Week 9 Machining with Planer Challenge

Objective

In this study, i performed an explicit dynamics simulation of planar machining to find out the Equivalent Stress, Total Deformation and also insert a User defined result to calculate the temperature of the body. I performed 2 cases. One is with a cutting velocity of 20000mm/s and the other is with a cutting velocity of 15000mm/s of tool

This study is done in Ansys 2022

Procedure:

1.Geometry

• Input the model as Step format in geometry in explicit dynamics module of Ansys.

2.Material assignment

• Open Engineering Materials and select the required material from explicit material list.
• Tool is made of structural steel material and workpiece is made of steel 1006

3.Meshing

• Mesh method for tool: tetrahedron
• Mesh generate for workpiece by sizing of edge division: 10

4.Boundary condition

1.(a).Connection

.Frictionless contact : Tool and workpiece

Body interaction

1.(b). Input the fixed support: workpiece

1.(c).Input the velocity 15000m/sec : Tool

5.Analysis setting :

End time: 0.00075

6.Results (output): for 15000m/sec

Equivalent Stress

Temperature:

Total deformation:

Result for other cases at different velocity:

7.Conclusion:

Equivalent stress is approximately similar to both velocity cases but the temperature for velocity 20,000 is higher.
