What is the value of d1 ?

PM:

D1 = zero. That's why it works. <g>


Doh!!!

Where I program cutter comp a value of zero then result is an undercut by an
amount equal to 1/2 the tool dia.

Hopefully if you are caught the cutter comp police will only fine you...


PM:

You mean I've been taking a shortcut & breaking the CRC laws for over a
decade? I hope those fines aren't retroactive.

Perhaps it's just an artifact of Gibbs. Here is an example of how
Gibbs' machining markers work:

=================================================================

Now a quickie explanation about the Machining Markers above. The blue
arrow is the direction the tool will go (you can choose backward or
forward movement), you highlighted one of the three circles, they tell
the tool to either go on the outside of the geometry, the inside of the
geometry, OR centered on the geometry. The white round marker is where
the toolpath starts, and the black round marker is where it ends. The
square black & white markers are the particular section of the geometry
chosen to start on. The red line it the toolpath, the purple like is
the geometry (it is purple, right? I'm color blind and it looks like
dark blue to me)
=================================================================

Like I said, this toolpath can be done with CRC ON, or OFF. It's makes
no difference whatsoever, unless there is an entry in the comp.
registers in the control. IF there IS, then choosing CNC ON will alter
your tool offset by what's in the "D" register.

I wonder how many people actually put diameter/radius offsets in their
controls. Sounds like a survey in the offing. <g>
