Abstract

This study represents a case study in thermal and wear analyses for cutting tools, and investigates a relation between temperature distribution and wear characteristic of the tool. This paper presents computer modeling of tool deformation and thermal load during machining using finite element method. The relationship between heat and wear was investigated using both numerical analyses and finite element method.<BR />The results from the thermal analyses indicated that maximum temperatures on the contact area ranged from 163 to 957.5 ºC for the uncoated tool while those ranged from 33.6 to 83.4 ºC for the coated tool. In other words, the temperatures for the uncoated tool are higher than those for the coated tool. This is expected due to the less contact area resulting from the coating. Therefore, it is worth manufacturing cutting tools with coatings both to extent tool life time and to prevent wear. <BR />It can be concluded that the standardized image processing algorithm should be developed for analyzing wear especially for mass production. It has been proved that the coating material enabled to resist wear, to decrease the cratering and improve the surface topography.
