Sažetak
In the turning process, clamping the workpiece in the chuck often leads to deformation, which can be both elastic and plastic. These deformations directly affect dimensional accuracy, consequently reducing the overall quality and reliability of the final products and potentially leading to rejections and increased production costs. The issue becomes even more critical when machining precision tool components intended for the production of glass packaging, where high accuracy is essential for functionality and durability. This paper thoroughly examines this challenge through advanced numerical simulations conducted using the finite element method (FEM). Using the Hexagon Marc/Mentat software environment, a detailed analysis was performed to investigate the influence of using different numbers of chuck jaws on the deformation, shape, and stress distribution of the workpiece. Based on the simulation results, the paper provides clear recommendations for an optimized clamping configuration, specifying the ideal number of chuck jaws to minimize deformation and enhance final part accuracy.
