## 4 Technical Solution for Method Implementation  
In the case of current toothing equipment, the gear pair located on the machine table ensures both the table translation (motion II) and plate rotation (motion III), as shown in Figure 22, so that the rolling condition for obtaining involute teeth is realized according to part's number of teeth and its module. To implement the method for increasing the efficiency of the previously presented toothing process, the need to adapt the technological equipment must be considered so that the rotational and/or translational motions of the workpiece and the machine table should be controlled in order to vary the rolling motion speed. Figure 21: Uniformization of the detached chip section during the turning of a globoid worm (\(z=20\) teeth, \(m=5\) mm) [25]. Two alternatives for driving the machine table can be approached, which are different from the current mode (equal size steps, leading to the obtaining of detached chips with time-dependent variable sections). The first alternative consists of actuating the machine table using an electric motor coupled to the connection point L between the mechanism located on the machine table and the classical actuation circuit (with which the kinematic communication will be interrupted). The advantage of this alternative lies in the fact that only one motor and its control circuit are used. Also, the tool vs. part rolling condition is preserved by means of the rigid connection between the two motions through the exchangeable gear pair. This alternative, however, has the disadvantage that it requires a more powerful electric motor, which should be able to drive the entire mechanism of the table in motion. The use of a motor, connected in this manner, ensures compliance with the rolling condition by using the wheels of the adjustment mechanisms used in the case of classical machining. The second alternative consists of the use of two electric motors that generate separate and correlated motions I, (II), and III, respectively. Although the disadvantage would be the need to use two electric motors, with two control circuits, these motors can be smaller and implicitly have a lower purchase cost. Also, these motors, since they are actuated separately, can make the necessary division motion much easier during the workpiece machining. After a trade-off, we propose, in what follows, the application of the first alternative. To substitute the classic drive of the workpiece table and plate with an electric motor, the driving system must be chosen, and the set-up must be dimensioned. The choice and dimensioning of the set-up are imposed by the technological process that is carried out. In this case, the type of electric motor and the set-up are established taking into account the following aspects:  
* To be able to make frequent starts and stops, because the number of double strokes per minute made by the cutting tool is of the order of tens. On each double stroke, the motor must start, move, or rotate the table on a prescribed distance, and brake. At a speed of 30 double strokes/minute, the motor will have to make approximately 1800 starts/hour, which greatly limits the possibility of choosing the motor type. * To consider the order of magnitude of the power required for operation, investment and exploitation expenses, yield, energy consumption, and others. Figure 22: Simplified kinematical schema for the driving chain of the part table and rotating plate on the slotting machine. Since the motor drive is intermittent, the speed is chosen so that the kinetic energy stored in the motor-machine system is minimal. When choosing the type of motor for the electrical actuation of the mechanism, theoretically, we can choose from a variety of motors (asynchronous, synchronous, three-phase, single-phase) operated by frequency converters, continuous current motors, and stepper motors.
