Week 9 Machining with Planer Challenge
Machining with planer
Objective:
To perform the explicit dynamics stimulation for planner machining using ANSYS workbench.
Procedure:
Importing the given CAD model in space claim in order to check any geometry malfunction. then assigning properties and material for the geometry. 
body intersecting connection is provided with frictional contact. In order to generate mesh we need to perform edge sizing by selecting the four edges of the rectangle and the element should be hexahedral. Also we need to use path confirmation method for the cutting tool with elements of tetrahedra's.
we need to give a fixed support for the workpiece in order to avoid moving during cutting process.
We need to provide different velocities for the two cases for the cutting tool which should be in the X direction of the component.
velocity of 20000mm/s & velocity of 15000mm/s
Results:
Case 1- velocity of 20000mm/s
Total deformation
Equivalent stress
Temperature
Case 2- velocity of 15000mm/s
Total deformation

Case 2 |

21.912 |
640.13 |
359.41 |
Conclusion:
In case 2 the stress development is less than the case 1, The temperature is less in the case 1 hence proves that increasing in the velocity leads to increase in temperature as well as deformation
