156B Week 4

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Design and CAD for Ball Clamp is in progress

  • Tests to calibrate CNC machine has not begun 

  • Hardware for CNC machine has been completed 

  • Software for CNC machine has not begun 

  • Gear Train System currently being converted to a friction drive system 

Accomplishments from Previous Week

• • CNC machine hardware finished 

  • CAD for Ball holder is near completion 

  • Acquired lab space 

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Complete Friction Drive design for gear system and begin construction (Jacen)

  • Set up software of the CNC machine (Marshall)

  • Finish CAD of ball holder and begin construction (Aaron)

  • Work with Ian Richardson to create an EDM process for the custom drill bits 

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Meeting set up with sponsor for May 2nd 

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Ian Richardson:

    • Silicon may be an option for an abrasive surface (in person 4/23/19)

  • Professor Ghazinejad 

    • Look into EDM for the custom drill bits (in person 4/23/19)

      • Emailed Ian Richardson to discuss this topic

    • A non-polished surface from EDM may provide the abrasion necessary for the end bit 

  • James Lynch 

    • Research into polishing bits for jewelry (in person 4/23/19)

      • Research has been done into different type of abrasives used to polish jewelry 

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Will the EDM method be precise enough for the drill bits?

  • Will the bits spin at a low enough torque for a friction drive system to be operable?

Resources or Information Required but not Available

• • Need to talk to Ian Richardson about the EDM process.

Schedule

• • Milestone: Begin phycical construction of the system  

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • Spent: $286.43

  • Remaining: $9,713.57

Progress on Report and Webpage

• • Standards section has been completed
