| 摘 要： | 硬质合金刀具刃口是影响精密加工表面质量以及表面微观几何形貌的重要因素。针对目前测量过程中出现的问题,提出利用DLP技术来测量刀具刃口的三维形貌。其原理是用计算机产生正弦投影条纹,经数字投影仪投射到物体表面,条纹经物体表面调制产生变形,用CCD摄像机将变形条纹拍摄下来。再利用计算机进行相位场提取、相位去包裹,得到绝对相位值。最后经系统标定、坐标变换可得物体表面的三维数据基于数字条纹投射的光学3D传感器,这样能够很好很快地提取刀具刃口的三维形貌。

| Abstract: | Carbide cutting edge is an important factor to affect the precision machined surface quality and surface mi- cro - topography. Due to the problems of current measurement process, the aticle uses DLP technology to measure the three - dimensional morphology of the cutting edge, based on optical 3 D sensor of digital fringe projection,picking up three - di- mensional morphology of the cutting edge well and quickly. |
