A new dynamical modeling of Active Magnetic Bearing Spindle (AMBS) to identify machining stability of High Speed Milling (HSM) is presented. This original modeling includes all the minimum required parameters for stability analysis of AMBS machining. The stability diagram generated with this new model is compared to classical stability lobes theory. Thus, behavior’s specificities are highlighte...
متن کاملActive chatter control for high-speed milling using μ-synthesis
In todays manufacturing industry, high-speed milling plays an important role. The main benefits of high-speed milling over conventional milling are the high material removal rates with relatively low cutting forces. The efficiency of high-speed milling is limited by the occurrence of regenerative chatter. Chatter is an undesired instability phenomenon, causing excessive tool vibrations, reduced...
متن کاملμ Control of a High Speed Spindle Thrust Magnetic Bearing
Experimental results demonstrate that μ synthesis provides an excellent tool for increasing the dynamic stiffness of thrust magnetic thrust bearings. Accurate system modeling and appropriate uncertainty descriptions are critical to obtaining such results and are described in detail. Both complex μ and mixed μ synthesis were used to design controllers. The performance of the μ controllers is com...
متن کاملChatter Suppression in a High Speed Magnetic Spindle by Adding Damping
Magnetic bearings are used in several applications, but they didn’t succeed in the machine tool industry, due basically to their low damping, with its associated low chatter free cutting capacity. This work shows the development of a high speed milling spindle supported on magnetic bearings with high chatter resistance. That is achieved by using control strategies which add damping to the beari...
متن کاملA miniature milling spindle with Active Magnetic Bearings
This paper describes the design and realization of a miniature milling spindle with Active Magnetic Bearings (AMBs). Permanent magnet biased, reluctance type actuators position the rotor in five Degrees of Freedom (DOF), leaving the rotation unconstrained. A rotordynamic model was developed to expedite the controller design, and enabled modeling of the spindle’s performance under the influence ...
