Sorry if my question seems trivial but I am new to CNC machining and I have limited experience with machining period. I am a welder by trade who now runs the welding portion of a small machine and fab shop. I have CAD experience so the owner asked if I'd be interested in learning BobCAD and eventually work toward being able to program the 2 CNC machines we have that hardly get used. Don't get me wrong our machinists are awesome but we do a lot of repair work and not a lot of production work but occasionally we will so the CNCs would be a huge benefit. So here is the problem I'm having..... We have a Haas VF-2 and I wrote a g-code for a part but I have been unable to access the tool offset parameter the D portion of the g-code. I have the book from Haas and although it touches on the tool offset it isn't very clear on how to change the value for this parameter. The book is also doesn't explain what 01-50 (I believe that is the scale) represents in relation to the amount of offset. In the book is a test program that specifies a .250 end mill with a D-01 (I believe) which would be a .200 offset. How much of an offset would 02 give you? Or 03 or 09 and so on.
Sorry if this question isn't presented correctly but understand I've basically been handed a basket case and asked to make something of it. I've been teaching myself to write g-code, learning the BobCAD software, advancing my knowledge of general machining........ in a nutshell I've been busy busy busy..... and my mind is frazzled. Any help would be greatly appreciated.
Thanks in advance,
Chris
