Abstract

Graphical abstract: Highlights: An useful method to allow fast control of the stability of the forging process. An original method for reliable wear analysis of forging tools and forging defects. A practical solution not require interruption of production process. Research in area of scanner applications and validation in industrial process. Abstract: This article refers to the application of the 3D reverse scanning method for the purpose of analyzing the progressing wear of forging tools as well as detecting forging defects in selected hot die forging processes. By using the POLYWORKS software, the authors developed a numerical algorithm making it possible to determine the volume changes in selected areas of forgings periodically collected from the forging process, in comparison to a reference model. As a consequence of this, two parameters are determined: the positive volume – defining tool wear, and the negative volume – indicating a forging defect, e.g. underfill. Both of these parameters (positive and negative volume) are independent of one another. They can be used to determine the following characteristics: the tool wear curve and the curve indicating the possibility of a defect in forgings as well as disruptions of the production process. The presented approach may be a useful and effective tool which allows a quick assessment of the current tool status and forging quality (without the need for a significant interference in the production process). It may also serve as an instrument for the analysis of the stability and correctness of the production process.
