Independent Component 1

Step 1:

02/14/2013 6:00 P.M.-6:20 P.M.
I created two dimensional lines to create the shape of my solid model.

Step 2:

02/14/2013 6:20 P.M.-7:20 P.M.
I used my two dimensional lines to extrude my box and create a cavity for the box.

Step 3:

02/15/2013 8:30 A.M.-10:30 A.M.
I added details to make the part machinable. By adding Fillet radii, it creates a shape that will allow me to create machinable tool paths.

Step 4:

02/15/2013 10:30 A.M.- 12:30 P.M.  5:00 P.M.-7:30 P.M.
02/16/2013 8:30 A.M.- 10:30 A.M.  2:00 P.M.- 5:30 P.M.
02/17/2013 9:00 A.M. - 10:00 A.M.  12:00 P.M.- 1:00 P.M.
 Determined material stock size that part will fit in and be able to be machined from. Material needs to be over sized in order to be held in a vise. I then started creating tool paths for the first operation.

Rough periphery cut:

Roughed out pocket:

Finished inside pocket and periphery. Also drilled and tapped cover mounting holes:

Step 5:

02/17/2013 4:30 P.M. - 7:30 P.M.

I then flipped my model over to complete the second and final operation. I milled off the excess material and created a deburring operation to eliminate all sharp edges. I also personalized the box by engraving my name to the bottom. This took 3 hours.

Step 6:

02/18/2013 8:30 A.M. - 11:30 A.M  6:00 P.M.- 9:00 P.M.

 I followed the same steps (drew solid model and created tool paths) to create the cover for my box

Here is the view of my box with the cover on it.

Testing to see if it could be made, no errors were shown on the program.

All this is to create NC coding that the CNC mill can read.

LITERAL
“I, Ariana King, affirm that I completed my independent component which represents 30 hours of work.”
(b) Cite your source regarding who or what article or book helped you complete the independent component
My mentor was the best in helping me complete this component.
(d) Explanation of what you completed.
I created a 2D image of a box with a lid and holes for screws in MasterCam which generated the NC coding after both the model and tool paths were completed.
APPLIED
By better understanding the program, I can better handle the program itself,reducing mistakes, and increasing the speed in which I can generate a program. This helps provide validity to my first answer, which was having a sound understanding of how the specific program a machine programmer is using works. Creating this box allowed me to become familiar with some of the tools of the program as well as how tool programming works.

Independent Component 2 Plan Approval

(1) Write a description of what you plan on doing for your independent study component.


     I plan to do both in process inspection as well as final inspection of machined parts. I will be working with various inspection instruments designed to check  the tightest tolerance of a part.

(2) Describe in detail how you think your plan will meet the 30 hours work requirement.

I will be doing the job of a quality inspector which will include using various type of inspection equipment on various types of parts.
(3) How does your independent study component relate to your working EQ?


 Since my second answer is value machine tool quality over price, doing quality checks will help me better understand as to why tool quality is so important.

Independent Component 1 Plan Approval

CONTENT:

(1) Write a description of what you plan on doing for your independent study component.

Make a few programs in MasterCAM to better aquatint myself with the program

(2) Describe in detail how you think your plan will meet the 30 hours work requirement.

Multiple programs will be made ranging in various difficulties and therefore ranging in times taken to make them

(3) How does your independent study component relate to your working EQ?  

It helps me better understand what program a machine programmer has to work with.

1. How can a machine programmer best produce quality airplane parts in the aerospace industry?
2. Devote himself more to quality than price efficiency.
3.  CMM machines ensure quality, but cheap ones aren't useful at all. Using tools that are made to handle the proper metal. Run proper maintenance on work holdings.
4.  How to select a CMM
5.  I plan to further pursue my second answer by talking to the people in charge of quality in the shop.

On Friday February 8th, you will be going into 2-Hour houses.   In your 2-Hour house, each student will be presenting the following:

• Introduction:  Hello, my name is Ariana King my senior project topic is machine programming and my essential question is How can a machine programmer best produce quality airplane parts in the aerospace industry?
• Sponge: What do you know about machine programming?  
• My first answer is by understanding the programs they use and my second one is by valuing quality over price.
• "According to "How to select a CMM", a proper CMM machine is key in ensuring quality.
• I plan to understand how a CMM machine determines quality by spending more time in the quality department of the shop.
