Temperature Measurement and Finite Element Modeling Methodology for Laser Cutting of Stainless Steel Plate

Article Preview

Abstract:

The article is focused to the temperature measurement and methodology of computer modeling of laser cutting process on stainless steel plate. Microstructure of stainless steel and dimension of the kerf width was obtained. The temperature was measured with two K-type thermocouples by digital convertor NIUSB9211. Obtained temperature dependences were used for simulation 2D and 3D models creation by ANSYS software. The results of the model application with SHELL and SOLID elements are shown. Numerical simulation showed effect of nitrogen gas on heat dissipation and is also one of the reason why isn't total energy received in the material. Author considered 3D model with impinging jet flow whose proposal is in the article as the model closest to reality.
