    Material
In summary, the conversation is about determining which material would have the highest material removal rate when using die sinking EDM. The tool and workpiece are both made of copper, stainless steel, and aluminum, and the same input parameters will be used for all three materials. The participant believes that aluminum will have the highest MRR due to its low melting point, followed by copper and then stainless steel. They also mention that copper may have the lowest TWR due to its low electrical resistivity. They ask for confirmation on their answer.

hi guys,
which one of those material you think it should give highest material removal rate by using die sinking EDM.

the tool is copper and workpiece are
1. copper
2. stainless steel
3. aluminum

lets assume the same input parameters will be used for those three material

thank you

Welcome to the PF.

What do you think is the right answer and why? :smile:

Thanks.
my answer is that the highest MRR should be achieved from Aluminum then copper then the stainless steel the reason for this is that Aluminum has the lowest melting point compared with others
And regarding the TWR i think when we machine copper we get the lowest TWR because the electrical resistivity for copper is the least one.
just want to make sure my answer is correct or not?
 

What is MRR?

MRR stands for Material Removal Rate and is a measure of the amount of material that can be removed by a machining process in a given amount of time.

How is MRR determined for Die Sinking EDM?

MRR for Die Sinking EDM is determined by the combination of cutting speed, electrode wear, and the dielectric fluid used in the process. These factors can vary depending on the material being machined.

Which material has the highest MRR for Die Sinking EDM?

Copper has the highest MRR for Die Sinking EDM due to its high electrical conductivity, which allows for faster cutting speeds and less electrode wear.

What factors affect MRR for Die Sinking EDM on Copper, Steel, and Aluminum?

The main factors that affect MRR for Die Sinking EDM on these materials are electrical conductivity, melting point, and hardness. These properties can vary greatly between materials, resulting in different MRR values.

How can MRR be improved for Die Sinking EDM on Copper, Steel, and Aluminum?

MRR can be improved by optimizing the cutting parameters such as cutting speed and electrode wear, as well as using advanced dielectric fluids and efficient electrode materials. Proper maintenance and calibration of the EDM machine also play a crucial role in improving MRR.
