PROJECT TOPIC: OPTIMIZATION OF CAM FOLLOWER MECHANISM LINKAGETO DRIVE WITH GIVEN TRAJECTORYINTRODUCTION The cam profile mechanism is selected for the final project. It significantly encompasses fundamental Mechanical Engineering concepts. Notably, it can widely be used in different applications which require attainment of specific output motion different from the source powering which is often reciprocating. In the given case for the project, a particular translational motion in the upward and downward fashion is to be achieved from the cam follower as illustrated (Shalaa & Likaja, 2013). Industrially, such mechanisms are useful especially in ensuring effective mechanical control of load-bearing robots; For instance, if we want to achieve movement of the arm in a particular direction, the given mechanism can be adopted in such a way that the robots arm moves accordingly under relatively simple configurations (Ya’an et al, 1999).). Admittedly, therefore, the focus of this project will be on how the cam profile can, in an optimum fashion, be configured to drive the linkage within the required trajectory. The illustration for this mechanism is given in figure 1.PROJECT DESCRIPTION But what is so special about this optimized mechanism? Firstly, two control parameters are often critical for effective and economic performance of the cam follower; namely: the speed and direction of the follower (Yildiz & Demir, 2017). In this project, therefore, the given cam profile traces the project requirements as far as speed control is concerned. Further technical details can be derived to show the performance of the follower in terms of actual speed output. Moreover, timely acceleration during actualization of motion is required. This is also achieved with the configuration of the cam mechanism (Mali1, Maskar , Gawande & Bagi, 2012). As mentioned earlier, the required direction follows the given trajectory which will be in both upward and downward direction. Therefore, at the conclusion of this project, certainly the common motion mechanism in mechanical engineering shall have been gained tremendously. This project offers an impetus for further work in kinematic design of robots. The complex robot’s drive configuration originates from the simple mechanisms of the cam follower (Sahu, Kedia & Sahu, 2016).Admittedly, the motivation for this project is based on how the two critical performance parameters are effectively controlled by optimizing the given mechanism (Goris, 2004& Shao, Xiang, Liu & Lili, 2016). It greatly offers an opportunity to interrogate the given design mechanism so that further robot kinematic design can be actualized. CONCLUSION Although the project will partly comprise the derivation and determination of the arm acceleration, it is not clear in the project how that can be achieved as the focus is just on speed and direction (Demeulenaere, & Schutter, 2002)). Therefore, for further work, fundamental proposal on the design to accommodate effective acceleration control given the input power and motion is recommended. Besides, significant work on the testing methodologies need to be
