• Proj ect: Designing and prototyping a steel reinforced

hose cutting machine

• For whom: MFP Automation Engineering

Factory Reel size #4- #20 S teel Reinforced Hydraulic Hose Technician measures hose and marks it, double checking his measurement Technician pulls hose to saw and cuts hose The cut hoses are then blown-

• ut from both

sides to clean insides Mark hoses for fittings – fittings must be on a hose a specific length Install fittings by hand (only hand tight) Tighten fittings (hydraulic) Crimp Fittings Attach Caps on ends of crimped fittings Wrap PTS Tag around portion

• Average Time S

aved per Hose Length is 15 seconds

• Almost 2x faster!

Budgeting BOM

6

MFP allowed us lots of wiggle room with our budget, which was mainly due to the costly price

• f some components needed

=$7,000 =$9,360

Why the Large Gap:

• Heavily underestimated expense of Conveyor S

ystem

• Conveyors
• High Friction Belt material
• Custom Motors

Overall Cost of Conveyor S ystem = $5,267 MFP did not want us to extend beyond $10,000 We went over our original goal but succeeded in staying under $10,000 Planning Opportunity Introduction Conclusion Design

Cutting S ystem

Implemented S ystem: Bring the hose into the saw Merits:

• Allow hose to bend, causing no pinching
• Increase lifecycle of saw blade
• Creates cleaner cut
• Adaptable to various hose sizes

Discarded Alternatives:

• Bring the saw into the hose
• Guillotine

Feeding S ystem

Implemented S ystem: Conveyor Belts Merits:

• Maximize surface area to reduce slippage
• Capable of variable hose sizes
• Variable feeding rates

Measuring S ystem

Implemented S ystem: Rotary Encoder Merits:

• Accurate and Precise
• Less tolerance stack up
• Bi-directional

Discarded Alternatives:

• Using conveyor run time

Control S ystem

Implemented S ystem: PLC S ystem Merits:

• Industry standard controller
• HMI feature
• Easily upgradable
• Robust S

ystem Discarded Alternatives:

• RaspberryPi
• Arduino

S pool Mount

Discarded Alternatives:

• Rotary Dampener
• Clutch Bearing

Used a pneumatic cylinder with a custom head as a j am break, to prevent unwanted rotation.

Proj ect S tatus



Waiting on ordered parts (VFD, S aw Motor, Conveyors, Rotary Encoder)

 Rotary encoder delayed from April 30 to May 14



All components fabricated, waiting for conveyors to mount with proper alignment



Debug Code when Conveyors Arrive



Test will be done with timed signal as proof of concept without encoder. Planning Opportunity Introduction Conclusion Design
