Machined Groove In Sheet Metal
Machined Groove In Sheet Metal
(OP)
Hello All,
I came up with a design, but I'm not sure if this particular machining operation will cause issues. We have a 1/8" (3.175mm) thick sheet of aluminum 5052, and we need to machine an o-ring groove 1.96mm deep. Would this be a costly and difficult procedure?
Thanks!

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

If someone gets the bright idea of punching any of the holes or shearing the edges, the part will distort enough to screw up your o-ring depth tolerances.
You will probably get calls about the part for as long as it's in production.

Clearly the words of someone who has little or no knowledge of compound pierce and blank tools or fine blanking tools.
Whilst a router or CNC mill is probably the best way to go do not rule out a press tool, especially a fine blank tool if quantity allows for this within the budget.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Fineblanking along with semi-piercing might be a good way to process the part, provided that the quantities justify the purchase of the die. The OP does not state quantities to be produced: it may only be one.

Please do not be condescending just state the facts how a punch
will not leave sharp edges. or what can be done to improve punching. I have a few years experience with punching, I am sure
I don't know it all.
secondly It's not wise to criticize an other one statement. milling or routing will definitely be a much improvement but will be expensive for high volume parts.
but can easily be done for R&d or low volume.
Depending on the quality & quantity there can be a compromise.

Chem etching is a solution ( A strong alkaline is used for aluminum.). However it would take longer than a CNC mill or router.
The part would also have to be masked, and chem etching is notorious for eching at different rates unless a chem-etch quality material is used.
