Engineering graphics and design / P2 NSC EC / November 2020 LE QUESTION 2: CAM AP ST Given: · The detail of a camshaft and a follower in its lowest position. · The centre lines of the cam profile. Specifications: · The follower reciprocates on the vertical centre line of the camshaft. · Minimum distance from the cam profile to the centre of the camshaft = 15 mm. · Rotation = anti-clockwise Motion: The cam imparts the following motion to the follower: · It rises 10 mm with uniform motion over the first 30°. · It rises 25 mm with uniform motion over the next 30°. · It rises 20 mm with uniform motion over the next 60°. · It descends 10 mm with uniform motion over the next 60°. · There is a dwell period for the next 60°. · It returns to the original position with uniform motion over the rest of the rotation. Instructions: · Draw, to scale 1 : 1, the given camshaft and the wedge-shaped follower detail at its minimum position. C · Show the direction of rotation on the cam profile. · Draw to a rotational scale of 360° = 120 mm and a displacement scale of 1 : 1, the complete displacement graph for the required motion. · Label the displacement graph and include the scale. · Project and draw the cam profile that would generate the given motion. · Show ALL necessary constructions and projections.
