Project DefinitionThe desired glass cutting machine is a device that will accurately cut several blanks of glass using a diamond coated wire. The energy efficiency will allow for it to be used for low volume production and will consume less power during operation. The current model, the Meyer Burger DS 264, draws too much power, takes too long to start up, requires temperature control, and utilizes an undesired cutting medium. It is also limited in range of motion, thus limiting the cuts that can be made.
The goal of the glass cutting machine project is to define, develop, and design a complete wire saw machine. Improvements must be made to the current design to create a more energy efficient machine and a smaller form factor; however, functionality should remain similar. A functional device that meets all customer expectations and is in compliance with Intellectual Property laws is the expected end result of this project. Due to the complexity of this project, it has been sub-categorized into several MSD projects. This specific project focuses on work piece movement for the glass cutting machine. The key deliverable is to create a standalone fixture for work piece movement that will be combined with additional projects in the future.

Critical Design Challenges
- Ensuring that the wire does not break during operation (or at least minimizing the possibility that it would).
- Allowing for a large variety of different glass materials and sizes to be cut.
- Properly interfacing with the geometries and controls of the other sections of the machine (P16601 & P16602).
- Minimizing power consumption.
- Reducing set-up/tear down time.
- The fixture must be able support the same size work piece as the Meyer Burger DS 264 but the machine must be smaller
- The workpiece movement fixture must align with the wire movement fixture and guide rollers
- Cannot exceed maximum power for this fixture
- Must have signal ports that can be used to communicate with other fixtures
- Must have a control interface with which the stand alone fixture can be operated (design to be integrated with whole system)
- The machine should be designed so that it cannot harm anyone in the event of a major malfunction or failure (guarding - OSHA standards). The current Meyer Burger machine closes off all moving parts while the machine is on.
- Maintain minimum linear speed of 0.1mm/min
- All 3 subsystem projects (16601, 16602, 16603) need to be able to interact with each other.
- Emergency stop signal, once triggered, needs to be able to completely stop all 3 subsystems.
- All subsystems need to be sized so they fit together in a way that allows for glass cutting.
- Some design criteria depends on what the teams decide.
- Dropping the ingot would cause damage both to the ingot and the machine.
- The equipment needed to build the subsystem may be expensive.
- The completed system cannot use too much energy.
- American parts must be used.
- Team has overlapping schedules, hard to find a time when everyone can meet outside of scheduled class.
- Emergency shutdown must completely stop all moving parts in the system.
- Moving parts must be enclosed to ensure the safety of operators and bystanders.
- Any coolant that is used must not be able to contact operators or bystanders during machine operation.
Environmental and Societal Risks:
- Low energy consumption.
- Do not pollute the environment.
- Intellectual Property issues with patents from basing design off existing machine.
- Not having a clear and decisive direction that we are taking the project, or not having everyone on board with the project direction.
