RE: [CAD_CAM_EDM_DRO] Basic questions

Gordon,

I can help you.

A vacuum hold down would do what you want. Most use a piece of MDF for the
top. The vacuum will pull through the MDF. You would be cutting slightly
into the MDF.

Vectric www.vectric.com has a number of programs that can help you with
converting your drawings to internal files. Programs like Cut 2D at $149.00
will allow you to generate the G code.

If you have questions I would be glad to help.

Bob Campbell

Subject: [CAD_CAM_EDM_DRO] Basic questions

Hello, I have been lurking on this list for sometime and I have a couple of
dumb questions that I hope someone can answer for me or point me in the
right direction. I am very close to buying a DIY CNC router kit like the
blueChick. I have read a lot about the machines and control software but my
questions are pretty basic and most likely dumb, here goes:
1.) How do I hold material on the table? I will be cutting thin wood,
liteply and balsa wood. I will be cutting through the wood to cut out parts.
My question is how do people hold the material in place and what do you put
under the part you are cutting to make sure you do not cut into the bed of
the machine.
2.) I have old drawings with patterns for formers (mostly from model
airplanes) that I would like to convert to gcode files to enable cutting the
parts. Is this possible? If so where can I learn more about the process. I
hope I can scan them in and then convert them to gcodes.

I hope these questions are appropriate for this list and appreciate any
input.

Thanks!

--Gordon
