A new approach of modeling micromachining parts with a shaped generatrix by image processing of tool's cutting surface

SPIE/COS Photonics Asia, 2022
A method for microprocessing products with a shaped generatrix by remote the product from the image is proposed, which provides an increase in productivity without loss of quality. The method allows you to recreate an object based on image reconstruction
