刀具变形的在线散斑检测

On-line Measurement for Deformation of Tool Using Speckle Pattern Interferometry

散斑照相，防震要求低，光路简单，所需曝光时间短，符合连续激光对动态测量的要求。本文利用散斑照相法，测量了机床刀具的动态切削过程，并利用逐点分析和全场分析方法，分析了所拍摄的散斑图，得到了不同车速和不同切削用量条件下的位移场。

Speckle photography are introduced in this paper.The dynamic tooling process of the planer tool is measured by means of speckle photography.The displacement field and the strain field in different cutting velocity and in different cutting output is gained.The experiment demonstrates that the speckle pattern interferometry can be better used in dynamic measurement of planer tool.
