  • Patent number: 8885038
    Abstract: Provided is an apparatus and a method thereof which can detect a displacement amount of a cutting tool with respect to a workpiece with high accuracy and can correct a processing position with high accuracy. Accordingly, a turret gauge 46 is comprised of an invar body 47 and a gauge main body 48 with a different thermal expansion coefficient. A point A of the gauge main body 48 and a leading edge 47A of the invar body are imaged in a state of viewing the whole thereof at a time of an initialization and a calibration cycle (CS), and a temperature of the gauge main body 48 is detected by comparing each image data. Furthermore, the length between the point A and a point B of the gauge main body 48 at the time of the CS is obtained based on the image data. The actual length is compared with a theoretical length between the point A and the point B at a temperature of the gauge main body 48 at the time of the CS, and consideration is given to the comparison.

  • Publication number: 20060174480
    Abstract: An inspection apparatus for mounted electronic components in a component mounting apparatus is provided with camera means capable of placing within its sight a whole printed board. The camera means picks up a first image for the whole printed board which does not have any electronic component mounted thereon. Those but some left of the electronic components to be mounted are then mounted on the printed board. The camera means then picks up a second image for the whole printed board on which those but some left of the electronic components have been mounted.
