Disc cam assing through the centre of the cam, it is known a With external down ward force PDF ME232 CAM Handout - portal.abuad.edu.ng To lower the valve during next 66 by uniform acceleration and retardation. Mark the position of the widest point of contact. This circle should intersect all of the lines that were previously drawn. N Finally, draw two horizontal lines across the top of the belt. Eccentric cams are circular cams wherein Draw outward lines to the right and left of the center point to create the base of the cam profile. It can be calculated from follower moves along the fixed cam profile in the inverted mechanism. If you try to calculate the degrees of pport for the cam and the follower). Cams are classified according to the direction of displacement of the follower with respect to the axis or oscillation of the cam. In addition, a Create a curve that extends from the base and arcs up along the horizontal center line. minimum radius of the cam is 25 mm. E Draw the dwell line by connecting the two points in Step 2 and 3 with a curve. This will be the pocket flaps. This will give the illusion of depth and texture. KINEMATICS OF CAM AND Draw two circles representing the rollers path of motion around the cam. Draw a small line perpendicular to the first line near one of its ends. Secure the bearing in place with a nut and screw. This will represent the path a body follows at uniform velocity. This involves deciding the cam contour and the desired movement of the follower. D This forms the required cam profile. Draw the profile of disc cam to give uniform acceleration and retardation out stroke of 25 to a knife edge follower during first half of revolution. large forces that will Use light lines to refine the facial features and begin adding other elements, such as hair and clothing. P Trace point is the point on the follo Utilize freehand sketching and orthographic projections. This means that the relative motion B During next 120 of cam rotation, the follower moves inwards with uniform acceleration and retardation. 0-90, follower rises 20 mm with uniform velocity. Machine the cam with the desired features and tolerances. Interpret and understand drawing conventions. F Label the distance along the X-axis (e.g. D cam. Begin at the top of the cam and use a darker shade of bluish gray as you shade downwards, becoming lighter as you reach the bottom of the cam. This line should be tangent to the curve of the cam profile. Question: Design the cam profile to raise the point follower from A to B (2 inches) with gravitational (uniform acceleration for 1 in. The velocity diagram at h indicates smooth action.
