I am trying to make a model in which materials arrive from source to CNC in a batch of 20 and after processing goes for shearing operation in a batch of 10, also checking which shearing machine is free to accept material. After shearing the parts are divided into various small parts (how to divide 1 entity into multiple entities?) and are moved to the bending machine depending upon specific parts are bent on specific machines. I have 1CNC, 2 Shear Machines, and 3 Bending machines. How should I simulate? I have attached my model.
