Shared Vision for Imagine RIT

Best Case Scenario

The best case scenario for team is that we will have our fixture fully assembled, with the controls system we want, and be able to demonstrate all functionality desired. This functionality will be: motors spin at variable speeds based off user input or motion profile, guide rollers match the desired motion profile within tolerance of wire tensile strength, temperature and interlock sensors are integrated within the controls. There will be a means of observing this velocity, as well as confirming that the two motors are in sync. We will have the fixture set up on display and run demonstrations throughout the day. We will have a minimum of two team members present at all times to answer questions.

Moderate Case Scenario

Moderate Case Scenario 1

The moderate case scenario is that the fixture is completed, but without the desired controls. This downfall may be due to the lead time on the enclosure being insufficient to give the electrical engineers time to develop code for the controls. Some complications could be installing the enclosure, mounting the motors, and having the power distribution complete. Finally, the problems that could have caused these complications are that the code itself wasn’t fully completed.

We will be able to demonstrate that the design is mechanically sound, but are unable to demonstrate the level of control that will be required for the final integration into a finished product. We will have the fixture set up on display and run demonstrations throughout the day. We will have a minimum of two team members present at all times to answer questions.

Moderate Case Scenario 2

An alternative scenario is that the controls may have functionality and the power is set up, but the rollers had complications in design and were not ready. This could be because they do not match the frame, couple with the motors, or had to be redesigned within a limited time frame. The demonstration would consist of being able to monitor the motor’s positions given they can be mounted on a frame. We will have a minimum of two team members present at all times to answer questions.

Worst Case Scenario

The worst case scenario is that we are unable to demonstrate a working fixture. Whether it be because the fixture broke, we were unable to obtain parts, or the electrical components did not integrate with the mechanical system, we are unable to demonstrate a working fixture. Regardless, the team will display the progress they have made. In terms of the exhibit, the team is unable to have multiple people present at all times, due to other commitments or extreme unforeseen circumstances. We will have a minimum of two team members present at all times to answer questions.

Elevator Speech

Our team is developing the guide roller assembly of an industrial glass cutting wire saw. It is being designed to replace an existing machine which currently cuts high volumes of glass wafers, but consumes a significant amount of power. Our machine is designed to be more energy efficient and will be used for cutting a small number of parts for ease of production. For our specific project, we will be designing the guide roller portion of this machine. These guide rollers will rotate back and forth simultaneously, causing a wire to move with very high precision. The two guide rollers must speed up, slow down, and move at constant velocity without causing the wire to stretch. After our project is complete, it will be integrated with the concurrent two additional projects, having wiring wrap around the guide rollers and a work piece will drop into the wire array. Future projects will add a slurry containing abrasive particles that is sprayed on to the wire, and a team specifically dedicated to integrating all projects. Overall, our senior design project is the heart of the glass cutting machine and will provide the ultimate framework of this multifaceted project.

Shared Vision for Week 5

Our vision for week two is to finalize the design and begin building of the following components:

Our vision for week five is to:

Due to extended design process and detailed parts, all mechanical components are estimated to be in house by week 8 and ready for build assembly.

Throughout phase 1, we will be working to integrate new MSD I teams into the progress of our team. We will be sharing knowledge from what has been completed thus far.
