Greetings,


I have read a lot of posts on this forum and I cannot understand the tool table of mach3. Can anybody explain this to me like to a dumb person?

Let's say I have a square part with a hole in the middle through the part the hole is a 20mm H7.
In the cam program, I have 2 tools.
The first tool is a face mill 50mm
The second tool is a 6mm end mill.

And I make a g code with these two tools. The first question appears, does the g-code writes the parameters of the tools into the mach3 program (tool table)
 or do I have to manually put the tools in mach3 and when I make the g code I have to consider which tools are set up in mach3 on which position?

The second question is if I set up the 6mm tool and i want to make the hole exactly 20mm with tolerances H7 I set the second tool diam. Wear a slight +?
So I can then measure the hole and lower the diam. Wear for the difference that I measured?

 
Best regards and thank to all of you

You would load the data into the tool table yourself before setting up the job.

If i wanted a precise hole 20mm dia i would machine slightly undersize then ream it out with a  reamer
