Automated inspection technology is integrated with a cylindrical container print decorator machine to optimize the decoration process by making critical process and machine information properly and immediately available for corrective adjustments to the process. With this information, a high speed decoration machine operator will be made directly aware of the portions or subsystems of the decorator machine not functioning properly. The information directly facilitates, and can even recommend, corrective adjustments that are necessary to the decorator to better optimize printing functions. It is possible to use this information to optimize the operation of the decorator. It is possible to use this information by way of a properly configured control system, after specific augmentation capabilities are added to the decorator machine, to automatically close the loops with specific decorator printing machine parts or subsystems to dramatically improve the decorating process even while the machine is printing.

A customer sends a CAD file for the part to be manufactured to the system. The system assesses the CAD file to determine various pieces of manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be machined in two opposing orientations in a 3 axis CNC machine. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities or parts per workpiece block, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts, which may include both molded parts and total profiled machined parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer. Interactivity is also achieved, with the customer being able to modify the quotation interactively by modifying one or more of the initially selected parameters, including selecting a different budgeted amount.

Manufacturing processes profit greatly from a close collaboration between human and machine. Whereas a human behaves flexibly and adaptively but is inclined to make mistakes during repetitive work operations, machines operate quickly and exactly but are static and not very flexible. In order to enable an improved hazard protection in the context of a safe human-machine interaction, a spatial- and time-dependent variable degree of hazard is allocated to monitored spatial areas as a function of the current position and the current movement state of a machine or a machine element, as well as of the observed person. For this purpose, a multicamera system is used to acquire image data of the person in order to obtain the most detailed information possible about the position and alignment of a person, in particular also with reference to the body parts thereof, in an industrial environment. These image data are then examined with regard to the imaging of a person so that whenever a person has been detected in the image data, an articulated virtual 3D model of the human body is matched to this person hypothesis. Subsequently, this virtual body model is continuously matched to the movement behavior of the person detected in the image data. A hazard potential is determined using knowledge of the position and the movement behavior of the virtual body model in space. The hazard potential thus determined is subjected to a threshold value comparison in order to act upon the movement control of the machine or the machine part in the event of this threshold value being exceeded.
