数控锻铜浮雕加工关键技术的研究
|
摘要
针对手工锻铜存在的缺陷和不足,提出了一种数控锻铜浮雕加工方法。采用Art CAM建立浮雕模型并保存模型的三维数据。同时根据二维图像,生成数控铣刀的走刀路线,在铜板上錾出图像的几何轮廓。结合浮雕模型数据,利用设计的机械锻打设备,按照由外轮廓到铜板中心的锻打方向锻敲铜板。锻打过程中,通过高速高精度激光测距传感器实现闭环反馈回路控制机械锻打设备的锻打深度。实验结果表明:该方法有效降低了人工劳动强度,很大程度上缩短了铜浮雕的加工时间。
To overcome the defects and deficiencies in hand-hammered on copper,a machining method based on numerical control technology was proposed. Art CAM was used to build a three-dimensional relief model. The three-dimensional data of relief was saved which was processed basing on ductility coefficient of copper. At the same time,the geometric contours was carved on copper using CNC milling cutter. The tool path of CNC milling cutter was designed according to two-dimensional image. Combined the three-dimensional data with the mechanical forging equipment,the copper was struck from the border to center. During the striking,the forging depth was controlled by the feedback data of laser distance measuring sensor which is high speed and high precision. Experimental results show that this method reduces the labor intensity effectively and shorten the processing time of copper relief greatly.
