Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following performance criteria: - following relevant safety procedures; - obtaining and interpreting relevant drawings, job instructions and specifications; - selecting correct electrode to ensure that the finished product conforms to specification; - determining the coordinates of the work pieces relative to the machine datum; - calculating machining parameters necessary to achieve the safe, accurate and efficient machining of the work piece; - calculating the surface area of the electrode; - positioning work piece and electrode to enable the safe, accurate and efficient machining of the required feature(s); - producing components to specification, and; - checking machined components for conformance with specifications.Students will also be expected to demonstrate the following knowledge: - safety hazards associated with the use of electro-discharge machines; - the job requirements; - the sequence of operations to achieve the job requirements; - the electrode type and geometry required to achieve the specified outcome; - the effects of material to be machined on the electrode material and geometry; - the procedures for producing electrodes for the electro-discharge machining process; - the coordinates of the feature(s) to be machined; - the coordinates of the electrode relative to the machine datum; - the procedures for operating the electro-discharge machine to produce components; - the tools, techniques and equipment appropriate to the checking of machined components; - the procedures for checking machined components for conformance to specification, and; - the reasons for selecting the tools, techniques and equipment to be used.
