Image processing for machine vision measurement of hot formed parts

Fast dimensional measurement method and experiment of the forgings under high temperature

“…Some approaches for acquiring clear images of hot forgings have been studied. Dworkin and Nye (2006) acquired a clear infrared image with infrared filter. However a lot of useful information for calculating the dimensions of hot forgings has also been filtered out.…”

An improved image acquiring method for machine vision measurement of hot formed parts

“…Many approaches for acquiring images of hot parts have been studied. Dworkin and Nye (2006) developed a method that enabled the use of CCD cameras to get images of hot parts. As lenses of CCD focus differently according to different light wavelength, the infrared light will be unfocused when viewing a hot object with a lens focused for visible light.…”

Research on some basic deformations in free forging with robot and servo-press

“…However, the anisotropy of metal materials was not taken into consideration in predicting the width spread in these reports. Dworkin and Nye (2006) designed a manipulator to accommodate the movements of material.…”
