Orthogonal Machining In ABAQUS

[@snehilsrivastava7436]

A big thanks brother. Great work. You have shown step by step how to do a machining simulation.👍👍

[@pinalrana]

Glad it helped

Hi thanks for the video. could you please tell me which paper you referred to get the parameters of the material AI2024

[@awzin-x8z]

can you please share the pdf, its not opening in google drive now

How to get Tool wear rate using Usui wear model in Abaqus?. If you have any idea about how to calculate tool wear rate using abaqus or any other software do let me know.

[@kimhuynh7362]

Thank you so much. Although I follow your tutorials, I can't simulate the models.

[@pinalrana]

Please let me know the error.

[@tinkupreethi]

Nice Video!! Thanks for sharing

[@pinalrana]

Your welcome

How to contact you bro

[@benjamincffoster4574]

What does the subroutine code? Why do we need it?

[@mengzhang9144]

Thank you very much! Could you please repost the Google drive file?

[@pinalrana]

Updated.

[@ownagain]

@@pinalrana Thank you! The file is a Fortran code, I was wondering if you can share the pdf with the problem statement and material properties.

[@pinalrana]

Salam How can I make the chip not overlap each other and into the piece? Thanks

[@pinalrana]

You need to change failure criteria according.

[@nekkaryounes631]

@@pinalrana where can I find this setting (failure cretira ) exactly ? Thanks

[@pinalrana]

In Johnson-Cook damage for displacement (7:35 in the video). Discontinuous chip is generally observed in a brittle material. So, you also need to change the properties accordingly.

[@MultiSaded]

Thank s for this tutorial. Do you have an idea on the machining simulation of a composite material?

[@pinalrana]

Sorry, I don't have any background in composite material.

[@benjamincffoster4574]

did you do it

[@nekkaryounes631]

Salam, I have 'i5 4 ram' pc.Can I use it for simulation Withe abaqus /explicite (I need to simulate orthogonale cutting) Thanks

[@pinalrana]

Yes sure.

[@hannahweber3451]

First of all thank you very much for this video! May I ask you a question? I did an orthogonal cutting simulation with a rigid tool... my van M.-stress is about 8e8 Pa so 800 MPa, wich seems normal for my parameters. But my reaction forces RF1 and RF2 at the reference point are quite high. The max RF1 is like 150 000 N (0.15e6) (I'm using SI units kg, m, ..) In my understanding the reaction force RF1 at the reference point in orthogional cutting should be the cutting force wich would be more like 1000 N max. Are your reaction forces also that high? Or do you have any suggestions?

[@pinalrana]

You can check your boundary conditions and material properties?.

[@AkulaSriRahul]

Aluminium is ductile, so the chip formation should be continuous , serrated and not break apart into discontinuous chips like we see in the simulation. How should we rectify this?

[@pinalrana]

To do so you have to use modified Johnson-Cook or incorporate Johnson-Cook plasticity.

[@AkulaSriRahul]

@@pinalrana I'm new to all the this ,could you please guide ? Can you pls explain how did we take a specific value, in this case 0.0001 for disp at failure in the damage evolution? Where should those changes be made since there is only one Johnson cook option. Should viscoelasticity be selected under elasticity options?

[@AkulaSriRahul]

@@pinalrana Also, if we use titanium alloy for workpiece , can we use the same procedure with only changing Johnson cook parameter values , keeping displacement at Failure as 0.0001?

[@pinalrana]

@@AkulaSriRahul yes you can.

[@AkulaSriRahul]

@@pinalrana Can u explain why we used that value for displacement at failure ?

[@mishrasanskar7210]

Sir how to change feed rate in this model

[@pinalrana]

In the present simulation study you have only 2 parameters depth of cut and speed. Feed is equal to width of cut or width of workpiece.

[@ankitsingh873]

From which papers did you took the properties of workpiece and tool as in your document it was cited as [16] and [17]. Kindly send that paper also as it will be helpful.
