The present article deals with the possibility of using the reverse engineering method for the production of prototype molds by Patternless
process technology. Article describes method how to obtain virtual model by using a 3D scanner. Article also explains principle of the
Patternless process technology, which is based on the milling mold cavity using CNC machining equipment. The aim of the research is the
use of advanced technologies that speed up and facilitate the process of production prototype mold. The practical result of the presented
experiment is bronze casting, which serves as a foot rest bracket on historic bike.
The paper deals with evaluation of a 3D scanning method elaborated by the authors, by applying it to the analysis of the wear of forging tools. The 3D scanning method in the first place consists in the application of scanning to the analysis of changes in geometry of a forging tool by way of comparing the images of a worn tool with a CAD model or an image of a new tool. The method was evaluated in the context of the important measurement problems resulting from the extreme conditions present during the industrial hot forging processes. The method was used to evaluate wear of tools with an increasing wear degree, which made it possible to determine the wear characteristics in a function of the number of produced forgings. The following stage was the use it for a direct control of the quality and geometry changes of forging tools (without their disassembly) by way of a direct measurement of the geometry of periodically collected forgings (indirect method based on forgings). The final part of the study points to the advantages and disadvantages of the elaborated method as well as the potential directions of its further development.
