To clarify for other searches on this topic - there is no point for a student license to have access to the NC module because students typically don't have direct access to NC equipment. To drive the equipment requires post processing software to convert the tool paths into particular instructions and tool descriptions so the paths can be generated and so that reasonable paths can be programmed to begin with. When a University has NC equipment available to students they will also have set up workstations with the NC programming modules and the post processors and models of all the tools that are available to use in the NC equipment.
I think the student version can export formats that other CNC software can use, so there are alternatives in order to make parts if the school doesn't have the PTC machining module. I would expect most schools have several CAD programs in their training and would want to support just one CNC process rather than multiple different CAD programs with unique needs and interfaces.
Of course the integrated module is valuable in a commercial environment where it saves time and retains consistency in updating CNC outputs when the design changes; that's the distinguishing factor that is lost when using an export.
