Abstract
The present invention discloses a system for monitoring dynamic stability of micro machine is provided in this invention, wherein an image-capturing device and an analytic device are included. The image-capturing device captures an image on a surface of a work piece milled by the micro machine. The analytic device comprises an image input interface, means for gray-scaling an image, means for analyzing abnormal gray-scaled value of the gray-scaled image, and means for analyzing numbers of veins of the gray-scaled image. This invention also provides a method for monitoring dynamic stability of micro machine.
Claims20
A system for monitoring dynamic stability of a micro machine, comprising:
- an image-capturing device for capturing images of a micro tool of the micro machine processing on a workpiece;
- and
- an analysis device, comprising:
- an image input interface for receiving the images captured by said image-capturing device;
- means for transforming the images into gray-level to gray-levelized images;
- means for analyzing abnormal gray-level ratio of the gray-levelized images, comprising:
- hues exchanging unit for exchanging dark and bright hues of the gray-levelized images into exchanged gray-levelized images;
- image-carving unit for capturing bright areas of the exchange gray-levelized images;
- calculating abnormal gray-level exponential unit for calculating exponential of abnormal gray-level to all pixels of the exchanged ray-levelized images;
- and
- calculating abnormal gray-level ratio unit for calculating ratio of abnormal gray-level to pixels of the exchanged gray-levelized images;
- and
- means for calculating vein quantity of the gray-levelized images.
A method for detecting dynamic stability of a micro machine, comprising:
- capturing an image of a workpiece surface with milled vein, wherein the wrokpiece surface is milled by a micro tool of the micro machine;
- transforming the image into gray-level;
- exchanging hues of the gray-level image;
- calculating a ratio of abnormal gray-level to the gray-level image;
- calculating vein numbers of the gray-level image;
- and
- analyzing feed/tooth value of the micro machine.
