Week 9 Machining with Planer Challenge

AIM:We will have to perform an explicit dynamics simulation for machining with planar

Objective:

We will 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.

CASE-1: cutting velocity of 20000mm/s

Procedure:

• Start the ansys workbench and click on Explicit dynamics and rename it "machining_planer".

• Double click on the engineering data and add steel 1006 material from the explicit material,as shown below.

• After that right click on the geometry and import the geometry available in the question. And again double click to edit in spaceclaim, but here no need to edit every thhing looks good.

• After that we have to close the spaceclaim and right click on model and click on update,then double click to edit in mechanical module.Then rename the geometry as workpiece and cutting tool , and assign the material to workpiece as steel 1006 and cutting tool stifness behaviour as rigid as shown below.

• In the mesh i added method as the tetra hedron for cutting tool and add face sizing for the edges of workpiece and type as division and given value 10.

• After that we have to go to analysis setting there we have to give the end time as 7.5e-004 and rest is as it is.
• Then we need to add the boundry condition so here we have to fix the one side of workpiece and add velocity to the cutting tool so here in the first case it is 20000mm/sec so directly give the value in x direction and constrain other to axis by putting value as 0.

• Now we have to add all the output data asked in the question so add total deformation and equivalent stress but the temperature is added after the simulation we have to clic kon the soluton and then click in the worksheet in the tool bar and select the temperature and righ click to add user defined result.

Results:

Equivalent Stress:

• The max von mises stress is 652.38 Mpa.

Total deformation:

• The max deformation value is 41.551 mm.

Temperature:

• The max temperature rise is 383.14 C

CASE-2: cutting velocity of 15000mm/s

Procedure :

• Nothing is changed only the velocity of the cutting tool is changed from 20000 mm/s to 15000 mm/s.

Results:

Equivalent Stress:

• The max von mises stress is 663.47 Mpa.

Total deformation:

• The max deformation value is 31.147 mm.

Temperature:

• The max temperature rise is 374.5 C

Conclusion:

As mentioned in the question i did both the case and in compare to first case where the velocity is 20000mm/s the case 2 where velocity is 1500mm/sec is having less deformation.

NOTE: IN my archive file for the first case by mistake i made changes witout copying the model so it's not showing the process is completed but it ih having the result inside the model kindly check that.
