Abstract: Traditional manufacturing and finishing operations of crystal products use intensive specialized labour resulting in high cycle times and production costs. It is intended to investigate the applicability of automated finishing technology, namely grinding in a CNC machining centre, with consideration of material’s characteristics and geometric variability to crystal processing. A case study will be presented, involving cutting tools development, cutting parameters optimization, CAM programming of machining strategies and toolpaths, product clamping systems and finally product machining and quality control that is being implemented at Vista Alegre Atlantis company.

Abstract: The method of laser inner engraving path generation and simulation for crystal glass is presented based on STL(Stereo Lithography) model. To generate the laser exposure points that are adaptive to the surface of model, the contour lines are obtained by cutting the STL model with unequal distance using a series of plans that are perpendicular to Z-axis. Then the contour lines are offset and scattered, and then the path is generated by sorting and connecting each discrete point in order. Simultaneously, simulation method of laser inner engraving for crystal glass is also proposed. The case studies show that the method can primely realize the engraving path generation and the simulation for the laser inner engraving of crystal glass, and that the system runs stably and reliably.
