The shaft is a machine element that transmits torque and rotational motion or power. It has different shapes, depending on the stresses and changes of the cross-section in order to enable the fastening of parts that transfer torque. Therefore, main stresses that a shaft endures are torsion, and possibly bending. The slots on a shaft need to be designed correctly, because they are stress risers, in order to diminish stress concentration as a side effect of torque. The ideal shape of the shaft is be a cubic parabola, so the actual shaft needs to be designed in a way that the dimensions are larger than that of the ideal shaft. The method of material production is the method that is the most economical, error-free production in accordance with all parameters and construction of the shaft itself. Prior to machining, it is necessary to select a material with appropriate properties so that wear and tear does not occur during loading of the shaft. Given the sequence of technological processing, the workpiece is subjected to turning, then the grooves are milled, and then ground to the finished dimensions, to get the finished product of as high a quality as possible. After the shaft itself is made, it is obligatory to carry out a control in order for the product to go into further exploatation.
