The Customer

• Specializes in machining, assembly, inspection

• Serves wide variety of industries: automotive, office, medical, and more

• Currently uses little automation

4Intro Old Project New Project Moving Forward

Project overview

• Parts are currently being produced in a lathe operated by a worker.

• The pucks are put into a lathe twice, machined to precise dimensions, and measured.

• Our task was to automate this process, decreasing cost and increasing part quality.

Ethics and Design Norms

Delightful Harmony TransparencyTrust

6Intro Old Project New Project Moving Forward

Initial design requirements

• Manufacture parts with little to no human interference

• Operate robustly and reliably

• Manufacture 120 parts per hour

• Track dimensions of finished parts

• Comply with safety standards

• All designs are owned by Prefferred Quality Services, not Team07

Project Change

3+ years of production anticipated on the part created by the cell

November 16 the OEM notified PQS that the part will bediscontinued in Q1 of 2018

PQS has assigned a new project to the team to replace this one

New requirements

• New heavier part + how to machine it

• New table

• New electrical hardware and requirements

• No measurement system

14Intro Old Project New Project Moving Forward

Lessons learned

• Scrapped ideas (ex. Gantry robot, two motors for original table design)

• Engineering in industry can be volatile

• Must be able to adapt quickly

• It is important to research deeply as well as broadly

15Intro Old Project New Project Moving Forward

Safety

• Cage keeps employees away from moving parts

• Three Emergency stop buttons

• Safety Relay connects all E-stops and handles emergency procedure

• Safety mat and speaker ensures no one is near table when it rotates.

• Stack lights indicate machine state

16Intro Old Project New Project Moving Forward

Finances

• Cost savings was a important factor for our customer

• With the change of project costs increased significantly and that had to be communicated to the

customer

• We updated our budget regularly and kept the customer informed on all changes

• We saved a lot of the cost by going through several robot suppliers

• We can also save cost in the future by using parts that have long lifespans

28Intro Old Project New Project Moving Forward

Lessons learned

- Working with distributors can be difficult

- Software can have a lead time

- Inter-team communication is important

- Don’t assume things about the customer

- Solid plans make work go much faster

29Intro Old Project New Project Moving Forward

Moving Forward

• Finish programing

• Wire and power all components once drops are installed

• Finish installation of arm and cage

• Begin working through test plan
