Real Time Chatter Vibration Control System in High Speed Milling

引用

材料科学与工程（中英文A版） 2015年第5期5卷 221-229页

作者： Hyeok Kim Mun-Ho cho Jun-Yeong Koo Jong-Whan Lee jeong-Suk Kim School of Mechanical Engineering Pusan National University Busan 609-735 Republic of Korea Department of Mechtronics Engineering Korea Aviation Polytechnic Busan 616-741 Republic of Korea Department of Mechanical Engineering Pusan National University ERC/NSDM Busan 609-735 Republic of Korea

This paper presents the chatter vibration avoidance method in high speed milling. Chatter vibrations have a bad influence on surface integrity and tool life. So how to get the cutting conditions without chatter vibration is very important. In order to get stable cutting condition, too many parameters are required. So this paper focuses on simplification and real-time control of chatter avoidance program. The developed method uses only microphone signal for chatter vibration sensing. The measuring signal is analyzed by FFT (Fast Fourier transform) method to get whether or not the chatter vibration is generated on cutting condition. If chatter vibration occurs, the developed program suggests stable cutting speed in real time with tool teeth number, damping ratio and chatter frequency. This suggested that the program reliability is confirmed by dynamic cutting forces and surface profiles.

背景当药物总量固定时，局麻药的容积或浓度改变是否会对骶管麻醉的扩散平面及镇痛效果产生影响尚不清楚。方法本研究采用前瞻、随机、观测者盲法实施。年龄为1—5岁的小儿给予预先配置、剂量为2．25mg＆g的罗哌卡因。其中一组给予1．0ml／kg浓度为0．225％（小容量／高浓度[10wvolume／highconcentration，LVHC]，n=37）的药物，男一组给予1．5ml／kg浓度为0．15％（大容量“氐浓度[highvolume／lowconcentration，HVLC]，n=36）的药物。两种溶液中均舍有不透放射线的染料.结果HVLC组扩散平面的中位数及范围（T6，T3-II）明显高于LVHC组（T11，T8—12）（经X线透视证实）。、两组在恢复时间、术后疼痛评分和副作用方面没有显著性差异。停药舌，HVLC组与LVHC组相比，需要给予对乙酰氡基酚来缓解疼楠的儿重更少（50．0％vs75．7％）。HVLC组患儿首次需要口眼对乙酰氧基酚的时间明显晚干LVHC组（363．0分钟VS554．5分钟）．结论我们证实（经X线透视检查）以1ml／kg罗哌卡因施行骶管麻醉时扩散平面可达T11，而采用1．5ml／kg时则可扩散至T6水平。日间小儿睾丸固定术麻醉中，如果药物总量固定，大容量稀释的罗哌卡因（0．15％）相对小容量高浓度罗哐卡因（0．225％）具有更好的镇痛效果和更长的作用时间。罗哌卡因的麻醉扩散平面与首次口服对乙酰氯基酚的时间显著相关。

朝鲜王朝末期学者茶山丁若镛认为,《大学》以诚意为中心,强调孝、弟、慈的实践,《中庸》则通过认识“上帝”和鬼神的慎独,将重点放在诚的体现上。根据茶山的观点,《大学》的明德不是本然之性,而是通过行动才具备的,因此实践孝、弟、慈的内在依据被弱化,《中庸》虽然强化了“上帝”(鬼神)对人类的监督,但是在现实中诚的体现并不明确。茶山将这两本书联系起来,解决了各自存在的问题,“诚”就是解决问题的关键。因此,只有同时研究茶山关于《大学》和《中庸》的相关观点,才能整理出其贯通形上和形下的诚论,并掌握其对《大学》《中庸》的理解的核心。具体来说,通过慎独认识“上帝”的监督而“戒慎恐惧”就是《中庸》的“诚”,将这种恐惧之心运用到人事上,体现孝、弟、慈的实践是《大学》的诚意。茶山把“格物致知”单独安排,主张“格致六条说”,如果从“诚意”到“平天下”体现“诚”,这就是人伦之道所追求的“止于至善”,《中庸》所说的“至诚”。
