[QUOTE="CoolHandLuke, post: 292281, member: 4850"] thats why i left that lab. i got feedback things were wrong but i was tightly controlled to NOT modify the CAM or machines for fear of voided warranties and broken machines. so fine you get crowns with wrong bites and thats the and of the story. what i can now prove beyond reasonable doubt is that the CAM is the biggest source of problems for people doing CADCAM. its a little field of data science called Metrology. download free Metrology software for most purposes on a free restricted Trial basis if you like. here is a Metrology scan of a bridge, the dark blue is the edges of the designed bridge, while red and yellow and Green areas indicate how off the mill made it. we are comparing a scan of the milled bridge, to the CAD, 3 different tries at the same file. [ATTACH=full]31085[/ATTACH][ATTACH=full]31086[/ATTACH][ATTACH=full]31087[/ATTACH] now, after modifying only the CAM parameters i was able to make that same bridge to this tolderance: [ATTACH=full]31088[/ATTACH] this bridge is now perfectly milled to my design. thats how i know how off it is even before the ceramists judge design and grind the heck out of it for funsies anyway.
