creare wolf camma departing from excell file

[slickfish]

Hi.
I press that I searched in the forum but found nothing.. .
I designed a camshaft for a racing engine with the help of a motor engineer,
which provided me with all the up curve and relative degrees in an excell file that I will send to the company
producer of the tree.
But now I would like to do some checks in the 3d axieme so I built the camshaft, but in a way to say little "empirical", that is with a series of lines departing from a center, as long as the raised in the different points to the degrees data, I joined the points with spline and then extruded the profile.
Obviously when I go to do mating with the tip, sw tells me that there cams is not correct because not extruded from a single profile, so I wanted to know if there is a way to create the profile of the cams importing the excell data with the ups and degrees.
Thank you very much

there is the curve function through xyz points that can be connected to a excel table.
Maybe that's enough to solve it, otherwise you need the model to understand and analyze the problem thoroughly

Thank you so much!
I tried this function, I should rewrite all the excell file with xyz data of the points.....x0, z the raises, but y I have to calculate the distance every °.
However I used curves through points of reference, but that cannot be extruded....is something wrong?

Thank you.

no curve can be extruded. are reference entities.
However, they can be converted into sketches. you select the cirva and you make convert entities

you are right, but also converting the curve turns it into spline and we are point and end,
I don't come out... .

if you attach the file you can try to understand the situation otherwise you will guess not knowing neither how the cam is made nor how the assieme is managed

 

[MassiVonWeizen]

cam coupling also works with splinec
as the guide says
to add a pair of tips:

• create a cam part:
  • create a profile of lines, strings and tangent splines. the profile must form a closed loop.
  • It's profilo.
• create a pointy part. the part to be paired must be one of the following:
  • cylindrical face
  • face planar
  • Summit

I don't know. of the cam, of the mating property manager. . .

I'll train you an extruded lobe so you can analyze the situation, can it be enough?

 

[MassiVonWeizen]

does not work because the sketch of the cam is not completely tangent.
insert the tangences between the arc and the ends of the spline and resolve.

 

[slickfish]

excuse my ignorance, do you intend to select bow and spline and give it a tangency report?

 

[MassiVonWeizen]

Try it doesn't cost anything... Anyway I meant that

 

[slickfish]

ah ok...I did it but the profile always remains open and does not allow cam/punteria coupling

 

[MassiVonWeizen]

something wrong because I tried it and it works
the tangences must be two, one per end of the arc

 

[slickfish]

Maybe I'm not able, would you tie me the lobe with the right sketch?
Thank you very much

 

[MassiVonWeizen]

I have later version and you wouldn't do anything about my file besides learning the error.
I attach you a video of how to add relationships and how then cam mating functions
View attachment camma.zipwhen, in the video, I delete the sketch lines is only to not have too many entities, among other things useless, and to be able to select better

 

[slickfish]

But come on, then there's something wrong, I did just like this, but it doesn't work, when I put in the relationship, a strange arrow comes out on the junction point. .
I'll try again later, thank you, though.

[MassiVonWeizen]

If you can't do this, you can put a ray on the edges, basically where the ray and spline attack is.
try both doing it in the sketch and using the function; put a radius value large enough not to inflate the curve and the cam works

 

[slickfish]

Hi.
and nothing....I tried in every way, the problem is not resolved.
with tangence does not work, if I try to radiate the edges in the solid does not allow me, instead if I try to radiate from sketch tells me that impossible because it would eliminate one of the two elements, that is the cause of everything?

and with a description you can understand what this is Strange arrow?
learn to correct questions with understandable images

 

[slickfish]

I apologize, in attachment the image of the arrow, I think it is the tangence, it is possible to iron it by taking it from the point.
Perhaps I have to activate some setting while I apply the tangence...boh I don't know... I have tried all the
