We have the option in Pro of using either "parameter" tools or "solid" tools. Parameter tools are the quick way, as you only need to define the values of the tool (for a milling tool, they are cutter_diam, length, corner_rad, etc). The better and more intensive way is to use "solid" tools, which are actual solid models and assemblies representing the tool geometry. This makes visualization much better in both Pro and Vericut. We always use solid tools in milling for this reason.
Now that we are getting into turning with Pro, of course I also want these tools as solids. The problem is that ProE is treating these tools differently than parameter tools. If a parameter tool is used, it is converted in Vericut with the control point at the intersection of the side and end angles, not the center of the nose radius (this is what we want). If a solid tool is used, it is being output to Vericut at the center of the nose radius (this is leading to excessive material removal, equal to the value of the nose radius).
Strange thing is that if I have a parameter tool loaded in Pro's tool manager and it is NOT used in the turning sequence (an extra tool, basically), Pro ALSO converts this tool based upon the center of the nose radius. If I use it in a sequence, it gets converted by the intersection of the angles.
Go figure.
Has anyone ever dealt with this problem and come up with a solution short of hand editing the Control Point values in Vericut's Tool Manager?

I'm pretty sure that in Pro/E when we are programming for turning, we drive the center of the radius (we have the TIP csys at the center of the radius).
Everything seems to come out correct for us in Vericut because we are driving the center of the radius anyway, there might be a setting in Pro/NC that changes the driven point on the tool, but I think the default is the center of the radius.
From a Vericut perspective, I think you could go into the tool manager and move the position of the parts so that the driven point is at the position you want, it would be a lot of work, but I think it would work. Turning tools don't help me much at all using Vericut integrated with Pro/E because pretty much all of our turning tools are not simple extruded or revolved parts, we have some funcky tools from Kennametal, and I've managed to get solid models from them and just import the STL files, so I have a separate tool list that is used on several of our machine, a master tool list if you will, that kinda takes care of any/all situations, I just make sure the tools are set up correctly there, then I specifically point Vericut to that master tool list before I start my simulation.
Hope this helps,
