ASSIGNMENT 3 Hybrid Machine

This is a Group Assignment (2 or 3) students.

PART 1 The use of CAMWorks has some clear benefits when the complexity of the geometry of the part in either 2D or 3D geometry increases. In this assignment you are required to generate CNC code for the nosecone from Assignment 2 by using CAMWorks rather than writing CNC code using CIMCO and SolidWorks combined. Read and do (as required) the exercises from the CAMWorks Mill_Tutorial.pdf, “Chapter 1 Learning 2 Axis Mill Basics” and “Chapter 2: Learning More 2 Axis Mill” from the tutorial “CAMWorks 2016 Mill Tutorial 2017.pdf” (available from the Week 10 folder) in order to gain further familiarity with CAMWorks. The SolidWorks models are also available from the Week 10\CAMWorks Mill Examples folder. Chapters 3 and 4 may well be useful in this Assignment. 0. Model the nose cone from Assignment 2 in SolidWorks. 1. In CAMWorks, define the machine to be used and change its parameters to match those of your 3D Printing machine defined by your group in Assignment 2. You will need to establish what feed rate your machine is capable of. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 2. Use a Long Series 10mm Ball nose cutter (T4) header to generate CNC code. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 3. Select the M3AXIS-TUTORIAL Post Processor supplied. 4. Define the stock size. You may assume a suitable grade of ABS for the material 5. Define all of the machinable features by using either the Automatic Feature Recognition (AFR) feature and or Interactively Created Features. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 6. Edit / Remove any Rough Finish Machining Features generated as your group decides. Only one finishing cut on the surface of the nose cone is required in this Assignment. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 7. Generate an Operation Plan. Delete any operations that are decided to be not necessary by your group. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 8. Generate a Toolpath and select a pocketing pattern that maximises the quality of the surface finish. Your group may like to run a few different patterns to establish your final selection. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 9. Simulate the Toolpath and document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight. 10. Post Process your group’s Toolpath for the nose cone and attach it to your report in zip format.

2. Customizing CAMWorks Post Processors Part 2 http://www.youtube.com/watch?v=oH0LGqd3se8

1. Use UPG to develop a Post Processor for your hybrid machine using M3AXIS-TUTORIAL Post Processor as supplied with CAMWorks. The Post Processor that your group develops does not have to be perfect but it must improve on the standard M3AXIS-TUTORIAL Post Processor supplied in at least two areas. Document each step of the process and any difficulties that your group encounters using screen grabs and comments that show insight.

UPG does not need a license manager to operate. It can be used as supplied in the Week 9 folder.

2. Provide a conclusion and recommendations (with references) in of the use of CAMWorks and

UPG. 3. All files generated for this Assignment are to zipped together in one file named with the SIDs of

the group members e.g 43076548_43067982_43012524.zip and uploaded to Blackboard.

This Assignment is due on Friday the 3rd of November 2017 (Week 13) at 11:00pm via Turnitin. This assignment is worth 10% of your mark for AMME5902

THIS ASSIGNMENT SHOULD TAKE AN AVERAGE GROUP OF STUDENTS 12 HOURS TO COMPLETE
