Lathe Tool Tip Radius

[clarkea1]

Hi

Some of the tools I use aren't standard, so I define custom tools for them. The theoretical 'sharp' tip point of the tool is set at 0,0 and then I se the tip radius value to 0.1 as per the tool. However, when I run the machine the parts come out 0.2 over size. This can be seen in the code as well. If I set the tool nose radius to 0 it works fine.

Any ideas what is going on?

Cheers

Dave
