Week 9 Machining with Planer Challenge

Report Week 9 Machining with Planer Challenge

Aim: Perform an explicit dynamics simulation of machining with planer. find out the Equivalent Stress, Total Deformation and also insert a User defined result to calculate the temperature of the body. 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:

Import geometry

Material:

Insert explicit material steel 1006 for work piece. Cutting tool is rigid structral steel.

Mesh:

Use Tetra mesh method for cutting tool

Use edge sizing for 4 edges of work piece, number of devisions is 10

Final mesh

Analysis setting

Boundary condition

Fixed support

Velocity: for case 1 x =20000mm/s, y=0, z=0, for case 2 x =15000mm/s, y=0, z=0

Result:

Case 1:

Deformation:

Equivalent Stress:

Equivalent Strain:

Temperature:

Case 2:

Deformation:

Equivalent Stress:

Equivalent Strain:

Temperature:

Conclusion:

velocity	Directional deformation	Total deformation	Equivalent Stress	Equivalent Strain	Temperature
20,000	26.756	34.316	439.72	1.3648	367.7
15,000	26.147	32.836	660	1.4779	364.75

From the table, it is observed that the valus of directional deformation of case 1 is 26.756mm and case 2 is 26.147mm. The equivalent stress of case1 is 439.72MPa and in case 2 is 660MPa. The temperature of case1 is 367.7 degree and in case2 is 364.75 degree.
