INCREASING THE EFFICIENCY OF EXTERNAL TURNING BY USING THE MULTIPLE LAYER CONSTRUCTION OF THE CUTTING TOOL HOLDER

摘要

The treatment of complex products from hard materials is accompanied by loss of stability of the cutting process, which leads to oscillations, causing an increase in the wear of cutting tools, reducing the longevity of the machine actuators, which ultimately affects the quality and accuracy of processing responsible products. The aim of the work is to investigate the effect of the multiple layers cutting tool holder construction. The different layers are made from plastically deformed steel. The different plates have a anisotropic structure and have different mechanical properties. This construction is considered as a method to improve the effectivity of the cutting tool and helps to reduce the oscillations in the finishing turning. We hereby propose a method for the construction of the multilayer damper instrument holder together with a mathematical model suitable for processing hard materials.
