Module Learning Outcomes

The following module learning outcomes and professional body learning outcomes are tested in this assessment: 1) Use appropriate CAM tools to simulate the parts machining and machining time optimisation. (EA1b & EA3b)
	Assessment task and specific terms
Machining Tool Path Simulation & Machine Time Optimisation Introduction Each student will submit an individual report of no more than 10 pages including the front page, figures, tables and references. The report has to be compiled with the font size of Arial 11 point or Times New Roman 12 point and appropriate margins and 1 line spacing. Layout Format: Academic style. References Style Harvard and Vancouver. There is no maximum number of images and diagrams. Online submission through CANVAS and only PDF format is allowed. This section is worth 10% of the overall assessment for this module. Typical hours required by each student to complete this assignment is 10 hours. For your reassessment you are required to: Demonstrate a good knowledge and understanding of generative machining using NXCAM module to do the machining of the following part of the Air-Engine as shown below. Also you are required to do a detailed optimisation of the machining operations taking into account all machining elements which can affect the machining time. students are also required to re-design their parts if needed to reduce the manufacture cost (i.e. machining time) and also you are required to design and implement a modular fixture design and clamping techniques to be used for this part. Figure 1 – Crank Web of the Air Engine Requirement To produce a machining setup which include tooling and all machining operations needed and test each operation of the above part using the NXCAM module of Siemens package and also each machining time operation should be optimised, the design of a flexible fixture and clamping technique to be recommended for the part. Student are required to develop a good knowledge and understanding on the whole manufacturing process in creating and editing CL-Data (Cutter location Data) to the post-processed data which is  directly feed to  the CNC machine tool in form of a tape file (Machine code data - G & M code). In order to achieve that the students are required to go through the following steps: Creating face milling and volume clearance operations Creating simple and complex profile operations Setting machining parameters for hole making operations Machining time optimisation Create a CL data Create a tape file using a three mill postprocessor (Machine Code Data- MCD).
