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.

Project 4: Cam-follower is used in a range of applications to convert rotational motion to linear motion of a follower at specific characteristics and time period. Your role is to construct the profile of a cam that specify the following motion requirements of a follower: Motion.1: first part of lift period at constant acceleration of 2 m/s? over rotation of 30° Motion.2: second part of lift period at constant deceleration of 2 m/s? over the next 30° Motion.3: follower produces constant displacement for next 90° Motion 1 and 2 are the rise/lift period and must be 15 mm displacement and the fall is identical to rise/lift period and must return to the base again at 210°. The base of the circle cam is 140 mm. Produce the profile of cam for 2°intervals and find out speed of cam in rpm and the corresponding time interval for each segment of the profile. Provide both a table of data and final sketch including all the information on it. 1. Explore the profiles that will achieve a specified…

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: (

Design a single-dwell cam to move a follower from 0 to 2 inches in 60 deg, fall 2 inches in 90 deg, and dwell for the remainder. The total cycle must take 2 seconds. Use the polynomial method to design s v a j functions. Plot the s v a j diagrams.

A cam drive is used for mechanism that drives an automated assembly machine. The cam follower must rise outward 13 mm with constant velocity in 3 sec, dwell for 3 sec, fall 5 mm with constant acceleration in 2 sec, and then repeat the sequence. Determine the following for the given problems: 1. Calculate the time for a full cycle 2. Calculate the required rotational speed of the cam 3. Determine the cam rotation for each follower motion interval 4. Plot the displacement diagram

A cam drives a flat reciprocating follower in the following manner. During the first 90° rotation of the cam, the follower moves outward through a distance of 30 mm with SHM. The follower dwells during next 90° cam rotation. During the next 90° cam rotation, the follower moves inward with SHM. The follower then dwells next 90° cam rotation. Draw the cam profile and calculate the maximum values of velocity and acceleration when cam rotates at 10 rad/s.
