To add a 2D-Cam, you must select two elements:
•Part - which becomes the Cam-Part.
•Profile/Extrusion - which becomes the Cam-Profile.
Before you can add a 2D-Cam, you must prepare the model to include these two elements. You must also specify the motion for each.
Cam Terminology : |
Description and definition. |
Translating Cam-Follower : |
the output slides along a straight axis. |
Rotating Cam-Follower : |
the output rotates about a fixed axis. |
Reciprocating : |
a non-progressive, translating motion. |
Oscillating : |
a non-progressive, rotating motion. |
Non-Progressive motion : |
a motion that returns to its original position after each machine cycle. |
Flat-faced Cam-Follower : |
a planar surface in continuous-contact with the Cam. |
Roller Follower : |
a circular shape in continuous-contact with the Cam. |
•Design a Cam to move a Reciprocating Cam-Follower, with a Flat-Faced Cam-Profile.
•Design a Cam to move an Oscillating Cam-Follower, with a Flat-Faced Cam-Profile.
1.Model two different kinematic-chains:
a.a Slider for the Translating Cam-Follower, and
b.a Rocker for the Oscillating Cam-Followers.
2.Add a Profile to the Slider / Rocker to represent the Flat-Faced Cam-Followers
3.Add a continuously rotating Crank as the cam shaft.
4.Add the 2D-Cam element
