Creo Parametric - Variable Section Sweep - Wavy Washer (Demonstration)

This Creo Parametric tutorial shows how to create a wave washer / spring washer using the Variable Section Sweep tool and Relations with the trajpar parameter. In addition, it incorporates Parameters and Flat to Screen 3D Annotations.

nice video.I love it.

[@esrAsnataS]

Thanks, for this. I set mine up differently, used the circle as internal diamater as that is how you buy washers and added an outer diamater calculation.
Kept me amused for an hour or so this morning.

Good point, I didn't think about that. Yes, you usually choose washers by ID.

[@adnanzubairi92]

But it's round can we add for equally waves our requirements round values

[@CADPLMGuy]

?

i am a little confused about trajpar. I wrote the relation "sd4 = 0.1*trajpar" . I expected it to go from a height of 0 at start to 0.1 at the end but it didn't generate anything. what am I doing wrong?
My understanding is that trajpar is a location variable along the trajectory and height at particular location along the trajectory will be defined by "0.1*value of location variable at that point i.e trajpar"

[@GullNoor]

i tried it with a straight line trajectory and it worked

[@meharsamba]

Can you please make a 'mixed flow' impeller ?? Not the radial flow but mixed flow, so that the vanes are bending from being vertical at one end to horizontal at outer end....please ?

[@CADPLMGuy]

I’m not familiar with that.

[@meharsamba]

@@CADPLMGuy its like a closed radial impeller but the the inside (eye of the impeller) vanes are horizontal, and the end of those vanes (i.e. outside) is vertical. Its like a surface/cross section , which is vertical in orientation, is following a path/arc (like a sweep) and ends up being horizontal.

[@CADPLMGuy]

Okay. I still don't know how to design it.

[@meharsamba]

@@CADPLMGuy hmmm can i send you a picture of it or something ??
