Computer aided generative design with tool size control to facilitate 2.5-axis subtractive manufacturing processes

This invention describes a computer method for designing physical objects that will be made using a milling machine. It takes a digital model of an object, divides it into layers and small sections, and then automatically adjusts the milling depth for each section. The method specifically checks sections in the layer above the current one, and if the angle between them is too sharp, it moves the milling depth to ensure the shape can be accurately cut, taking into account the smallest milling tool available.
