Abstract:

The article presents the topic of boring using a tool with a mechanical vibration damper. These types of tools are particularly useful when boring holes that exceed five diameters in length. A comparative analysis of the machining effects was made using the example of sleeves made of C55 steel, machined using a conventional boring bar and equipped with a vibration damper. The comparative factor was the roughness parameter Ra. Machining was performed using a CNC lathe for three cutting speeds and two tool feed values. Using a program to calculate the profitability of using individual cutting tools, the manufacturing costs and time using these two boring bars were compared and conclusions were drawn.
