Greetings,<\/p>\n

<\/p>\n

I would greatly appreciate your support in understanding the problem with my simulation. I am trying to simulate 2D orthogonal machining of Ti-6Al-4v with Johnson cook plasticity and Johnson Cook Damage Model. Material cutting takes places , however there is no chip formation and my objective is to study the temperature distribution in both chip and tool. <\/p>\n

<\/p>\n

I have read through the previous discussions and accordingly tried all trouble shoot methods (as per my understanding). Below is the image of my boundary conditions and results: <\/p>\n

<\/p>\n

\"Deformation\"<\/p>\n

<\/p>\n

I have tried with smaller mesh size but no chip formation. I have attached the file without results for your review. Would greatly your response and apologies if the answer is already present in another discussion. I went through and tried all different discussions on the topic but couldn’t figure it out. <\/p>\n

<\/p>\n

Secondly, I have seen studies were people say they conduct 2D studies at different feed rates (mm\/rev). How do we simulate the effect of different feed rates in 2D? Softwares like AdvantEdge, which is specially built for machining, also has an option for setting different feed rates in 2D. However, I am unable to physical understand the meaning of this or how to simulate this in 2D. <\/p>\n

Gratitude for the support.<\/p>\n
