Schedule

The schedule for fall quarter mainly revolves around the design of the machine. One major milestone for the project was deciding on the design to proceed with. This involved a decision matrix to weigh out the best options and select the best design. The next milestone for the quarter was creating the first assembly drawings and finishing the part drawings. This is one step closer to the next process of construction and gave a good idea of how the final shape will look. The last major milestone for the quarter was in early December, and it was the completion of the project proposal. After completing the proposal the project was ready to move forward into the construction phase of the project. In order to start the construction on time material was ordered prior to construction in the winter quarter to ensure it arrived before the deadlines.

 

The winter quarters schedule is split into two for the quarter. the first two 6 weeks are for part construction and the following 4-5 weeks are for device assembly. all parts were completed on time for the manufacturing deadlines except the first one. An issue occurred with a 2.5-week delay on the material from Haskins. This changed the schedule drastically, as many additional outside hours were required to get the project back on schedule. A more itemized schedule for the whole project is shown below in Figure E1.1 and 1.2.

​

Testing is the third and final quarter for the project. Testing will consist of 3 separate tests including feed rate, housing deflection, and shaft deflection. These three tests will ensure that the project is operating correctly. The schedule for this quarter is broken down into three sections the first third of the quarter was spent on testing, the second spent on presenting the project at source and the JCATI symposium, and lastly the final weeks are cleaning up the materials for the project and consolidating all the files into one location.

Budget

 During Fall Quarter it was found that the most expensive and hard to acquire parts for the project was the plate steel for the housing plates. The 3/8” plate is heavy and expensive, the cost for the 1 sheet required was around $650. This was ordered prior to construction winter quarter to ensure the material was present for the start of winter quarter. Additionally, the bar stock steel was procured from Haskins Steel as well and this will cut down on shipment costs. The manufacturing of the aforementioned parts took place at CWU cutting down on total cost. All hardware for the housing was from CWU/Fastenal and helped reduce cost by using pre-purchased hardware. The labor for the project was calculated at $25 an hour. Although the labor is not paid for this project it still is a required cost for all projects and must be analyzed. The high number of labor hours is connected to manufacturing of the product being all in house at CWU.
