Ok, this may be a dumb question but here it goes...
Where is the gage line on the spindle? Is it the lowest point? For instance, the profile of my spindle has a bottom face which is closest to the CAT 40 tool holder, then a step of about .200" up to a second face which extends out to the sides.
Would I use the lowest face, closest to tool holder or the second face?
I'm trying to set the tool length offsets in the H registers for the tools in the ATC. The mill is a Hurco VM20 and I really don't want to crash it. It's set up for their conversational programming but will accept industry standard G-code posted from CAM software. I want to be able to use the H values due to collision detection simulation in my CAM software.
The problem is, when G43 is used the tool zero values recorded in the tool setup are substituted with the H values at run time. I need a machine reference on the spindle I can touch off and get a starting value, then insert a tool, touch off at the same Z which would make the difference the tool length, I hope??? Wouldn't this be the value I should place in the H table for that tool?
Perhaps I'm going about this the wrong way, any suggestions?
