A computer model of a non-linear ultrasonic vibrating system with the possibility of autoresonant control is presented in this paper. The system controlled consists of two modules, the first of which is an electromechanical model of an ultrasonic transducer comprising a piezoelectric transducer and a step concentrator. The second module simulates an influence from the machining process. Coefficients of the electromechanical model and its validity were estimated through an identification process based on the experiments with a real ultrasonic transducer. Further, a numerical model of the autoresonant control of this system has been developed. The autoresonant control maintains the resonant regime of oscillation by means of positive feedback, which provides transformation and amplification of the control signal. The model allows the use and comparison of three control strategies depending on the different electrical and mechanical feedback control signals. The results from simulation and from real machining experiments under different control strategies are compared and discussed.

“…Both solutions require supplementary operations, and energy. Vibrations have been known to influence material process during forming [1] or even cutting [2]. Some studies have demonstrated that applying ultrasonic vibrations superimposed to the movement of die can reduce the force, similarly to the previous solutions [3], [4].…”

Abstract-This paper addresses the control of a tool developed to superimpose vibrations along several directions on a piece during forging. Piezoelectric actuators are used to provide the required forces and speeds. Due to the minute displacements of the actuators, flexible hinges are used in a special arrangement in order realize the specified movements and to ensure controllability. The experimental results confirm the approach.

“…Aside from the obvious advantages, other effects can include the hardening of the machined surface due to the continuous hammering effect of the tool [11]. Different materials have been studied under UAT to try to evaluate the optimum machining conditions as well as to increase our knowledge in that new area [12]. These materials include super alloys as well as aviation materials, both being perfect candidates for such study because of their hard machinability under conditions of the classical conventional cutting (CT) [13].…”

“…Ultrasonic Assisted Turning (UAT) can be utilized with either single-direction vibration or twodirection vibration. In single-direction vibration the system vibrates in only one direction and the transducer system is fairly straight forward, while in the case of two-direction vibration (ultrasonic elliptical vibration cutting) the system is much harder to design [14], [12], and [15]. The aim of this paper is to study experimentally the effect of changing different machining parameters on machining stainless steel (SS) and brass under conditions of both CT and UAT.…”

Analysis of the influence of cutting parameters on surface roughness and cutting forces in high speed face milling of Al/SiC MMC R Ghoreishi, Amir H Roohi and A Dehghan Ghadikolaei It is superior to conventional turning (CT) with regard to cutting forces, surface quality and machining accuracy. The aim of this study is to investigate the effect of different machining parameters on stainless steel and brass alloys, during both UAT and CT, and evaluate improvements of cutting forces, surface roughness, surface integrity, and machining accuracy. An experimental setup for UAT at Loughborough University was used to accomplish this investigation. This setup used a Picoscope data acquisition add-on with Kistler threecomponent dynamometer, Seco DNMG cutting inserts were utilized, a surface tester from Taylor Hobson was used to evaluate surface roughness, Alicona Infinite Focus microscope was used to evaluate surface roughness and surface integrity, while Metris CMM with Renishaw probe was employed to evaluate machining accuracy. Cylindrical workpieces of steel and brass alloys were turned under CT and UAT conditions; cutting forces, surface roughness, and machining accuracy produced with both techniques where compared. Significant improvements were noticed in the ultrasonically assisted machining when compared to the CT for both alloys.
