With the introduction of CNC technology for these machines, this direct feedback of the spinning process was lost. The wooden bar, which was guided by the presser with his hands, is replaced here by a spinning roller mounted on a motor-driven axle. The operator controls the movement of the spinning roller via a control panel. In order to be able to "teach" the spinning process for a workpiece optimally into the CNC machine, the spinner now only has a view of the workpiece and the perception of the vibration of the machine via hearing or through direct contact with the machine for process control.

This type of feedback on the process is by far not as effective as the feedback to the hand, which also carries out the spinning process.In order to improve this feedback, we are planning to make the spinning force and the vibration acting on the spinning roller perceptible to the operator directly on the control panel of the CNC spinning machine by means of force feedback.
This will be realised by measuring the force acting on the spinning roller and then applying the force on the control unit (e.g. joystick or rotary knob) in the opposite direction to that specified by the operator. This creates a retroactive force on the pusher's hand, similar to how he would feel the force when guiding the wooden stick.
