Week 9 Machining with Planer Challenge
Explicit Dynamics Analysis on Machining with Planer system
Objective
To perform an explicit dynamics simulation on Machining with Planer system in two Case Cutting Velocities, they are
Case 1: with a cutting velocity of 15000mm/s
Case 2: with a cutting velocity of 20000mm/s
To find out
- Equivalent Stress
- Total Deformation
- User defined temperature of body
Material data
Figure. 1 shows the Structural steel's properties in Ansys Workbench engineering data. It was used in the Machining with Planer system model's as Cutting tool material input. Figure. 2 shows the Steel 1006's properties in Ansys Workbench engineering data. It was used in the Machining with Planer system model's as Workpiece material input.

Conclusion
- Total deformation of Case 1 (15000mm/s) is higher than Case 2 (20000mm/s) and Similarly Equivalent Stress i higher in case 1.
- Temperature is higher in Case 2 compared to Case 1 and Case 2 has completely machined where as Case 1 is not
- From this comparison maching will have smooth and good surface finish in Case 2 hence it should be considered.
