Field notes
Studio is described as modeling the controller, drives, spindle, workpiece, and cut rather than simply drawing a toolpath. The page lists a 0.01 mm height-map workpiece, 17 materials for cutting-force calculations, and tests based on ISO 230-2 positioning and ISO 230-4 circle procedures. Twinwright reports that its example programs run to completion, with 14 compared cell by cell against CAD.
