2. Outline Overview Measurements Current Design Budget Next Steps Questions

3. Overview Sponsored by DynaTorque in Muskegon Designing a device to accurately measure critical dimensions of their machined gears Must measure five critical dimensions Obtain measurements within.003 of an inch Save time and money

4. Measurements: Part 1 Outside Diameter

5. Measurements: Part 2 Throat Diameter Whole Depth

6. Measurements: Part 3 Twist

7. Measurements: Part 4 Addendum -Calculated using pitch diameter and throat diameter Pitch Diameter -Calculated using whole depth and outside diameter Lead Angle -Calculated using pitch diameter the gear and worm along with number of teeth

8. Current Design Gear held by a pair of V shaped blocks Constructed such that center line is known Automated low point detection Strap to hold gear and worm gear

9. Current Design Continued Cost effective Hopefully meet time requirements Appropriate Able to accurately take all measurements

10. Budget Big Ticket Items –Height Gage –Construction Materials –Motor and Ball Screw Additional Costs –Digital Indicator –Power Supply

11. Next Steps Design automation controls Build proto-type Revise design Finite element Analysis

12. Concluding Remarks Current design fulfills requirements Kept on schedule On target for a successful project
