Thanks Graham
I think with all of your help I getting it to work.

Thanks again

P.S.  What's the best book or cd to learn G Code
        I'm not an idiot but I have been called a monkey before

Thanks It's starting to make sense.
When I say wear, what I think I should be able to do is; if I need to cut
.002 more off a side I "in theory" should be able to go into "tool wear" and
put in -.004 and that should cut .002 more off the part.
? How would a simple code look like if I wanted to use a 3/8" endmill 1" long to cut a "2 inch circular pocket"  .500" deep
(so I guess the cutter would be on the right if I was cutting cw)
I need to know this so if I want to change to a .5625 cutter I won't have to redo the whole program.
Please let me know,
Thanks,
Brian

Hi thanks for the reply.
No when I say no tools I mean no tools.
I started using Mach 3 last year to cut 3 specific parts
on a dedicated machine (lathe) so I had 2 tools set up and just wrote the program to
work.  Now I converted a knee mill to cnc and I will change tools manually but I need to
learn how to set up basic tools and be able to use "wear" to change the part dimensionally
when I cut it.
Please, If you can help me with this that would be great. The manually really doesn't make
too much sense
Thanks,
Brian

also  how do you write in a cutter in the code so you can just change the diameter to cut a different path?

Using Mach 3 mill.  I have a G Code program that has been written using no tools.
I need to take off .010" off the outside of the shape I'm cutting.
? What's the easiest way to do this.
Please help.
