【摘要】：基于椭圆划分和奇异点识别电火花放电点分布研究对可导电的金属进行精度高、效率高的切割。在以往的检测过程中忽略了一个重要的问题,就是对数据的优化。因为数据的研究直接导致了在对放电点位置检测以及评价的好坏。当在对数据进行研究的过程中,数据的结果直接影响了最后对WEDM检测评价的可靠以及规律性的研究。对所检测的出来的放电点去除噪点,排除不可能的因素从而使得检测的结果更精确评价系统。对WEDM放电点位置检测:对WEDM的加工方法进行比较,对WEDM放电点位置检测的不同模块、不同原理进行研究,选择合理高效的WEDM放电点位置检测方法应用到电火花线切割中,通过对WEDM放电点位置量化、优化以及评价模块的搭建,达到放电点检测的效果。分析对比WEDM放电点位置检测硬件系统的搭建,通过对LABVIEW可视化语言对整个WEDM放电点位置检测模块进行搭建;WEDM放电点位置检测实验研究。测试整个检测系统的可行性以及标定实验的设计,针对WEDM位置检测实验研究的在研究的过程中线材的长度进行优化,并且在确立实验的过程中提高对WEDM位置检测实验研究的准确性以及高效性,探究当WEDM加工过程中加工在乳化液DX-1介质中、在25ml/min蒸汽水雾介质中、在15ml/min超声水雾介质中和在大气介质中他们的放电点位置均匀性是如何进行变化的,同时去探究偏移量的增加和放电点均匀性之间规律以及工进给速度增加和均匀性之间的规律和联系。最终在微观的情况下得到不同状态下放电点分布的加工电参数和非电参数,得到相应最优的加工质量。
[Abstract]:Based on Elliptic Partition and singular Point recognition the Electrical Spark discharge Point Distribution (ESD) is used to cut conductive metals with high precision and efficiency. In the past, an important problem has been neglected in the detection process, that is, the optimization of data. Because the data research directly results in the detection and evaluation of the discharge point position. When the data are studied, the results of the data directly affect the reliability and regularity of the final evaluation of WEDM detection. The noise is removed from the detected discharge points and the impossible factors are eliminated to make the system more accurate. Position detection of WEDM discharge point: compare the machining methods of WEDM, study different modules and different principles of WEDM discharge point position detection, select reasonable and efficient WEDM discharge point position detection method to be applied to WEDM. Through quantization, optimization and evaluation of WEDM discharge point position, the effect of discharge point detection is achieved. This paper analyzes and compares the construction of WEDM discharge point position detection hardware system, builds the whole WEDM discharge point position detection module by LABVIEW visual language, and studies the experimental research of WEDM discharge point position detection. The feasibility of testing the whole detection system and the design of calibration experiment are tested. The length of wire rod is optimized in the course of the research of WEDM position detection experiment. And in the process of establishing the experiment, the accuracy and efficiency of the experimental research on the WEDM position detection are improved. It is explored that when the WEDM is processed in the emulsion DX-1 medium and in the 25ml/min steam water mist medium, How the uniformity of their discharge points changes in 15ml/min ultrasonic water mist media and in atmospheric media, At the same time, the law and relation between the increase of offset and the uniformity of discharge point and the increase of feed speed and uniformity are explored. Finally, the electrical and non-electrical parameters of the discharge point distribution in different states are obtained under the micro condition, and the corresponding optimal machining quality is obtained.
