Team Vision for Build & Test Prep Phase

Phase 5 Team Plan + Milestones (online)

Phase 5 & 6 Team Plan

Milestones MSD II

What is our plan?

• Finalize structure shape and dimensions
• Mold mounting method
• Benchmark heating system
• Design heating system mounts
• Meet with Prof. Stevens to discuss heating and cooling system
• Finalize mold design
• Design part ejection method from the mold
• Follow up on budget increase request
• Meet with The Construct to discuss vacuum forming capabilities
• Meet with the machine shop to discuss welding and machining capabilities
• Order materials for structural frame

What have we completed?

• Received electronic components
• Met with Michael Buffalin at The Construct and discussed plastic laminate constraints
• Updated mold design to create a 12” x 12” x 1/16” plastic sheet
• Met with Rob Kraynik about machining of structural frame
• Updated structural frame design from Rob’s feedback
• Began machining a prototype mold to start testing of plastic melting and cooling
• Budget increase request was approved for a total budget of $1150
• Updated BOM
• Updated risk assessment
• Planning on going to Klein Steel on 1/25/18 at 2PM to pick out raw materials
• Planning on meeting with Prof. Stevens on 1/25/18 at 9AM

Working Test Plans can be found here.

Materials, Procurement and Budgeting

Current Design

Our current design has undergone the following changes following a meeting with Robert Kraynik from the machine shop on campus.

• Legs and top vertical frame members are now one piece.
• Some horizontal members undergoing compression or expansion were strengthened from 1/8" wall thickness to 1/4" wall thickness.
• The corner gussets (braces) were changed to triangles cut from flat bar steel.
• The bottom mold support was flattened to allow an even distribution of forces.

Risk and Problem Tracking

A working Risk Assessment file can be found here. The primary source of risk mitigation has come from the budget increase for our project:

• R9 - Insufficient funds to purchase all materials.

An additional risk was added concerning the cooling of the system:

• R33 - Cooling system is not designed/implemented.

Design Review Materials

• Previous meeting notes.

• Review Feedback

Plans for next phase

• Testing
  • Testing of mold machining
  • Testing of prototype mold
  • Testing of aliment system
  • Testing of heating system
  • Testing of electronic system

• Designing
  • Designing of ejection systematic
  • Designing of cooling system (could prove non-feasible)

• Building
  • Structural build
  • Prototype mold build
  • Electrical system build
  • Prototype heating system build
  • Ejection plate prototype

• Ignacio Martos - Phase Plan
