5. For the cam displacement below with maximum rise of 25 mm, design a disk cam with roller follower graphically. Assume that the cam rotates in anti-clockwise direction. Let the minimum diameter of the prime circle be 60mm. There is an offset of 10 mm between the cam and follower axis. The diameter of the roller is 20 mm. Show your construction clearly and label your diagram. (You must use ruler and compass for the graphical construction). [15 points]
A cam drive is used for a mechanism incorporated in a shoe-sewing machine.The cam follower must rise outward 0.5 in. with cycloidal motion in 0.7 s, dwellfor 0.2 s, fall 0.25 in. with cycloidal motion in 0.5 s, dwell for 0.2 s, fall 0.25 in. withcycloidal motion in 0.5 s and then repeat the sequence. Determine therequired speed of the cam and graphically plot a follower displacementdiagram.
A plate cam with reciprocating follower is driven by a constant speed motor at 199 rpm. The follower starts from a dwell and accelerates to a uniform velocity of 598 mm/s, and maintains this velocity for 34 mm of rise. Determine the cam rotation angle (in radians) for this uniform velocity segment. Answer: age Next page Fir Tim Type here to search
P A cam drive is used for a mechanism that moves a tool in an automated screw machining process. The cam follower must rise outward 24 mm with harmonic motion in 0.2 s, dwell for 0.3 s, fall 10 mm with harmonic motion in 0.3 s, dwell for 0.2 s, fall 14 mm with harmonic motion in 0.2 s, and then repeat the se- quence. Determine the required speed of the cam and graphically plot a follower displacement diagram.

Create a cam profile based on the displacement diagram below.These are the details for the cam follower set up: Roller follower with diameter of 10 mm Base circle of 50 mm Clockwise motion
Design a cam in non dimensional form consisting of 5 sections, each having the following characteristics: Determine equations for the cam profile for each section and box your answers for clarity. Hint: For each segment write the boundary conditions and apply them to the corresponding equation. Segment 1: (0 < y <) Has a cubic profile: Y = Ay³ + By² + Cy + D Starts from zero Dwells at zero Rises to the height of 4/3 Dwells at the height of 4/3 Segment II: (< y < 1) Dwells at the height of 4/3: Segment III: (1 < y <¹) Has a parabolic profile : Y = Ay² + By + C Starts from the height of 4/3 Dwells at the height of 4/3 Declines to the height of 1 Segment IV: (< <) Has a linear motion: Y = 4y - B Starts from the height of 1 Segment V: (

The cam follower rises outward 0.75 in with constant velocity for the first 90 degrees of the motion cycle and to dwell for 130 degrees, fall with constant velocity for 45 degrees, dwell for 95 degrees, and then repeat the sequence. Graphically plot a follower displacement diagram. Use the motion equations and a spreadsheet to plot a displacementdiagram of the follower.
For a plate cam with translating offset follower with knife-edge similar to the following Figure, the offset e=10mm , radius of the base circle 7 = 40mm . The cam rotates counter-clockwise. The follower has the motion as same as the previous problem. Please design the cam profile by graphical method by pencil and keep auxiliary lines. 77T
2. The reciprocating radial roller follower of a cam is to rise 3 cm with a Simple Harmonic Motion (SHM) in 120°, dwell for 60°, then return with a cycloid motion to its starting point in 120°, and finally dwell for the remaining 60°. If the prime-circle radius is 3 cm, draw the displacement diagram, and then the cam profile for clockwise cam rotation (if the roller-circle radius is 0.5 cm).
