Academic Year 2020/21P22006 CADCAM Systems (eng760s1)Second Attempt – Coursework (CAM)Deadline For Submission:23th July 2021, 21:00Submission Instructions:Submit to Moodle (CAM part only)Instructions for completing theassessment:All Creo model files zipped into a single file and the Report file (PDF orWord)Examiners:Dr Krassimir Dotchev, Dr Ivan Popov 2020-21 Page 2 of 3P22006 CADCAM SystemsSecond Attempt – Coursework (CAM)Aims:1. To develop comprehensive knowledge in application of concurrent engineering concepts usingintegrated CAD/CAM/CAE software tools in modern design and manufacture.2. To develop confidence and capability in the effective use of industrial standard CAD CAM CAEsystems.Learning outcomes1. Critically evaluate current CAD/CAM/CAE technologies and their application to enhance engineeringdesign and manufacture.2. Employ and critically evaluate a range of CAM approaches and CNC simulations in order to planmanufacturing processes, optimise manufacturing time/ cost, and produce NC data for efficientproduction.Submission:Submit your files to Moodle Second attempt drop box before the date and time specified at the title page asfollows:1. Zipp file – all Creo files from the CAM working directory zipped into a single file. (100Mb maximum size)2. Report file (PDF or Word)Notes: Check that the zipped file contains ALL necessary files. Before zipping the files, make sure that theycan be opened with PTC Creo without any problems. Submit the entire CAM folder and the Report file.Late Submission:Submission/ assessment – in accordance to Academic Regulations, University of Portsmouth, AcademicRegistryTasks to be carried out:1. Import the provided 3d part model to Creo and use it as reference part for the CAM model. Create asquare block as a workpiece having sufficient allowance to machine the top part of the model (noneed to machine the bottom and the sidewalls of the square base). (10 marks)2. Create a process plan and set up a manufacturing process using a 3-axis CNC milling machine tomachine the part in mild steel. Select appropriate machining sequences including finishing of the topsurface and the 4 corner holes. Configure the relevant cutting tools for them. Create and observe thetool path cutting simulation of each sequence. (50 marks)3. Select/calculate appropriate cutting parameters and use the CADCAM system to estimate themachining time for each sequence and operation. (20 marks)4. Report – present all your work with relevant comments, screen captures, and discuss the main 3DCAD CAM principles. (max 2000+-500 words). (20 marks)Assessment:Assessment grades for this course work will be based upon your Creo files/models and submitted report. Toqualify for each grade, the minimum expectation is listed.50-60% Submission shows a reasonable understanding of the learning outcomes. A reasonably good CAM models andsimulations were developed demonstrating reasonable understanding of the main CADCAM applications. Briefdescription of the required tasks illustrated with screen dumps and discussion on CADCAM systems advantages anddisadvantages have been presented in a report.60-70% Submission shows a very good understanding of the learning outcomes. As above and also developing areiterative approach to improve the CAM and machining time optimisation.2020-21 Page 3 of 370% + Submission shows a thorough understanding of the learning outcomes as applied to the problem area. Athoroughly professional report demonstrating excellent CAM optimisations, including discussion on CADCAM systemsadvantages/disadvantages and identifying the key features and functionality.Additional tutorials/supporting materials in electronic format located in:www.port.ac.uk/MoodleDotchev K., Popov.
