Re: new pics, sherline stuff

hey alan!
thanks for the nice comments! I hope to put up another of a head
button (later today) I made for my radio control heli before all of
this cnc stuff got started :) Its my first real part that I made on
the lathe and mill. I think its great for all of us to share what can
be made on cnc. The fan was made out of a 10 year dream of mine to
make a "fan" as my FIRST CNC project. I had to make it before moving
on! It was QUITE a project (and probably not the best for a
"beginner")- just trying to figure out how to use CAD, the cnc
software, setting up and mounting pieces took sometime! Not to
mention, cutting speeds, how deep to cut, and so forth! Its been
around 3 months now, many late nights (inbetween school), lots of
reading, and MUCH experimenting but I finally feel as I have some idea
of what I am doing. The fan is made "just for fun". It took me 3 tries
as you can see from one of the pics to cut it out right...its still
not perfect but heck its done!! I used DeskNC to cut it out and ace
converter...I did not use the "close enough value" at that time so
there where many extra useless Z steps (use the close enough value).
Well after about 6 hours of cutting (all 3 fans) and 1.5 cans of WD-40
I have learned a lot!!! :) From drawing better in CAD (since I do not
have cutter compensation) to setting up the machine, getting the chips
away better, using shorter endmills, learning G-Code, to using less
WD-40 heheheeee! The first fan came out to thin and cut through. With
the second fan (and since I only had a 15 min demo version of DeskNC)
I would go back into the .txt file and count the number of lines the
machine had run and then delete them...I would then rerun the program
and reload the remainder of the file (not a fun way to do all of this
stuff)..so as anything would have it, I messed up one line and the
cutter when off course...lesson learned! Don't mess with the G-code
unless you really know what your doing! The third fan was cut the same
way but I did not add and deleted only lines I knew of. I have figured
out a way to simulating "cutter compensation" in my CAD by drawing a
drawing and then scaling it either up or down by the cutter diameter
used..I have not tired it yet but it works on paper. Thanks again, I
hope to see some of your pictures also!
