DESIGN A NEW CRICKET BOWLING MACHINE PDM TANG WAI FONG ELSA My Supervisor: Dr. Chris Sutcliffe

Thank you for my supervisor Dr Chris Sutcliffe Thanks a lot

Summary • To develop the reactions and techniques • non-powered system at low cost • lightweight, portable, accuracy, repeatability and precision • both outdoor and indoor use • safety guard is also designed to that machine for safety use

Project Objective (Part 1) – To make a market research or analysis of the existing products – To design a new cricket -bowling machine for practice to develop reaction and techniques. – To set out a comprehensive design methodology for all the phases of the product specification, product planning, product design, and development of the manufactured processes for the technical system.

Project Objective (Part 2) • To know the aerodynamic of the ball and the force applied to the ball. • To create a conceptual drawing and how to find out a nonpowered system to propel the ball in the proper way. – To develop, design and test a non-powered system for controlling the speed. – To create detail CAD drawings – To produce an assembly drawing for the device.

Project Objective (Part 3) – To make animation, photo-realistic shading model, or mechanism how to operate the machine. – To make some finite element analysis to test the stress and strain in the device. – To define the manufactured processes and calculate the costing. – To draw up the conclusion and results for the machine – To prepare a manual for the user.
