Week 9

Group 6 met up at the beginning of the week to plan out the goals for the week. The group planned out what exactly needs to be done during the week to complete these goals before their deadlines. Members of the group went ot the mahine shop and refined the fork that was created the prior week. They also completely machined the knife part of the assembly by utilizing a bandsaw, belt sander, and CNC mill. They also sent in the appropriate STL files of the casing in to be 3D printed. Certain things must be tweaked slightly so that everything fits together perfectly and then testing can begin to obtain results.

Week 8

During this week the group visited the machine shop several times. The first time was to cut out the fork for the design. This was done using materials from the shop and a band saw. The group then returned the next day in order to shape the fork into a better design. They used a belt sander in order to sharpen the points of the fork and smooth out any rough edges. The group agreed that they would return to the machine shop in the next week to make the knife as well as the casing that will house the fork and knife.

Week 7

On Tuesday of this week the group visited the machine shop that Drexel had with the hope that the Creo models could be made into a prototype. The man at the shop said that Creo models were only useful for making 3D models out of plastic. Unfortunately, the group wants the prototype to be made out of metal. The man at the shop said that in order to make a metal model he needed technical drawings with full dimensions. After this the group began to make the necessary technical drawings in the hopes that they could be completed by next week's lab. If this goal can be achieved, then the group plans to have a functioning prototype by the Week 9 lab.

Week 6

During Week 6, the group met outside of the lab to further refine the details of the design. Members of the group took a visit to the machine shop to get more information on the process of actually machining the prototype and to try to begin to get familiar with what options there were as far as materials and machine capabilities. The entire group met with Dr. Seliktar in order to possibly get some insight on a few specific mechanisms that need to be incorporated into the device. Dr. Seliktar gave an alternative design idea to consider and the group decided it would be best to take up and continue his proposed design. This week will consist of deciding on dimensions, seriously fleshing out details, and possibly beginning to make a prototype.

Week 5

The group met outside of the lab to set a definite plan of attack on everything that is going to need to be accomplished in the next two weeks. Definite goals were set during the meeting with deadlines and team members were assigned different tasks. During week 5, a 3D model was created in Creo Parametric and members of group 6 made a visit to Drexel's machine shop. After talking to someone at the machine shop, they were able to get a better idea of what exactly they need to present to the people at the machine shop for them to be able to create actual parts of the prototype. Members of the group also met with Dr. Seliktar about the progress of our design project.
