The present study deals with the machining of hybrid Al 7075/B4C/Gr composite using Abrasive Aqua Jet Machining. The effects of selected input factors, i.e., water jet pressure (WJP), stand-off distance (SOD), and traverse speed (TS) on the performance characteristics, namely taper angle (TA), surface roughness (Ra), and the material removal rate (MRR) are investigated. The experimental runs and test strategies are formulated using the Response Surface Methodology-Central Composite Design approach. Analysis of Variance (ANOVA) was used to examine the effect of input factors and their interactions with performance characteristics. MRR, Ra, and TA optimum condition and mathematical equations were also developed. Further, the multi-optimization method “Technique for Order of Preference by Similarity to Ideal Solution” is considered to find out the best combinations of input factors for optimized output factors on the hybrid composite. The ANOVA results confirm that among the input factors, WJP and SOD are the most significant factors, and the percentage distribution of input factors are found to be jet pressure (55.21%), stand-off distance (23.36%), and traverse speed (2.56%). The multi-objective optimum conditions of the input factors are WJP (A1) 210 bar, SOD (B1), and TS (C3) 30 mm/min, that produce optimal values of the considered responses, i.e., MRR up to 4.8703 mm3/min, Ra up to 3.57 μm and TA up to 0.189°. The TA has improved by 49.6% through the multi-objective optimum results when compared with single parameter optimized results. Article Highlights Hybrid Al7075/B4C/Gr composite fabricated through the rotary stir casting technique Experimental planning and designing layouts using Response Surface Methodology scheme and mathematical equations are produced with Design Expert 11.0. The best TA was obtained by RSM-TOPSIS approach, found at a lower WJP and SOD and a higher TS.

“…Cryogenic cooling also paved way for tool vibration reduction and raised the quality of machined products with very low energy usage (Yildiz and Nalbant, 2008). Cryogenic cooling was used with liquid nitrogen to suppress vibrations while machining titanium alloy Ti-6Al-4V (Hong et al, 2001) and Inconel 718 (Deshpande et al, 2018), which are very tough and produce large amplitude chatter in turning operation and similarly in milling operation (Huang et al, 2014).…”

Purpose A new cutting tool is always well-defined and sharp at the onset of the metal cutting process and gradually losses these properties as the machining process advances. Similarly, at the beginning of the machining process, amplitude of tool vibrations is considerably low and it increases gradually and peaks at the end of the service period of the cutting tool while machining. It is significant to provide a corresponding real-time varying damping to control this chatter, which directly influences accuracy and quality of productivity. This paper aims to review the literature related to the application of smart fluid to control vibration in metal cutting and also focused on the challenges involved in the implementation of active control system during machining process. Design/methodology/approach Smart dampers, which are used as semi-active and active dampers in metal cutting, were reviewed and the research studies carried out in the field of the magnetorheological (MR) damper were concentrated. In smart materials, MR fluids possess some disadvantages because of their sedimentation of iron particles, leakage and slow response time. To overcome these drawbacks, new MR materials such as MR foam, MR elastomers, MR gels and MR plastomers have been recommended and suggested. This review intents to throw light into available literature which exclusively deals with controlling chatter in metal cutting with the help of MR damping methods. Findings Using an MR damper popularly known for its semi-active damping characteristics is very adaptable and flexible in controlling chatter by providing damping to real-time amplitudes of tool vibration. In the past, many researchers have attempted to implement MR damper in metal cutting to control vibration and were successful. Various methods with the help of MR fluid are illustrated.

“…By means of the analytical model, it is noted that specific cutting energy reduces when the flow rate and pressure of the MQL process increase [7]. The usage of MQL technique with a cryogenically treated tool inserts shows improved results in terms of minimum surface roughness [8]. In addition to the above literature, it becomes customary to prepare sustainable machining setup in order to provide a multi-type of cooling medium like dry, near dry, liq.…”

In the present research a novel cooling setup that can help the turning process to be performed in various media, i.e., dry, liquid CO 2 or compressed air, cooling lubricant, and the mixture of the liquid CO 2 or compressed air mixed with the cooling lubricant. The conventional cooling oil is used to dissipate the heat and increasing life of a cutting tool. So, the surface finish of the workpiece improves leading to a better quality product. Customarily, the contaminated cutting fluid needs to be disposed of after its use that involves a good amount of money of total manufacturing cost. Primarily this work is a turning operation on Al 3055 alloy under three different cutting media namely dry, Liq. CO 2 and Liq. CO 2 assisted the minimum quantity of liquid in order to get better quality of the product.
