Team Vision for Problem Definition Phase

The goal for this phase was to broaden our understanding and narrow the scope of creating the wire spooling and tension sub-system.

Problem Statement

Glass cutting is an important process for companies in the glass industry. There are many different methods of cutting glass that produce different outcomes. A wire saw is a machine used to create multiple blanks at once while maintaining a prescribed thickness. A wire saw uses a single tensioned wire passed back and forth through a desired wire path. To accomplish this the wire is often spooled at each end. Wire saws create straight and even cuts without excessive waste or surface damage. The Meyer Burger DS 264 is the baseline. This machine was originally designed for the photovoltaic industry. Because of this, the machine is overdesigned, costly to run because of power draw, and complicated to run for low volume orders. There are models that are much smaller, but they are only designed to cut one blank at a time.

The goals of this project are to analyze the current wire spooling subsystem in Meyer Burger machine in order to find ways to scale down the spooling process. This will lead to the complete design of the spooling and tension subsystem. This design will be built and tested with thorough documentation every step of the way. The expected end result is a fully functional spooling and tension subsystem. This will be able to be successfully integrated into the overall wire cutting system. The main constraints on this project include: design space allotment, power draw requirements, safety requirements, and cross product cohesion for system integration.

Design Review Q&A

Have you considered the differences involved in changing to a diamond wire?
We will have to consider the additional wear on the pulley and different tensions required.

Is there slurry on the wire when it is on the spool?
Our understanding at the moment is that there is slurry.

What is the purpose of using only American parts?
We need to verify motive for this customer requirement. Possibly component readiness or simply nationalism.
