HYBRID ADDITIVE AND SUBTRACTIVE MANUFACTURING SYSTEM AND METHODS OF OPERATION

摘要

A manufacturing system and method combines additive material deposition at a coarse resolution with high speed subtractive material removal at part surfaces to maximize detail and dimensional accuracy. Additive and subtractive operations may be performed sequentially or in parallel. Model data is received and support model data for undercuts, overhangs, and constrained surfaces is generated. The model and support model data is partitioned into additive and subtractive layers. Additive toolpaths are generated for each of the additive layers and subtractive toolpaths are generated for each of the subtractive layers. The subtractive toolpaths from adjacent subtractive layers may be consolidated, and then scheduled using a spatial-temporal map to resolve dependencies on additive toolpaths. A hybrid manufacturing program including the additive and subtractive operations is output.
