Abstract
A computer-implemented method for the automated adjustment of the position of a cutting tool when cutting dental aligner material includes using a computer for generating digital data that define (a) a first cutting angle in a labial cutting area along a dynamic cutting curve, (b) a second cutting angle in a lingual cutting area along the dynamic cutting curve, and (c) a third cutting angle in a back molar cutting area along the dynamic cutting curve. The cutting tool is automatically moved from the labial cutting area to the back molar cutting area while gradually increasing a cutting tool angle from the first cutting angle to the third cutting angle. The cutting tool is also automatically moved from the lingual cutting area to the back molar cutting area while gradually increasing the cutting tool angle from the second cutting angle to the third cutting angle.
