Project Charter:Below is the official project charter for the MHPSA STEM Elecrode Redresser Machine. This Charter signifies the start of the project. The signatures required are those of the sponsors, the lead engineer at MHPSA, the academic advisor at the UCF’s College of Engineering, and as the signature of the project managers (Stategic Samurais). This Charter is an agreement of work that details the scope of the project. Changes to the scope will have to be done through a change request form (see page 5).

Project Scope Project Mission:The purpose of this project is to create a machine and establish a process to resurface titanium electrodes when they wear out during electrochemical machining (“ECM”). The machine will be used by Mitsubishi-Hitachi Power Systems America at their Orlando branch for their Shaped Tube Electrochemical Machining (“STEM”) Process. No alterations will be made outside of the intended use of the machine. The STEM machine is being created to alleviate reliance on outsourcing the electrode resurfacing to vendors. Not having to rely heavily on vendors will save time and money while increasing process confidence when manufacturing gas turbine engine components.
Deliverable:Strategic Samurai’s have been hired by the Engineering Senior Design group to help them create a project plan and manage the delegation of tasks during the designing of the MHPSA STEM Electrode Redresser Machine.
Although Mitsubishi-Hitachi Power Systems is a Japanese company, the project plan will be completed in English.
Requirements:The STEM machine will be able to redress titanium electrodes with a nonconductive coating with diameters between 1.5mm-1.75mm at a 30-degree angle.
Limits and Exclusions: The STEM machine will not be able to fix broken electrodes and will only redress titanium electrodes. Also, this machine will not be able to redress mass quantities.
Project Priorities:The triple constraint that we will be prioritizing throughout the duration of this project are scope, time, and cost in order to track the progress of the machine.
Cost has been accepted since certain parts that are required to create this machine will be purchased from vendors with set prices. Also, when referring to cost, no strict budget has been set by the project sponsor. Whatever costs the machine retains, will be accepted. Since this machine is being designed to reduce dependency on external resources, the scope must be optimized in order for the team to create the most efficient machine. Time is constrained (inflexible) because this project has to be completed by a deadline that has been set by the College of Engineering for graduating seniors and is a non-negotiable factor. The table below summarizes the project priorities.
4
Project Change Request Form:The project change request form is included in case a stakeholder wishes to make any changes to the project. Since this machine has to work flawlessly, scope will be enhanced and in order to make changes, there has to be a formal method of action in place to keep track of the changes and get approval from necessary stakeholders.
5
Key Assumptions: Below are the assumptions that were made to complete the project plan. These assumptions shaped the decisions made throughout the plan.
All electrodes that will be redressed are in good enough condition to handle the process. Mitsubishi-Hitachi Power Systems has space on the manufacturing floor to accommodate the
machine. Once a process is implemented, a worker will be assigned, by MHPSA, to use the machine. All approvals can be made in one day. Engineering team members work four days a week and 30 hours a week per head. Engineering team members are employed by Mitsubishi, they have other tasks that have been
allocated to them different from this project. Hence, we know that they do not commit all of their man hours to this project. Instead, we are assuming that three out of eight hours of a work day are devoted to this project.
None of the overhead costs such as existing machinery and operations will be included in the budget for this project.

Network Diagram: The network diagram is a visual representation of each work package in order of completion. This is a useful tool when identifying predecessors and the critical path.
19
Critical Path:The critical path starts at activity 1.7.1 and travels through activities 1.7.2, 1.7.3, 2.1.0, 2.3.0, 3.6.0, 3.7.0, 4.1.0, 4.2.0, 4.3.0, 4.4.0, 4.5.0, 5.1.0, 5.2.0, 5.3.0 and ends at activity 6.0.0. This is the critical path because it’s the longest path on the network diagram; it contains zero slack time and therefore cannot be crashed. The total time it will take to complete the entire project is 105 days. The activities on the critical path consist of writing the machine code, ordering material and machine parts, assembling the enclosure and then the entire machine, conducting the experiment and finally, releasing the machine to production.
Direct Cost Estimates:Each work package has been analyzed to identify total direct costs. Indirect costs have not been accounted for because this is not the responsibility of the Engineering team to calculate and include. Most of the costs incurred come from labor. The total cost for this project is about $22,000.00.

Quality Management Plan:Quality for this project is defined by the Engineering Senior Design team in conjunction with the standards and specifications set by Mitsubishi Hitachi Power Systems America and engineering specification drawings published by the vendors of the parts. The purpose of this quality management plan is to define the specifications needed for the components of the machine, as well as define overall quality of the completed machine’s ability to redress worn electrodes.
34
Raw Materials & Outsourced Parts:The chart below details raw materials and outsourced parts, the method of testing they will undergo, and the specifications needed to pass the quality check. The qualities detailed will assist in assuring the overall quality of the completed MHPSA STEM Electrode Redresser Machine. If quality is not maintained with these materials and parts, they will have to be exchanged and retested to ensure function.

Final Machine Operation: The next chart details the qualifications needed at the completion of the project. The specifications will be for the final dimensions that will be accepted when an electrode is put through the machine. These tests will be done on the final MHSPA STEM Machine and the results will be analyzed using optical microscopy. If Quality is not reached in this testing, the machine will need to be analyzed and specifications will be changed at the discretion of the Senior Design Team until ideal quality is reached.
