Flat-Faced Follower Circular-Arc Cam

Create a parametric 2D cam profile for a flat-faced translating follower, based on the following reference design from a published cam-follower study. Reference dimensions: - Base-circle radius r1 = 19.5 mm - Nose radius r2 = 21.0 mm - Circular flank radius R = 55.12 mm - Distance between the base-circle center and nose-circle center d = 7.0 mm - Required follower lift h = 8.5 mm The geometry must satisfy: h = d + r2 - r1 = 8.5 mm Construct the cam using circular-arc geometry consisting of: 1. A base-circle region with radius 19.5 mm 2. Circular flank sections with radius 55.12 mm 3. A circular nose section with radius 21.0 mm 4. Smooth, tangent transitions between the flank and nose 5. A symmetric cam profile about the vertical centerline through the nose Do NOT invent dimensions that are not provided above. Do NOT use a polynomial or arbitrary spline motion law. Do NOT change the base-circle radius, nose radius, flank radius, center distance, or required lift. Where angular transition information is required but not uniquely specified by these dimensions, determine the transition from the circular-arc tangency geometry rather than arbitrarily choosing an angle. Create the result as a clean, closed, manufacturable 2D cam profile suitable for export to a CAD system. Keep all major geometric dimensions as editable parameters.
