AI Thread Summary
Aluminum is expected to yield the highest material removal rate (MRR) in die sinking EDM due to its lower melting point compared to copper and stainless steel. Following aluminum, copper is predicted to have a moderate MRR, while stainless steel is anticipated to have the lowest. The tool material, copper, results in the lowest tool wear rate (TWR) because of its minimal electrical resistivity. This discussion confirms that the choice of workpiece material significantly affects MRR and TWR in EDM processes. The analysis aligns with the understanding of material properties in machining applications.

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?
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
