Separating Circular part in Solidworks

Separating Circular part in Solidworks

Separating Circular part in Solidworks

(OP)
I have a circular part which I created in solidworks. I want to split the part on one end and open it up x.x amount of degrees. This will be a molded part, and I am doing this for the mold. After the part is done, it should be able to come back into a perfect circle.

Problem is, I do not know how to do this to my model, or redraw it to show the split.

Any tips???

Thanks

I am not familiar with that feature. Where is it located. I will look in solidworks help to see if I can find anything about it.

schmimk,

   You may be looking at some weird engineering.  It sounds to me that your part must be some shape such that when you load it, it will bend itself into a circle.  

   Once you figure out what that shape is, you model it using SolidWorks' loft feature.

We spend all of this time learning to communicate with geometry - let's communicate with geometry.  Attach your file here (if proprietary simply create a dummy file the exhibits the same behavior to illustrate your design intent).

RE: Separating Circular part in Solidworks

Circular is 2D, did you really mean cylindrical, or perhaps spherical?

RE: Separating Circular part in Solidworks

(OP)
yes, cylindrical.

picture a washer (made of a flexible mat'l of course), but I want that washer to have a split on one side and just wondering how to model that, so that when the washer closes back together will be perfectly circular, or cylindrical if you will.

RE: Separating Circular part in Solidworks

draw the washer,

create a new sketch, draw a line were you want it to split.

exit sketch, goto - insert - features - split

select the split line

push the cut bodies, let it assign names to the 2 new parts.

click ok

the new parts will be in the same folder as the original, just put the 2 in an assembly and put a degree mate on the 2 faces.

RE: Separating Circular part in Solidworks

In the free / unstressed case is the cylinder open or closed?  Either way, the open shape corresponding to a perfect circle when closed will depend on how the forces which cause it to change shape are applied.

A first approximation would have a circular cross-section with the same thickness as the closed shape and inside and outside arc lengths which match the inside and outside circumferences of the closed shape.
