be minimised? Hazards associated with the hand fitting activities involve injuring yourself on equipment and tools‚ this can be done due to wear of equipment and in proper use of tools‚ to avoid this you should check over the tool you are about to use and make sure that it is in safe working condition. You should also make sure that you are in safe working condition when going to use tools or machinery‚ for example when using machinery that rotates at a ahigh speed you should make sure that you are

Electro Discharge Machine and how it functions and what is needed to make it function Electro Discharge Machining (EDM) is a process‚ where we use the electrical energy to produce electrical waves and thermal energy to mould any alloy into a desired shape/size. This machining method can only be used with materials that conduct electrical energy well. EDM is so powerful that it can cut through into hard steel without the need to soften it. This method is not only used to shape steel but it

sustainability as Mukhopadhyay (2010) mentioned. Moreover‚ in some cases‚ mechanical micromachining is even more precise and flexible than conventional CNC machines. In this study‚ the performance of mechanical micromachining‚ conventional machining‚ electrical discharge machining (EDM) and non-conventional micromachining are compared in three ways: potential and efficiency‚ sustainability‚ and limitations. The further development is also provided in this study. Introduction Increasing intensity of competition

EVALUATION 1. EDM (Electrical discharges machine ) and WEDM ( Wire Electrical discharges machine). • Fundamentals of process; Principles of EDM Electrical Discharge Machining (EDM) is a controlled metal-removal process that is used to remove metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape. The metal-removal process is performed by applying a pulsating (ON/OFF) electrical

1. TEN GREAT LOW-COST TEACHING TOOLS Educational material created by Prof. Alejandra Masís Artavia‚ 2011. 2. INTRODUCTION This presentation’s aim is to provide teachers with ten low-cost teaching tools. Moreover‚ it seeks to explain the importance of using these tools and how they can be used in several ways‚ as Kevin McCaughey states in his article. 3. Tool 1: Scissors (and scratch paper)Importance of using scissors: they transform a single piece of scratch paper into 10‚ 20‚ and even 50 paper
