“…e working principle of the ER damper is similar to that of the MR damper. Kishore et al [10] developed an electro-magnetorheological damper that can be used to control the process dynamics of the cutting tool and reduced cutting force by 12.9%. Tarng et al [11] used a piezoelectric inertia actuator which is mounted on the cutting tool to suppress chatter, and it was shown that chatter can be effectively suppressed.…”

Tangential dynamic behaviors of the machine hydrostatic slide with a magnetorheological (MR) fluid damper are studied, and the effect of the MR damper to control the vibration of the hydrostatic slide is discussed. The dynamic model of the hydrostatic slide with the MR damper is established, and the tangential vibration equation of linear and nonlinear is derived. The multidimensional incremental harmonic balance method (MIHBM) with discrete Fourier transform (DFT) is derived by which the nonlinear response and stability of the system are studied. The resonance response of the Duffing equation under the combined action of harmonic excitation and constant excitation is obtained. In order to investigate the vibration response of the hydrostatic slide with the MR damper in detail, the bifurcation diagram, phase diagram, and Poincaré map are given. Finally, the dynamic response of the machine hydrostatic slide with the MR damper is discussed, and it is verified that the MR damper can suppress the tangential vibration of the hydrostatic slide effectively and the constant controller can control the chaotic behavior of the system well.

In various machining operations, the tool condition monitoring (TCM) is highly necessary to avoid uncertain downtime in production. TCM provides continuously the condition of cutting tool by noticing various parameters such as temperature, acoustic emission and vibration. One of the best ways to monitor the condition of cutting tools for unmanned machining is by observing tool vibration signature. In the present work, vibration signals are acquired from the cutting tool. One healthy state and three faulty conditions of tools are considered for the study. The faulty tools considered in the current study are worn flank, broken tool and extended overhang. The vibration signals of these faulty tool conditions are used to train the machine learning algorithm. Statistical features are extracted from the vibration signal to feed as input to the J48 decision tree. The classifier algorithm used in the current study is rotation forest algorithm. The algorithm uses only significant features which are selected from a decision tree. The algorithm is validated with test dataset to recognize the faulty or healthy state of the tool. It was found that the algorithm could classify the tool condition with 95.00% classification accuracy.

“…The rate of settling of magnetic particles will be further accelerated as copper winding used for creating magnetic field will be heated on the application of current. It was stated that magnetic field produced is in direct accord with the current supplied to the coil [21], increasing the current will produce a higher magnetic field but will also increase the rate of settling of particles. Settling of magnetic particles also depends on the size and shape apart from that agglomeration is another major factor.…”

Vibration has been a major constraint in the machining industries as it has catastrophic effects on the machining parameter. Though there have been several attempts made by the researchers each had their own limitations and constraints. In metal cutting, Magnetorheological fluid (MRF) has proved to be effective in vibration suppression when employed as a semi-active damper. MRF is a smart non-Newtonian fluid which has the capacity to alter its viscosity instantaneously on the application of magnetic field. Along with this property and its robust nature they have used in a wide variety of places as a damper. One major limitation is its settling of magnetic particles which are suspended in a non-magnetic fluid. The settling rate will be further aggravated when the current supplied to coil is increased. Increased current will increase the heat produced in the coil which in turn will heat the non-magnetic fluid wherein its viscosity gets reduced. This problem of settling of iron particles can be prevented by adding stabilizers, similarly the size of particles also has an immediate effect on settling. In the current investigation Titanium and Activated carbon was added as stabilizers to magnetorheological fluid and then the viscosity change brought about in the fluid was studied. Further to support and add clarity to the work variable cutting speed and feed test was also performed. From the experimental results it was evident that stabilizers (activated carbon by 0.1% of weight) in MRF has increased the viscosity and thereby aided in an effective turning process of hardened SS410 steel.
