Cnc For Complete Beginner

Good morning.

One day in the none too distant future, I should like to try CNC machining with a small mill. The trouble, is: I am confused about the processes involved. I have been doing some searching, but have not found anywhere that has a simple, idiot-proof overview of how to start CNC work. There seem to be programmes that convert CAD straight into code, CAM programmes, G-code software and, the nicest seeming, conversational CNC (?).

I have looked at the CNC Cookbook website, but found that just as confusing as it seemed to offer so many options that I could see where to start.

I am happy about the actual physical machine (I am thinking about a CNC-converted Proxxon MF70 mill), but should appreciate some basic guidance on how to start learning the operation of it. Can anyone suggest a suitable site or book? I have no experience of CAD, but have coded in the past (VB, VBA, HTML and very rudimentary C++).

Thank you.

James.

James, check out "Basic CNC" written by Jumps4 (Steve) located as a sticky, in the "CNC in the home shop" section on this site.
I think that is it the best write up and is what got me started into CNC. Bob

I have read the thread above, as suggested, and am slowly getting a clearer idea of CNC.

I have looked around for some software to try, but, again, am getting confused. Initially, I am looking for free programmes with which to practice: I do not have a CNC machine yet, but do want to learn the concepts first.

I currently have no CAD, CAM or G-code programmes and am uncertain which is the simplest route to take initially or which programmes are the easiest to learn. Does anyone have any suggestions?

Thank you.

James.

+1 on watching Steve's videos. You should also read his CNC build thread on this forum. Lot's of useful information there. My mill build is a copy of his and works great.
