Presentation Transcript

  1. Team Clean Cut Sponsors: Composite Decking Blade Team Members: Brian Norman Craig Daniels Ted Florence Wesley Anderson Vince Mayer Advisor: Jay McCormack

  2. Project Definition • Primary Goal: Force Analysis Apparatus • Measures force as a function of blade position • Will allow different blades to be tested • Use data to develop an empirical model for the cutting of composite decking • Relocatable to Bullet Tools

  3. Project Definition • Secondary Goal: Composite Decking Blade • Develop a blade that will reduce the blow out phenomena seen in composite decking by 50%

  4. Projected Time Line for 2011 Semester

  5. Expenditures • Total Budget: $700 • Cost as of this presentation: $0 • Purchases to be made: • Linear potentiometer • Strain gage adhesive • High Precision Resistors

  6. Background • Reference Book • The Science and Engineering of Cutting: The Mechanics and Processes of Separating, Scratching and Puncturing Biomaterials, Metals and Non-metals By Tony Atkins • Experimental Design • Decisions • Strain Gauge Placement • Linear Potentiometer Design • Data Acquisition

  7. Experiment Specs

  8. Experiment Specs Con’t

  9. FBD & Stress Analysis

  10. Experiment 1

  11. Crack Formation

  12. Experiment Design 2

  13. Shear Moment Diagram

  14. Experiment 3 SATEC T5000

  15. Problems/Concerns • Accuracy • What will it mean? • Will the data be useable • Difficult to model blade as a whole • How will it help us solve our problem?

  16. D2 Tool Steel 154 CM Stainless Steel Bohler N680 Stainless Steel This material has the addition of vanadium and nitrogen for increased strength 440 CC Stainless Steel High Chromium

  17. Pros No Blowout Cons Heavy Noisy Lots of Saw Dust Bench Marks

  18. Redesign Specs

  19. New Potential Designs • Sharper Blade Angle θ<18° • Flip Blade around and use angled cut • Change Shape of Blade • Guillotine • Curved blade • Dual Blades

  20. Blade Design Angled
