This work presents the analysis of the vibration amplitude, surface roughness and TiAlYN coated and uncoated tools performance during milling AISI P20 steel. The lack of studies about the relationship between vibration amplitude, surface quality finishing and tool performance has motivated the present work. The choice of AISI P20 steel is due to its application in mold manufacturing, given its high wear resistance, thermal fatigue and high quality finishing requirements. The present study involved a set of milling experimental tests with the variation of the cutting length by using coated and uncoated TiAlYN tools. These were performed with cutting machining parameters under lubricant conditions. The analysis included the measurement of the vibration amplitude in three orthogonal directions, the surface mean roughness, and the analysis of tool wear by microscopy. The results show that the coated tool leads to a lower vibration amplitude, weariness and mean roughness compared to the uncoated tool. Also, it is shown there is a direct relationship between the vibration amplitude and the surface roughness. Thus, coating the tool with TiAlYN showed better results in protecting the cutting edge, which made the performance of the tool more stable over time with lower vibration amplitudes.

摘要

This work presents the analysis of the vibration amplitude, surface roughness and TiAlYN coated and uncoated tools performance during milling AISI P20 steel. The lack of studies about the relationship between vibration amplitude, surface quality finishing and tool performance has motivated the present work. The choice of AISI P20 steel is due to its application in mold manufacturing, given its high wear resistance, thermal fatigue and high quality finishing requirements. The present study involved a set of milling experimental tests with the variation of the cutting length by using coated and uncoated TiAlYN tools. These were performed with cutting machining parameters under lubricant conditions. The analysis included the measurement of the vibration amplitude in three orthogonal directions, the surface mean roughness, and the analysis of tool wear by microscopy. The results show that the coated tool leads to a lower vibration amplitude, weariness and mean roughness compared to the uncoated tool. Also, it is shown there is a direct relationship between the vibration amplitude and the surface roughness. Thus, coating the tool with TiAlYN showed better results in protecting the cutting edge, which made the performance of the tool more stable over time with lower vibration amplitudes.
