156B Week 6

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

• • Jig Inserts for current jig

    • Tested effectiveness of inserts

      • Aluminum inserts do not damage samples

      • Inserts do not damage samples or allow vibrations during cutting

  • Desiccator

    • Redesign to make desiccator smaller to handle more pressure

    • Use thicker acrylic

    • Currently undergoing testing to solve the ‘sealing’ problem

  • Bone sample testing

    • Testing adaptability and ease of use of the jig inserts. Do the jigs actually solve the problem? Does it make the process slower or faster?

Accomplishments from Previous Week

• • Machined jig inserts for current jig

    • Simplifying process by using current jig that clamps to micrometer setup

  • Built desiccator, pulled a vacuum in the desiccator, determined a redesign based on sealing and pressure threshold

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

• • Continue to test different bones to determine adaptability of jig/jig inserts  (Ivan & Brandon)

  • Discuss desiccator design with sponsor (Team)

  • Build and test a redesign of a new desiccator ()

  • Adjust Gantt Chart (Salem)

  • Finish up a 2nd draft of the report (Team)

  • Research Applicable Standards for our Project (Team)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (4.27.16; In-Person)

• • Bone was obtained and approved for testing

  • Advised to come in to test current jig for timing/where to optimize sampling

    • Testing Jig inserts as well

  • Mainly advised us to continue in the same direction (testing prototypes)

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (4-20-15; In-Person)

Risks and Areas of Concern

• • Constructing a design that can maintain vacuum in the desiccator and has fewest penetrations in the acrylic

  • Visibility of samples with transparent material

  • How to assure prevention of damaging samples within dessicator
