018,766
