how to design a 3D cam profile in nx
(OP)
Does anyone know how to model a cam profile using given data's as polarcoordinates of roller follower centre, roller radius, minimum radius of cam in nx???

1. I would make it all in AutoCAD, and save file as *.dwg
2. open drawing in Catia 5.xx (just click on file-open-select dwg,...)
3. select the profile in the drawing, COPY
4. go to the part file in Catia
5. insert a sketch in that part file
6. whele in sketch : PASTE
7. OVER
8. save as a step file and open in it in UG.
OR make it in Catia 5.xx, export as a stp file and open it in UG.
Sometimes we have to use multiple programs. There is no program doint it all at the fast speed.
If no Catia license use Solid Works or,...

The polar coordinates ?
Do you want to automate the process ?
( neither do i understand what Nikon speaks about, but I don't think that post was serious.)

use the attached excel file to convert the polar into Cartesian coordinates.
Then export data from excel into a text file and change the extension into *.dat file and import into NX using File-->Import-->Points from File.
With this points you can create a spline using the Fit curve command.

RE: how to design a 3D cam profile in nx
I tried this method once and unfortunately got the cam profile to be wrong.
Thing to be noted Roller's center polar coordinates are only known not the point where the cam gets in contact with the roller if so i could use this method and this might work.
Actually i used this by converting my coordinates by subtracting the roller radius to get the contact point but only for dwell regions it works and for a rise and falls to get the tangential contact, my method of subtracting the roller radius fails.
As for non practical method is concerned
Points of roller center's are been imported from an excel file as the above mentioned method
now roller circles are been drawn on one point and then it can be patterned to all other points(Say for example if we have coordinates for each angle we get 360 circles this too increases if the angles are incremented by 0.5 degree)
now tangential line is drawn from one roller to other separately
similarly for one roller to other and from that one to the next one the process is continued
finally the profile may be completed
as of dwell portions is concerned there wont be any problem since we could use an arc
The problem is using this much operation in the sketch the system is not able to take up the load and slows down and my time to model it gets increased so practically its not possible.
Searching for a way which is easier than this
Thanks for people who have responded till now :)

BTW, the method you described above is basically what you'd find if you were to look at the 'Cam Design' section of the 'Machinery's Handbook'.

Insert > Spline> through points > points from file.
you need to put all the co ordinates in a notepad and then change its extension to .dat
