Question
For the cam-follower mechanism in the figure, the cycloidal movement program is shown below:

LOW DWELL (Rest or Stop) for 45 °
3 mm rise at 135 °
HIGH DWELL (Rest or stop) for 45 °
Drop or drop 3mm at 135 °
If the base radius is 21 mm, what is the coordinate RX1 in mm of the cam profile if θ1 = 153 degrees? Use as many decimal places as you can. The follower is of the wedge type (knife edge).

Answer #1

From the given data:

Low dwell = 0 degree to 45 degree

rise segment = 45 degree to 180 degree.

so at 153 degree, angle turned in rise segment is 108 degrees.Given that O, = 1539 Low Dwell = 45° and Rise in 135° segment Radius = Base 21 moon So, at O, - 183, in the rise segment, 0 =
