How to draw radial cam profile with a roller follower

- In this video I have explained, how to draw cam profile with a roller follower and axis of follower passing through the cam center. Motion of follower is assumed to be SHM during ascent and uniform acceleration and retardation during descent.
Great insight from you Dr Joji Thomas. My only observation is that another circle with the min. radius should have been drawn so that the drawn curve will meet the circle at the last stage of the dwell.
Yes. Thank you
Very helpful sir thanks for doing such a good video for students
Amazing video sir
Exam m same question aya tha
Thanks video k liye
Thank you, from Kenya!

last formula was right??
Sir how do circle radias
Dr sir displacement diagram is wrong where is the return dwell.... Actually angular displacement cam must be 360 degree
For drawing cam profile, displacement diagram of rise and return only needed. You can even eliminate dwell at top also. Also you don't need to draw rise and return angles with some scale, you can take any arbitrary length for each.
@@drjojithomas thanks sir doubt clear
I have some really old winding machines that take heart shape cams one is .250, .230 and .186. I believe these numbers are the distance between the bobbins. Or winding area. can you help with a formula to make these?
Sure
Nice sir 👍❤️
How do we obtain length of 1' 2' 3' ...
Use divider and set distance 11' in displacement diagram and mark it in cam profile diagram. This way mark all other points.
But we are not given distance of 11'. Thanks
@@user-gv7zi8kp5k using lift of the stroke you should draw displacement diagram as explained. Automatically you will get 11', 22',33' etc

You are best
Why don't we draw prime circle to this problem sir
we must draw prime circle. The first circle drawn is prime circle.

Which software do you for drawings?
only power point presentation(it is very time consuming)
How to this sir
A symmetrical circular cam operates a roller follower with a lift of 30 mm. The minimum radius of the cam is 50 mm. The roller radius is 18 mm and the nose radius is 12mm. The angle of lift is 80°.If the speed of the cam is 210 rpm.find the main dimensions of the cam ,and acceleration of the fallower at
a) the beginning of the lift and
b) the apex of the nose
Highly legendary

Hai sir .
Hello
Send mobile number pls.we have cam .not able to take point
Need your help to design

Cam profile you draw that is wrong
But u did not draw a prime circle
Only circle drawn is prime circle of radius 32.5 mm. It is clearly mentioned. Base circle not drawn as it is not required to draw profile in this case
Thank you sir
