Help with G-Code Please!

[widgitmaster]

I have not mastered the G-Code part of my system yet!
I have a project that will make little brass key chain size tags for my Computer Club www.bugclub.org
I have 150 blank tags 7/8" dia. x .040 thick, which were punched out and are dish shaped and distorted. So I designed a fixture which will correct this and allow my spindle access to engrave within a 5/8" diameter area in the center of the tags.
The fixture to hold, straighten and align the tags is finished, but I don't know enough to write the G-code!
I have included an image of the Logo to be engraved, as well as some images of my nifty little fixture! (Made from Low Carbon steel on my rotary table!)

Could one of you with more experience make the code for me, I need to have the tags for the X-mas party at the next club meeting if possible!

Tool will be a 1/32 carbide ball endmill cutting .015 deep.

X/Y zero is in the center of the tag & fixture.
Thanks,
Eric

Eric,

Here it is run thru OneCNC trace image...I didn't spend much time..Also at Z-.015 deep it is a wreck..here it is at Z-.002 deep...

By the way that is one fine looking fixture..nice job..

"X/Y zero is in the center of the tag & fixture."

Opps missed that..Be right back with a new file..Sorry..

Thanks!
Why is the cutter outlining the initial image?
It looks a little too distorded, not sure if I can use it?
I'm sure the members of the club will ***** at me!
Thanks for the quick turn around tho!

The reason it's outlining, is because he used a raster to vector process, and that's how they work. If it looks distorted, it's probably because the image you posted is pretty low resolution. Do you have a higher resolution image you can upload?

If you want single line engraving, someone would have to hand trace it in a cad or graphics program, and then convert that to g-code. There is no simple way to get the results your looking for, I'm afraid.

This is the best resolution I can find of the Club's logo!

Thanks Gerry,

Hey Widgetmaster
As Stated Nice Fixture Just Wondering Why You Didnt Use An Emergency 5c Collet. And Just Mill To 7/8"dia.

The reason is simple, the fixture is designed to flatten the brass tags, as they were deformed (dished) when stamped! When inserted into the fixture with the high side down, the cap press down on the outer diameter with a ring formed into the cap. it makes the brass nicely flat when removed!

Thanks,
Eric


Oh, I never did make the tags for the club, it is still sitting under my router with 100's of brass tags!

I Kinda traced it

[widgitmaster]

Wow!
Nicely centered too!
I will try it out this week, to see how it looks!
Where is the starting point, as there is an access hole in the middle of the fixture to get to the brass?

Thank you very much!
