Research for Auto-identification and Removal Approach Built-up edge in Image monitoring Approach for Tool wear 刀具磨损图像监测法中的积屑瘤自动识别与去除方法的研究
By electronic microscope analysis, it is found that there is a certain amount of second dispersed phase in the martensite matrix which is the metallurgical factor of forming built-up edge. 通过电镜分析,发现在马氏体基体上有一定数量的弥散的第二相存在是引起积屑瘤产生的冶金因素。
The investigation of using the optical fiber transducer in on-line monitoring of the chatter, the tool breakage, and the formation of built-up edge is made, and the results show that the transducer is available in monitoring the abnormal cutting states. 利用光纤传感器对在线检测颤振、刀具破损和积屑瘤的形成进行了探讨,研究结果证明光纤传感器在线检测异常切削状态是可行的。
The essential of urban built-up area expansion is the process that human being constantly adjust and arrange land use in the urban edge to satisfy the development requirements of social economy. 城市建成区扩展的实质是人类为满足社会经济的发展需要,不断地调整、配置城市边缘区各类土地利用的过程。
Then, the relationships between the built-up edge and the cutting speed, the undeformed chip thickness, the width of the uncut chip, and, lastly the rake angle were found. 从而获得了:切削速度、切削厚度、切削宽度和刀具前角对积屑瘤影响的规律。
Experiment has been done in order to measure milling force, by analyzing cutting-force fluctuating rule so as to deduce whether exist built-up edge in the machining process or not, validate the rationality of milling style; 实验测定铣削力,通过分析铣削力的变化,来推测加工过程中是否存在切屑瘤,验证铣削方式的合理性;
Cutting test results show that the measuring system developed is capable of identifying the influences of the built-up edge on cutting tools, of the selfexcited vibration in the cutting process and of the tool wear on the machined surface morphology. 切削试验表明,该装置能够在线识别刀具上的积屑瘤、切削过程中的颤振和刀具磨损对加工表面形貌的影响。
The bigger built-up edge left on the machined surface is the greater dynamic component of cutting force, and the higher the height of scaling. 切削力动态分量越大,相应的鳞剌高度越高。
