You have just been hired by tooth, the whole tooth, and nothing but the tooth©. There have been several complaints that the dental chairs the hygienists and dentists use day to day are not adequate. You will be designing, manufacturing, and, with NX, building a new dental chair to be used by the dentist or hygienist, not the patient. It must be able to glide easily across the floor, it should not obstruct the dentist or hygienist's ability to perform their job, and it must be ergonomic. You will be undergoing this project from the roles of the design engineer, materials engineer, manufacturing engineer, and the industrial engineer. This process will end up producing 100,000 of these devices.
Design engineer duties
- The chair should use enough legs to ensure stability.
- The chair should be able to adjust for the different heights of operator. (You do not have to design hydraulic system)
- The top surface should be a 360° rotatable shape of your choosing based on ergonomic data
Materials engineer
- What materials should the individual components be made out of?
- Will a certain part wear out over time?
- What type of intended use would be bad for a certain material?
- The raw material cost per part should not exceed $100.00. Calculate this with material weight -vs - cost.
Manufacturing engineer
- Now that the materials are selected and the part has been designed, it is time to determine which manufacturing processes will be used to create the parts
- Based off of the manufacturing process you choose, what machines are needed? How much will that cost for startup?
- Make sure you choose processes, materials, and tools which can withstand creating 100,000 parts.
Industrial engineer
- Decide how you would set up the factory that produces these devices in such a way to maximize the output. Be thorough in describing why you chose what you chose.
o BIG bonus, use arena to simulate how long it would take to create one of these parts based off of estimated times for each machine etc.
- How many employees would it take to operate this factory?
- How much does this add to the cost of producing 1,000 of these parts?
Your final report should include the following
o Should include an NX drawing showing
- Table of contents
- Design study
o Covering all of the points from the design engineer and anything else you want to add
o Include all relevant NX drawings and assemblies that support the points from the design engineer.
o Covering all of the points from the material engineer and anything else you want to add
o Covering all of the points from the manufacturing engineer and anything else you want to add
o Covering all of the points from the manufacturing engineer and anything else you want to add
- Discussion and breakdown of the overall cost of producing 100,000 parts
- Assembly instructions accompanied by NX drawings which explain how to assemble the device
- Conclusion
- Bibliography
o Where did you get the information regarding material price, strength, etc.
