A Piezoelectric Servo Feed Drive for Electro Discharge Machining System Industrial Applications Using Linear Ultrasonic Motor

Abstract: A new servo drive for electro discharge machining industrial applications is presented in this paper. The development processes of the servo feed drive have passed through three main stages. The first stage focused on design and development of a linear piezoelectric ultrasonic motor. The second one concentrated on development of an electronic driver and its embedded software. The integration, testing, and validation in electro discharge machining system, was the last stage of the development iifecycle. The lin… Show more

“…It has been considered to be an outstanding machining process to produce smaller complex structures, which have wider scope of applications in aerospace industries. Machining performance of cryogenically treated tool electrodes and machining of sintered diamond have also been observed by researchers [19,20]. For micro-EDM, the most important applications are small precision cutting punches and dies, precision moulds, components for medical engineering, sensors and optics, watch making (gears and holes) or the production of small multi-component electrodes.…”

“…They have compact size, high force density, simple mechanical structure, slow speed without additional gear or spindle, high torque, nonmagnetic operation, freedom for constructional design, very low inertia, fast dynamic time responses, direct drive, fine position resolution, miniaturization and noiseless operation. These criteria gave them the potential to be used in a number of industrial applications [9][10][11][12][13][14][15][16]. Demanding and careful examination for these applications reveals that there are apparent teething issues.…”

“…Several parameters were defined as design parameters, as described in Equation (8), to investigate their contributions to the frequency variations of Mode A and Mode B, which are called sensitivities to the modal frequencies. The sensitivities of the design parameters were calculated in ANSYS and shown in Figure 5, where the x axis represents the corresponding variance ratio to their original values and the y axis represents the corresponding resonant frequencies of Mode A and Mode B.…”

“…Recently, bonded-type motors, which are small in size, have attracted many researchers' interests, but their extremely low thrust is a serious drawback. In particular, some kinds of bonded-type motors' thrusts are below 1 N [5][6][7][8], while a few of the bonded-type motors' thrusts have been improved to reach a value of less than 10 N [9][10][11][12]. Moreover, the excitation voltage, applied on the ceramics, has a limit due to the insulation and weakness of the bond.…”
