The objectives are to edit the Design-Set to:
|•||Make the radius-of-curvature of the two cams have a minimum value of 20mm|
|•||Make the radius-of-curvature of the two cams to have equal maximum values.|
Measure the Cam Radii of Curvature
Note: You can also use a Measurement FB and measure between the centre of the cam and the cam contact-points.
Display the Graph:
Each 2D-Cam has two Cams: Cam 1 and Cam 2. Thus, you can also plot, Radius-of-Curvature 1, and Radius-of-Curvature 2.
For each Cam, use the Y-axis data-channel drop-down [to the right-side of the graph-plot area] to select which Radius of Curvature you want to plot - RoC1 or RoC2?
For this model, with two different cams, there is a small '2' next to their contact-points. Thus, we want to plot the Radius-of-Curvature 2 for the two cams.
To read the radius-of-curvature values in the graph-plot
As you drag in the graph area...
You can edit the Minimum and Maximum graph-plot values in the Graph Settings dialog-box.
I have changed the maximum and minimum of the two graphs to ±100.
Measure the Minimum and Maximum Radius of Cam Radii of Curvature
Do Steps 1 and 2 again for the other Dwell Segment
Edit the Design-Set
Edit the dimensions to make the Radii-of-Curvature equal.
The model updates as you edit the dimension in the Design-Set.
If it does not, then click the Rebuild icon in the Design-Set.
Note, it is best to put the Number-of-Steps parameter in the Machine-Settings dialog-box to ~100.
See Edit menu > Machine Settings > Cycling Parameters > No-of-Steps.
