We calculate for you 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 a degree-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 you 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 you add the the Cam-Follower. |
1.Add a 2D-Cam - see Machine elements toolbar > Add 2D-Cam If the new 2D-Cam is one from a pair of Conjugate-Cams, or it is one flank of a Groove-Cam 1.a. Add a Conjugate-Cam FB - see Machine elements toolbar > Add Conjugate Cam FB 1.b. Edit the Conjugate-Cam FB to select least two 2D-Cams - see Conjugate-Cam dialog. 2.Select a 2D-Cam or a Conjugate-Cam FB as the Power Source for the Follower - see Configure-Power Source 3.Review the 2D-Cam : Display, Properties, Roller-Life, Cam-Life, ... - see 2D-Cam dialog 4.Add a Cam-Data FB - see Kinematic FBs > Add Cam-Data FB 5.Edit the Cam-Data FB to link it to the 2D-Cam- - see Cam-Data dialog : Cam Analysis 6.Connect wires from the Cam-Data FB to a Graph FB to analyse 5 parameters - see Cam-Data dialog : Cam Analysis 7.Edit the Cam-Data FB again to calculate the Cam's Coordinates - see Cam-Data dialog : Cam-Coordinates |

If Force-Analysis is important
Configure the Power-Source and select the 2D-Cam - see Configure Power-Source Add Mass-Properties to the important Parts in the model - see CAD-Line dialog Add Force Data FB to plot Torques, Forces over a machine-cycle - see Force-Data FB, Add Spring FB If the Cam-Part is actually a Cam-Shaft, then edit Motor - see Servo-motor and Gearbox |
Edit the 2D-Cam
Select and edit the 2D-Cam to open the 2D-Cam dialog. You can display its Pitch-Curve, edit its color, the thickness of the cam-profile, ... You can estimate the Roller-Life and Cam-Life. |
Analyse the Cam over a Machine-Cycle the 2D-Cam to
Add and edit Cam-Data FB and link it to the 2D-Cam you want to analyse - see Add Cam-Data FB and Cam-Data FB dialog : Cam Analysis Analysis parameters include: Maximum Shear-Stress, Contact-Force, Radius-of-Curvature, Pressure-Angle, Sliding-Velocity |
Calculate and export the Cam-Coordinates in different formats
Add and edit a Cam-Data FB , edit link it to the 2D-Cam you want the Cam-Coordinates - - see Add Cam-Data FB and Cam-Data FB dialog Cam-Coordinates Calculate the Cam Coordinates as XY-Points or Biarcs. Export the Cam Coordinates as TXT, DXF, STEP, or export the Points or Biarcs directly with SolidWorks |
