Explicit Analysis of Machining with Planar
Explicit Dynamics of Machining with Planar was done for two different velocity of Tool in planar and subsquently Equivalant stress , Total deformation and and temperature of body was calculated for both Cases.
Set up for the Simulation
Material
The Workpiece was assigned Steel 1006 and tool was assigned structural steel.
Meshing
Mesh Metrics was assigned as follow:
CASE 1 : When velocity of tool is 20000mm/s
Total deformation
The total deformatioin eas observed to be 34.313mm for velocity of 20000mm/s.
Equivalant stress
The equivalant stress was observed to be 439.4MPa
User Defined Temperature
The temperature was observed to be 367.77 degree celcius
CASE 2
When tool velocity is 15000mm/s
In this Case
Total Deformation
Total deformation was observed to be 23mm
Equivalant stress
The Equivalant stress was observed to be 634.15 MPa
Temperature
The temperature was observed to be 364.75 degree celsius.
CONCLUSION
1. The total deformation in 1st case with tool velocity having 20000mm/s is higher as compared to that in planar having velocity of 15000mm/s.
2. The equivalant stress in case of 2nd Case with tool velocity of 15000mm/s is higher than that in tool having velocity of 20000mm/s.
3. The temperature observed is almost same in both the cases.
