: Connect these points using a French curve (leka) to form the smooth working profile of the cam. Key Elements of a Cam Drawing
To construct a cam profile according to standard engineering requirements: : Establish the coordinate axes ( ) and define the center of rotation for the cam. Base Circle : Draw the minimum radius circle ( rminr sub m i n end-sub
