Abstract
This paper describes an approach for implementing the STEP-NC standard in additive manufacturing. Geometric information of additive manufacturing layers is used as input data to generate the STEP-NC program according to ISO 10303 AP-238. An adapter software was developed to convert the additive layer data into the AP-238 STEP-NC data. Additive STEP-NC program verification is carried out through toolpath simulation within the STEP-NC Machine software environment, including the configuration of the machine’s kinematic 3D-model and the tool shape geometry. Validation of the approach is also realized by manufacturing a test part on a real RepRap 3D printer. This method is a feasible way to use STEP-NC in additive manufacturing (3D printing) processes.
