Week 9 Machining with Planer Challenge

Aim: 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.

Setup: We begin by assigning the required material to the workpiece(Steel 1006) and deleting all software generated contacts.

We mesh the cutting tool using a patch conforming method with tetrahedrons and edge sizing of 10 divisions on the workpiece.

The end time for the simulation is then entered in analysis settings, here 7.5e-4.

We provide a fixed support to the workpiece and velocity to the cutting tool.

For Case 1 the velocity is 20m/s and for Case2 it is 15m/s

Results:

	Directional Deformation(mm)	Equivalent Stress (MPa)	Temperature (K)
Case 1	12.345	698.2	586.97
Case 2	8.3293	692.83	574.92

Conclusion: Due to the lower velocity we can see that the deformation, stress developed and the change in temperature in the 2^nd case is lower than the 1^st.
