We calculate the 2D-Cam from the relative motions of the Cam-Part and Follower-Part, together with the shape of the Cam-Follower.
Add 2D-Cam does NOT remove any Degrees-of-Freedom.
Cam / 2D-Cam : |
A Cam (2D-Cam element) is a curved profile or surface that imparts a displacement (a motion-law) to a Follower by either point or line contact with a Cam-Follower. |
Cam-Part : |
The Part to which we add the 2D-Cam |
Cam-Follower : |
The shape of the sketch-loop and Profile / Extrusion that is in continuous-contact with the 2D-Cam. |
Cam-Follower Part : |
The Part to which we add the sketch-loop and Profile as the Cam-Follower. |
1.YOU ARE HERE: Add a 2D-Cam - see below IF the new 2D-Cam is a Conjugate-Cam or a Groove-Cam (or other Body-Closed Cam): 1.a. Add a Conjugate-Cam FB - see Add Conjugate Cam FB 1.b. Edit the Conjugate-Cam FB to add at least two 2D-Cams - see Conjugate-Cam dialog-box. 2.Select the 2D-Cam or the Conjugate-Cam as the Power Source for the Follower - see Configure-Power Source 3.Review the 2D-Cam : Display, Properties, Life, ... - see 2D-Cam dialog-box 4.Add a Cam-Data FB - see Add Cam-Data FB 5.Edit the Cam-Data FB to link it to the 2D-Cam- - see Link the Cam-Data FB to a 2D-Cam 6.Connect wires from the Cam-Data FB to a Graph FB to analyse 5 parameters see below 7.Edit the Cam-Data FB again to Calculate the Cam-Coordinates - see Cam-Coordinates dialog |
