The items in this section are for the display and editing of global cam specifications. The items in this section are for the display and editing of the current selection in the displacement diagram. Check 2. Check 1. Check this if you would like milling information to be output to the worksheet. Check this if you would like dimensions to appear on the final drawing. The rotations per minute of the cam. Used to determine velocity and acceleration. Maximum follower displacement. Used only to scale the display of the cam displacement diagram in this dialog. Radius of the prime circle. Press this button to remove the currently selected line or zone. Press this button to add a new line in the selected zone or after the currently selected line. Radial displacement of selected center line. The selected zones transion type. Angular displacement of selected center line. The rotations per minute of the cam. Used to determine velocity and acceleration. Maximum follower displacement. Used only to scale the display of the cam displacement diagram in this dialog. Radius of the prime circle. Radial displacement of selected center line. The selected zones transion type. Angular displacement of selected center line. Press this button to display the follower acceleration graph in the area to the right. There is a line intersecting the graph at the point of maximum acceleration for each nonlinear curve. Select a line to see its values. Press this button to display the follower velocity graph in the area to the right. There is a line intersecting the graph at the point of maximum velocity for each nonlinear curve. Select a line to see its values. Press this button to display the follower displacement graph in the area to the right. Select a zone in the diagram to set the curve type. Select a line to set angular and radial displacements. The horizontal scale of the diagram. Its values represent angular displacements about the cam. Cam displacement diagram.
