Re: Best size end mill for milling perimeter of PCB?
#mill
0.0625 inches equals 1.6mm, I'm going to try, I usually use 2mm.
Vaughn,?are you using vacuum table?
I am close to finishing my smart vacuum table version, for low cost, high vacuum and low flow vacuum pump, I am using a refrigerator / fridge motir, which allows pcb milling even after drilling.
I hope to be successful, it is still necessary for you to be practical and useful
Here a video showing first tests

Re: Best size end mill for milling perimeter of PCB?
#mill
Hi Gerry, I use V point mills. 60 Degree normally, but there are also 30 and 15 degree I think. After milling the board, my mill, mills a border. This I then follow to cut the board?to size. If I mill the surround, all the way through, the board will become detached from the mill bed, so making is unstable, unless you stick it to the bed all over?
Once milled and cut I can then clean up if needed with a file.
Hope this helps Vaughn
Maybe a bit off topic but can someone recommend the best size and type of end mill for milling out the perimeter of a PCB?

Hey gang,
Many long time readers will know I have been around here for quite some time and have been using Eagle and Pcb-gcode to make my boards. For years I have muddled through and made my projects but have always had problems when using copper pours and getting a clearance between various traces etc.
This week, I have a project that is a small board ~.5"x.75" and could not for the life of me get it to "etch". About 50% of the time, it refused to mill out the isolation and yet, make small lines in some fairly close places.
Bottom line after several days of surfing, stumbled across a blog on the net that advised changing the isolation value of the pour. The process to do this is to <right click> on either the polygon or the pour itself if you have ratnested it and this will bring up a dialogue box.
About 2/3 way down, there is an "Isolate" box. By default, this is 0. Change this to a suitable value for your system (I use 12mil). Click apply and you will instantly see the difference. Then click "OK" and your ready to run your ulp or whatever.
Hope this helps somebody else.
I still need that dunce cap as I should have figured this out years ago!

Is it written in what language, C ++?

This has been requested in the past, but it isn¡¯t something I can do at the moment.
The source code is up on , and I keep hoping someone will submit a pull request :-)

No, Pcb-Gcode does not have that ability. It only drills holes with drills and if memory serves me, you cannot mill holes either. It will only allow arcs so if you want a round hole, you have to break that up into two or more arcs.

Not sure if this was in reply to my post but yes. Several cad/cam applications do this. You tell the application what size mill bit you are using and as long as it is smaller than your hole size + tolerance it will drill the hole pretty
much the same way it would create a pocket. It¡¯s slower but if you have a hand full of holes it can be much faster than doing a second setup, third or more bit changes and setups.

Do you think, like you have 0.7mm DRILL bit (good for LEDs, for example), and you're going to MILL a 0.9mm hole for pin-header with it? ;-)

I can see there are a few approaches to GCODE.
Eagle is the obvious first one.
Then Gerber to GCODE converters, I found a few online.
