CNC Custom Drink Coaster Design & Manufacturing Challenge

Design Team:

– Matthew Wykoff & Kristen Ward (Engineering Instructors & Curriculum Innovators)

– IED & CIM Spring 2014 Student Designers

– Mel Radford: Senior Research & Development Engineer Advisor

Project Timeline: 1/27/14 – 2/21/2014

Client: VAOE Stakeholders

Designers: VAOE Students

Problem Statements:1. VAOE needs corporate support for more advanced technological

training and resources in order to help prepare our students for 21 st century careers.2. Project material costs for 4” x 4” x .5” per student equals approximately .41 cents per piece.3. VAOE students currently have limited or no technology skills relative to computer aided design and computer numeric control

programming, 3D rapid prototyping & milling machine operation necessary for entry level positions in a manufacturing environment.

Solution Statements:4. Engage VAOE corporate candidate partners in Engineering Education reform by extending

invitations to our regular advisory board meetings.5. Raise funds as a VAOE student leadership team to purchase advanced technology and training resources

relative to basic and advanced design and production experiences.6. Train students how to design and manufacture a basic drink coaster prototype using classroom resources

such as PLTW curriculum, CAD & CNC programming, 3D printing & milling machine technology in 4 weeks.7. Strengthen stakeholders and corporate candidate partner relationships by gifting custom prototypes

to show appreciation and evidence of student skill exposure & performance.

Constraints:8. Must be designed < W=4” x D=4” x H=.5” volume of space9. Must be made out of cost and quality efficient material (i.e oak)10. Must be a simple design (↑Complex Shapes ↑Cost)11. Must be safe for all users (i.e. no sharp edges)12. Must be completed for NC-TSA Regional Competition Date (2.21.14)13. Design process must be documented on PowerPoint
