Computer Simulation for 2D Temperature Distribution in Orthogonal Metal Machining
Cutting heat and ternperature is one of the important phenomena and has a great influence on the metaI machining processes.Based on the modified Iarrangian Finite Element Method for the deformation connected closely with the heat.a mathematical model with 2D in orthngonal machining has been built up with triangular elements of 309,and nodes of 200 for the work.chip,and tool.Frictional boundary condition is imposed onto the interface between the work and the tool face.as one heat source.The heat from shearing on the shearing plane is another heat source.The material to machine is supposed to be of continuum and homogeneity.Programs have been Successfullv executed and comparison is made betweert the simulation and experiments,and reveal the good agreement between then.One of the findings from the study is that the temperature and pressure tenters are homocentric and located a distance from the tooI edge,accounting for the common wear of the tool crater.taking thecutting 0f 45 steel as all example.
