Week 9 Machining with Planer Challenge
Objective: To perform an explicit dynamics simulation to find out the Equivalent Stress, Total Deformation and also insert a User defined result to calculate the temperature of the planar with workpiece
Setting up analysis: Steel 1006 is added to the workpiece as geometry is imported into ANSYS mechanical.
The Stiffness behaviour of the tool is kept rigid.
Mesh: Tetrahedron method is opted for meshing the tool and face sizing option is selected for the workpiece where edges are selected and instead of giving number of elements, number of divisions of 10 are given as the worpiece is flat rectangular.
Boundary conditions: Velocity is given to the tool and workpiece is fixed
Solution:
Case 1: Velocity 20000 mm/s
Analysis settings
Total deformation
Equivalent stress
Temperature
Case 2
Analysis ssettings
Total deformation
Equivalent stress
Temperature
Result:
The results obtained are tabulated below
| Velocity(mm/s) | Total deformation(mm) | Equivalent stress(Mpa) | Temperature('c) |
| 20000 | 34.6 | 467.9 | 367 |
| 15000 | 32.8 | 659 | 364 |
Conclusion:
As we can observe, the stress is increased in the second case.
