Abstract:
Boeing Canada Winnipeg (BCW) is one of the largest aerospace composite manufacturers in Canada [1], producing over 500 parts and assemblies for its parent company Boeing. BCW is currently faced with a safety issue related to the use of band saws during a core chamfering process. Band saw operators are at risk of cutting themselves on the band saw blade, as well as being exposed to hazardous core dust that is created during the chamfering operation. Team 24: Honeycomb Badgers Industries has been commissioned by BCW to propose a design to mitigate, or eliminate these risks. The two constraints placed on the project are that it must be completed by December 5, 2018, and that the design must fit inside the BCW building. BCW outlined four requirements that must be met by the proposed design:1.The design must protect the band saw operator from being cut on by the blade.2.The design must minimize the band saw operator’s exposure to core dust.3.The design must function for various dimensions of cores.4.The design must function for various chamfer angles. Through a concept generation and selection process, a blade guard with a pivoting head and a downdraft table were chosen to be developed. The blade guard features a two-part construction with a pivoting head that encloses the band saw blade. The blade guard moves vertically on a track, and rests on the core during the chamfering operation. The downdraft table is located underneath the band saw blade, and it vacuums the core dust into a sink. The deliverables requested by BCW are a 3D CAD model, preliminary assembly drawings, a detailed concept selection process, a detailed design process, and justification for the final design. The project was broken into three phases. The first phase was problem identification and creating a project management plan, the second phase was concept generation and selection, and the third phase was concept development, final deliverables, and closeout procedures. This report covers phase three of the project.
