Abstract
The present application relates to systems and methods for removing support structures in subtractive machining. The systems and methods include an additive component; a subtractive component; and a processor configured to: receive a contact line associated with a support structure from the additive component; receive a geometry associated with an orientation from the additive component; receive data associated with a tool from the subtractive component; generate a subtractive tool path based on the received contact line, the received data associated with the tool, and the received geometry; transmit the generated subtractive tool path to an analysis component for tool path validation; and validate the tool path by the analysis component based on output from a simulation component to determine whether the subtractive component successfully calculated removal of the support structure from the part.
