The development of an automatic scanning path generation method for the spinneret test

An automatic scanning path generation method is developed. The method is based on a 3-axis automatic inspection system which is used to detect the clearance ratio of spinneret plate. The user can rely on this method to automatically generate the scanning path for an unknown spinneret plate in the spinneret test. Then the scanning path can be learned by the inspection system and repeated it for other the same spinneret. Two type spinnerets are introduced in this paper to describe the automatic scanning path generation method. In this paper, the 3-axis automatic inspection system includes a 3-axes motorized linear stage, a telcentric lens, a top light source, a bottom light source, 1 CCD camera and a controlled PC.
