  1. KhaledAlaassmi and Majid Al Qutaim Milwaukee Electric Tool Slider-Crank Analysis and test

  2. Project Goal • The goal of the project is to determine the offset that provides the best cutting performance for M-18 Sawzall.

  3. Cutting Geometry A=12.2mm= 0.4803 in B= 56.9 mm= 2.24 in C= 19.812 = 0.78 in Pin A C = Offset B XOut C A Angle = z Drive Gear Direction of Rotation

  4. Displacement Analysis of Offset Slider Crank Mechanism Using a Vector Loop Closure Equation:O2A = O2D + DB + BA b c a D

  5. Velocity Analysis Equations

  6. Acceleration Analysis Equations:

  7. Analysis using the “Linkages” software from Robert L. Norton, Design of Machinery, 5ed

  8. Analysis using linkages software • Linkage software was used to make the analysis at 3 different offsets • Offset of 0.78 in • Offset of 0 in • Offset of -0.78 in

  9. Analysis Using Linkages Software • At an offset of C=0.78 in

  10. Analysis Using Linkages Software • At an offset of C=0 in

  11. Analysis Using Linkages Software • At an offset of C = -0.78 in

  12. Designing Slider Crank Using Pro-Engineer Wildfire 5

  13. Pro E Analysis • At offset of C= 0.78 ”

  14. Pro E analysis • At offset of C= 0 ”

  15. Pro E analysis • At offset of C= -0.78 ”

  16. Physical Testing

  17. Physical Testing 2 different offsets 10 runs each offset At an offset of 0.78 in and 0 in The average cutting time for each offset was calculated Test was performed on 2 x 4” wood. The applied load on the blade was 7.4 lb

  18. Physical testing Cutting performance = Time required to cut through 2x4 pine board At C = 0 in, Tavg = 8.9 s, sd= 1.4 At C = 0.78 in, Tavg = 6.3 s, sd= 0.3

  19. Recommendation • Use the Prototype Fixture to Design a Metal Fixture.
