1. A method for manufacturing a screw rotor, the method comprising:
performing a first clamping by clamping a workpiece within a grinding machine, the workpiece having already been partially processed to have a shape of a rotor with a first clamp;
performing one or more cylindrical grinding operations on the workpiece with one or more cylindrical grinding disks, wherein the one or more cylindrical grinding operations are one or more cylindrical abrasive grinding operations and wherein the one or more cylindrical grinding disks are one or more abrasive cylindrical grinding disks;
performing one or more profile grinding operations on the workpiece with one or more profile grinding disks, wherein the one or more profile grinding operations are one or more profile abrasive grinding operations and wherein the one or more profile grinding disks are one or more abrasive profile grinding disks, wherein the one or more cylindrical grinding operations and the more profile grinding operations are both performed by the grinding machine;
switching by the grinding machine between the one or more cylindrical grinding operations with the one or more cylindrical grinding disks and the one or more profile grinding operations with the one or more profile grinding disks; and
controlling both the one or more cylindrical grinding operations and the one or more profile grinding operations of the manufacturing of the rotor by a controller of the grinding machine.
