A highly dynamic lens processing machine with a machine bed having at least a first tool holder and one workpiece holder with an axis of rotation and including a workpiece spindle arranged thereon. According to one aspect of the present invention, a computer system includes a preloader, a compiler, and a virtual machine. An optical unit is optically coupled to the pair of modulators, which are capable of modulating an optical beam in response to a signal provided by the signal source. The received function-access data includes first function-access data that specifies access credentials of a first user to access the particular function and second function-access data that specifies access credentials of a second user to access the particular function.
