I am working on designing a simple can opener that consists of an adjustable round blade and a can holder and I would like to know what materials I should use for this device, thank you!
I'm guessing here that this is probably for a school project, so a little research on your part is required. Having said that, you need to be looking along the lines of hygienically safe plastics and metals as obviously the materials will be used to open cans of food. The can opener will also be exposed to water so any metal needs to be anti-corrosive. The round blade will also need to have some form of tensile quality so that it maintains its sharp edge.............
Time for you to make Google your friend young Grasshopper!
One could also used either Vibranium or Adamantium.
Vibranium is stronger than adamantium...
Dave, what's with all the questions on materials?
Are all these questions coming from a class of students at a particular university?
I think I may need to talk to the teacher to give some advice on how to teach Google...
Yep! Another couple of them tonight (my time). Looks like your services are in high demand. I was just filling the gap in your absence lol.
Actually, I'm surprised they're not going straight to 3D ContentCentral or GrabCAD.
Oooops! Did I just let the cat out of the bag!
What a team we make Dave. We even got the different hemispheres covered.
I know, all we need now is a snazzy logo (maybe one of the students could design something) and a catch phrase!
Cut and paste (a man's new best friend)
Lol I appreiciate the help and the humor on the question, the reason im asking here is because we need to show we consulted professionals in order to pick our materials correctly, im sorry if it seems to be unprofessional on my behalf but thats the reason im asking here
I appreciate you comments.
Can I ask you a few questions?
What makes you think there are any Professionals on this forum?
Is it possible that this forum is just a bunch of students talking to each other?
If you pass along a material suggested here, how can you confirm that a Professional gave you the advise?
What does you teacher require for proof that you consulted with a Professional?
What would help is your question being presented is as Professional a manner as possible.
Imagine you are sitting in a Professionals office. Your are paying this Professional a large consulting fee. You are paying per minute of his time. What information does the Professional need in order to properly access and determine the best answer?
Now ask yourself, Have I given that level if information here on the forum?
Okay I see your point,
What we were asked is to basically ask for information on this forum because according to him this forum is being used by engineers that may help us.
The proof of the consultation will be provided as a screenshot of the conversation here.
With that being said I can see in your profile that you are an Engineer so I guess my teacher isn't totally wrong,so may I ask what information do you need in case you still interested in helping me please?
The forum can be a good place to start, however there are also a lot of us that are "Not" Engineers, just designers using SW for our jobs. Sometimes it can be an awesome place to assist in Software issues and user assistance...
Your question is based on a specific project that we haven't seen any drawings or pictures of and normally when someone just posses a question without a model or pictures, it appears like people want us to do their work etc...
To be honest, you could have mentioned you have a project to work on and you are searching for a legit Engineer that can do a finite analysis or just assure the proper materials are used. For an Engineer to give you this info, #1 he/she needs a Drawing or a Model - and the second #1 is money for services rendered. Unless you are up front and layout the project and say you're a student, their are retired guys here on the forum that at times just want to help someone out, but first they want to see what you have done.....
Also - just a heads up there are a lot of people here on the forum that use an alias, so you never know who you're dealing with..........
Describe, in as much detail as possible, the operating conditions of this can opener.
Here is a picture of a simple can opener... (I have a couple of these and have actually used it to open cans)
Is this opener a powered device? Hand operated?
What kind of cans are going to be cut?
What material are these cans made out of?
What plating is on these cans?
Are you intending to cut the can from the top or sideways thru the bead?
What is the life expectation of the opener? (How many cans should it cut before failure?)
Are you designing built in obsolescence?
How is the rotation accomplished?
How much force do you expect to see on the cutting blade on first contact?
How much force do you expect to see on the cutting blade during use?
Have you completed an initial design concept yet? (if so kindly post you assembly)
How will you confirm that my recommendations are correct or even appropriate?
I want to add to my questions...
What materials have you researched already?
What material would you select based on your research? What lead you to that conclusion?
Have you considered platings?
Have you considered different cost of raw materials and manufacturing cost differences?
What quantity will you be manufacturing?
There are more questions. I hope you see that Engineering is not really as easy as asking a question.

Come on John. My picture clearly shows that I am Ironman. What more proof do you need?
Yeah - ok - What the other people don't see in the picture is the two world champion body builders holding up your hands, right.........
I would prefer Rubabackium over the Vibranium
Max Bassis I had just thought of a very hard material that would work for a can opener "Astralloy 8000" that's good stuff
I have a prototype of the model I was thinking of designed in SW already, I just don't know how to upload it here?
I think that if ill find a way to send you what I have so far you will have a general idea of what im looking
Reply to a message on this forum.
When the dialog box pops up, click on Use Advanced Editor in the upper right corner
In the lower right corner click on Attach.
Have your design PackandGo as a Zip file and attach that.
I totally agree with everything that both Rick and John have said to you here. Both guys are knowledgeable and helpful and aren't coming from the point of a personal attack. There's been a sudden influx lately of students placing very vague posts asking for advice, usually about materials but some about design, for their school projects. Now there is no harm in asking for help, it's how we all learn but virtually not one single student so far has offered up one shred of any form of evidence that they've done research so far themselves which is annoying. I would also add that in my opinion, for your lecturer to guide you to this forum alone for advice on materials rather than use "Google" or other known standards is poor form on his part. If it was for advice on CAD, then yes, that would be different. Personally, I think you could have been better guided IMHO.
P-38 and P-51 Military Can Opener
These are the unassmebled parts of what I was thinking about, I hope it is helpfull.
Thank you for your patience, if ill have any further questions in the future ill make sure to provide all the necassery info about what I need and what I have done so far.
And there it is...
The P-38 Military Can Opener is known by some as the “Army’s Greatest Invention”.
They are stamped from cold rolled steel right here in the United States.
Make the can opener from cold rolled steel... (tongue firmly in cheek)
Well. you got a good start there.
Have you tried to assemble the parts?
I did and I can't quite figure out where the cutting blade goes in relation to the other 2 pieces.
Can you kindly take a few moments and do the best you can to answer the list of questions I posted above?
Is this opener a powered device? Hand operated? Hand Operated
What kind of cans are going to be cut? Food cans, like tuna,pickles etc...
What material are these cans made out of? Aluminum sheets
What plating is on these cans? Zinc
Are you intending to cut the can from the top or sideways thru the bead? From the top
What is the life expectation of the opener? (How many cans should it cut before failure?) About 1000 cans
Are you designing built in obsolesce? Im sorry but I don't know the meaning of that word
How is the rotation accomplished? I was thinking that the rotation is accomplished by the movement of the blade
How much force do you expect to see on the cutting blade on first contact? 200 Newtons
How much force do you expect to see on the cutting blade during use?70-80 Newtons
Have you completed an initial design concept yet? (if so kindly post you assembly) I didn't assemble the parts yet
How will you confirm that my recommendations are correct or even appropriate? Ill use the SW analysis
I have not tried to assemble the part yet
This is the assembled part, just did it, this is what I expect the final product will be.
