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 body. Perform 2 cases:

Case 1: Cutting velocity 20000 mm/s

Case 2 : Cutting Velocity 15000 mm/s

Execution:

Follow The below steps

1. Use explicit dynamic module.

2. Open engineering data and select steel 1006 from explicit material.

3. Import the model .

4. open the mechanical module .

Since W/P is under consideration change the stiffness behaviour of the tool to rigid and assign material steel 1006 to W/P.

5. Remove the default bonded contact.

6. Insert meshing method for the tool and assign the method to be tertahedron.

7. select 4 short edges of the workpiece and divide into 10 division as shown below.

8. Generate mesh.

9. set analysis setting as shown below.

10. Insert velocity for the cutting tool and assign 20000 mm/s for case 1 and 15000 mm/s for case 2.

11. Insert fixed support for the Workpiece.

12. Solve

Result and observation :

Case 1 :

1. Total Deformation : Max Deformation = 34.316 mm

2. Equivalent stress : Max stress = 439.53 MPa

3. TEmperature : Max temp = 367.77 °C

Case 2 :

1. Total Deformation : Max displacement of the tool = 23.61 mm

2. Equivalent stress : Max stres = 634.34 MPa

3. Temperture of the Body. Max temp = 364.74 °C

	Case 1	Case 2
Total Deformation (mm)	34.316	23.61
Max Equivalent stress (MPa)	439.53	634.34
Temperature °C	367.77	364.74
