Week 9 Machining with Planer Challenge

MACHINING WITH PLANAR CHALLENGE

OBJECTIVES

                  In this challenge we have 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. You need to perform this for 2 cases. One will be with a cutting velocity of 20000mm/s and the other will be with a cutting velocity of 15000mm/s.

PROCEDURE

• First, we have to input the engineering materials with required properties or else by creating with required properties.

• Then we have to import our model into ansys, import the model and open it in space claim and cut the model into half so that the academic version support.

• Then we have to delete the connections and body interface is created default.
• Then mesh the component with required mesh size in this assignment we will use
  • Mesh      – default
  • Nodes – 6557
  • Elements – 10071

• Analysis setting give the end time as 7.5e-4 and assign fixed support and velocity.

• Then give the required solution parameters then solve.

RESULTS

Case 1: 20000 mm/s

Total Deformation

Equivalent stress

Equivalent strain

Temperature

Case 2: 15000 mm/s

Total Deformation

Equivalent stress

Equivalent strain

Temperature

Conclusion

From the above stimulation in case1 has higher velocity than case2 hence in case 2 the workpiece is not fully sheared approx 5mm is left out in worpiece and the temperature in case 1 is higher because of highvelocity compared to case 2 is around 13°c.
