Abstract/Summary
Pedestal grinders are one of the most common machines found in machine shops today. The current industry standard for mounting a grinder is on a fixed single pillar, cast iron pedestal. A fixed pedestal allows for no vertical adjustment for shop users of different sizes and is a safety hazard. This report further defines this problem and proposes an iterative design process to meet the needs and wants of the customer. The adjustable-height pedestal grinder stand Senior Project team used this problem and design process to successfully complete the project within the allotted time. The first major deliverable and milestone covered is PDR or Preliminary Design Review. To prepare for this, the team performed brainstorming and ideation sessions which helped them properly define the problem and determine the feasibility of solutions to the major functions of the stand: actuation, kinematic structure, user interface, and locking mechanism. The team utilized weighted decision matrices and Pugh matrices to select a final system level design concept. For the next major deliverable, IDR or Interim Design Review, the team utilized CAD modeling software to demonstrate the construction and overall function of the selected design concept. After IDR, the team began conducting analysis on the electrical and mechanical systems of the stand. They also sourced material and components while tabulating costs into a bill of materials. Next, the team crafted a manufacturing plan which describes in detail how each component of the stand will be machined and assembled. The team then designed a testing plan for the grinder stand to ensure that it meets the specifications outlined at the start of the project. After Critical Design Review, or CDR, the team manufactured the custom components, assembled the stand, conducted tests, and drew design conclusions. The timeline of the milestones, as well as the planned actions for the team, are described in the Gantt chart in Appendix L.
