Bob Gillespie's Electronic Notebook
(Text in green font is what I think my contributions have been)
Class
May 12
Class consisted of a get to know each other period
and a discussion of computer aided manufacturing. Mr. Johnson gave us a good
look at his manufacturing
experience as well as asking us ours. We went over class policy.
We toured the lab area. We also went over Alphabet
Soup paper
.

DFM-Design for manufacturability-solely for manufacturing of
part-no end use purpose. We started going into some depth on milling and M code , milling and turning G code. We were given homework
and we spent 2 hours sizing up our lab equipment. Mill: GE Fanuc Controller

Started discussion of Project. We all submitted quick
sketches and veiwed an example.Came
up with jet engine bottle opener/key chain. Tom started laying out a rough
model of this. I researched for jet
engine pictures
to reference for a design.

Received another
from Lou. We went over homework. I went down to lab and went over how to generate code
in the prolight Machining Center. I learned how to export a file from Mechanical Desktop into Autocad and save as a DFX file. Go to
drawing in drop down menu then to export veiw to model space. Close MD to start
AutoCad. Delete all but top veiw. Save as a r12DFX file. Spectrum
Cad-Engraving-Text. Set up the stock size. Open the DFX file. Contour operation
vs Pcket. Ingraving setup Button. Set all. Check on finish machining, does all
multiple pass. Select geometry, select side.Then Go. Save session, save NC. I
attempted to generate a program for a special font and saved it. I tried it on a
mill at work but the code seemed to generate circles that overlapped themselves.

May 29
We received the instructions
for setting up our email accounts and where to log on to. We also got a handout on format
for the research paper. We took our first quiz. I didn't come close to
finishing because I was retracing my steps too much.We were introduced to
high school student, Kevin Norton, who was going to show us how to run the lathes and mills. He
walked us through the lathe program for the PC Turn 55 lathe.
Win
Cam. Load Program. Setup display. All Z is negative.CZ wood out of chuck. First
point is end point of cut. 2d point is end point of cut. Setup tools in
turret. Must tell it to turn on. Clamping device. Green outlines the cutting
parameters. Look from rear of chuck for direction.
At 6:20 we had a meeting.We
went over some responsibilities and discussed what we planned on doing and what
we wanted to accomplish. Material options were evaluated and material
costs were talked about. We were told to come up with at least 5 products so
we all could get involved. The need to purchase actual rings for the
keyrings.Busness card holders were also decided upon. Posters
for the bullitein boards were discussed. I suggested a simple lathe project of
candlesticks. It was accepted. I spent the rest of the night producing the
program for a prototype. I learned how to draw the circles and lines that shape
the piece in the program. We ran out of time before an actual prototype was
produced and the computer errored when trying to save the program.

June 2
Class was started with lab as Mr. Johnson was running late.
I deisgned a new candlestick holder
on mechanical desktop and then exported it to a dxf file. I never got a chance
to try it on the lathe or to use it's geometry to go by when drawing it on the
lathe's program. I also helped Tom with converting his jet engine drawing to a
DXF file for possible machine code generation. Also helped Steve with his
drawing of the USA keychain. Keychains were located online. I emailed Lou the
price list and got a forwared
about Kevin Norton's email. We had another
team meeting in which we talked about our progress. I stepped down as purchaser
due to my confusion on what needed to be purchased. Mr. Johnson decided to do
the purchasing, since noone else wanted to. Homework for Thursday was moved back
to Monday and a test was scheduled for Thursday on the Alphabet
paper and their relationships. Jason gave me his drawing of the fixturing he had been working on. Mr. Johnson showed delivered a presentation
on the development of the Scumbuster
developed at
and alot of
behind the scenes information. I left at 8 pm due to the lateness and missed the
last part of the presentation.
June 3
Got an
from Lou going over a schedule.
June 4
I designed another version of the jet engine
and my new product idea,the Kubotan.
Instead of the candlestick (which in my veiw, needed stock that was too exspensive). I also started a rough web page
with alternate images of possible finished products. My main purpose was to get an idea if this was the right direction. I am going to bring my digital camera tomorrow to try to obtain some images tomorrow to add to it.
Class
June 5
Class started with a quick test and a update on our progress. Steve picked up some stock to help get prototypes going. I showed my web page idea to Lou and it was well received. My camera came in handy taking pics to show the class in action. Pics will be added to the web page soon. I am to get the page ready for uploading to the server. I am going to try to burn a cd to give to Mr. Johnson. After break, I headed to the lab to get started on my kubotan prototype. I was able to run the mill in jog and started shaving a piece of stock down to the appropriate diameter. We stopped working long enough for Kevin to give us some instruction on how to program the lathe with line by line code entry. By the end of class I had whittled the piece fairly close to the final diameter but still did not machine the groves or the detail of where the key ring goes. I made my manufactoring plan. Hopefully it will put us on the right track, so next Monday I can accomplish a finished product by programing. Tom emailed new revison of the drawing of the bottle opener end of the jet engine bottle opener and also the drawing of the engine part.
June 7
I started writing a key to the basic roughing program so I would know how to change it to suit the machining needs for this project. I prepared my resources for a developing topic of lean manufacturing for my research paper and made a coverpage. I also prepared the disc with photos for the web page. The pictures were not good quality because the camera's flash was off. May try to take somemore tomorrow evening. I made appropriate editing, to the web page, due to the lack of production at this time. I will be able to update it as we make progress.

June 9
Tom gave me the idea to allow for extra stock and use a cut-off tool to eliminate the clamping marks from the chuck. That means I have to find a cut-off tool that will fit in the tool turret of the lathe and see if when the piece seperates if it will damage the finish on the product. We went over establishing the origin for the lathe and the different methods that could be used. We also went over the test that was given last Thursday on the Alphabet paper. After break, I gave Mr. Johnson the web page disk and then
I headed to the lab to start line by line programming on the lathe. I put the program in and ran it. It worked good, I just needed to change the coordinates to fit the piece dimensions. I ran very slow to make sure the program was not going to crash. At the end of class I was very comfortable with the program entering process though not as comfortable with the contouring code or offsets though I understand them a considerable amount better and should have a complete proram for Thursday. We received a milling handout.
June 11
Received another
from Lori about putting posters up. I think it is way too early and there really isn't a need to actually put them up, but we should design them. I wrote a basic program for the lathe. it is still in parts and may require a little cutting and pasting.
