Nickel based materials of Nimonic C-263 and Waspaloy are used nowadays for aerospace applications owing to its superior strength properties that are maintained at a higher temperature. Tool wear and cutting temperature in the vicinity of cutting edge are two essential machinability characteristics for any cutting tool. In this regard, this study is pursued to examine the influence of factors on measuring of tool wear (Vba) and cutting temperature (Ts) during dry machining of two alloys studied experimentally based on Taguchi method and response surface methodology. Taguchi’s L16 orthogonal array is used to design the experiment and a PVD (TiAlN), CVD (TiN/Al2O3/TiCN) coated carbide inserts are used on turning of two alloys. The factor effect on output responses are studied using analysis of variance, empirical models, and responses surface 3D plots. To minimize the response and to convert into one single optimum level, responses surface desirability function approach is applied. The results show that progress of flank wear associated with Waspaloy is faster that of Nimonic C-263 due to high cutting temperature for Waspaloy that…

To survive in the present global competitive world, the manufacturing sectors have been making use of various tools to achieve the high quality products at a comparatively cheaper price. Appropriate cutting set up must be used to further better the machinability of a work piece material. A longer life of the tools and equipment’s are important factors in any industry. Since the inception of the machine tool industry, cutting tool life and tool wear remain a subject of deep interest to study its failure and improvement. The present study finds out the optimum cutting results in drilling of AM60 magnesium alloy using different cryogenically treated cutting inserts. The Utility concept coupled with Taguchi with Multi response approach (TOPSIS) was employed. According to Analysis of variance (ANOVA) results, the feed was the major dominating factor followed by the cutting speed. This work deals with optimization approaches for the determination of the optimum process parameters by cryogenically treated drill HSS tools which minimizes surface roughness, torque, tool life, entry burr and tool cost, and maximizes material removal…

Published 2019-10-11 by SAE International in United States
Inconel 625, nickel based alloy, is found in gas turbine blades, seals, rings, shafts, and turbine disks. On the other hand, the manufacturing of this alloy is challenging, mainly when machining processes are used due to excellent mechanical properties. Application of nanofluids in minimum quantity lubrication (MQL) shows gaining importance in the machining process, which is economical and eco-friendly. The principal objective of this investigational work is to study the influence of three types of nanofluids in the MQL turning of Inconel 625 nickel based alloys. The used nanofluids are multi-walled carbon nanotubes (CNT), alumina (Al2O3) and copper oxide (CUO) dispersed in vegetable oil. Taguchi-based L27 orthogonal array is used for the experimental design. The parameter optimization of design variables over response is carried out by the use of Taguchi-based derringer's desirability function. The design variables are machining parameters (speed, feed), nanofluids (Al2O3, CNT, CUO), and three different weight percentage (0.1, 0.25, and 0.5 wt. %). The results showed that minimum values of surface roughness could be achieved at 0.10 wt. % of nanoparticles, CNT…

Cutting liquids are important for cutting titanium. In spite of the fact that ventures are discovering routes that to cut titanium dry, the properties of this material reason imperative deterrents for doing this. It is sticky, has low Thermal conductivity, and highlights a low flash point. Thus, the chips don't divert the warmth, and the work will get sufficiently hot to touch off and consume. Cutting Fluids thwart the issue by greasing up the sting, flushing the chips away and cooling the work piece. To guarantee that the cutting liquid plays out these capacities well, titanium combinations lean toward cutting liquids conveyed at a high weight, generally inside the scope of 4,000 psi. to 7,000 psi. This thinks about reports the aftereffects of a Turning test led on the Ti- 6Al- 4V compound of the symmetrical exhibit with Grey relational analysis by Taguchi Method. Spotlights on the improvement of Turning process parameters utilizing the system to get least surface Roughness (Ra), Maximum MRR, Min Tool Wear and Thrust Force with Minimum Industrial pollutants like coolant.…

Composites materials are substituting constituents for traditional materials due to their remarkable properties, and the addition of nanoparticles gives a new development in the material domain. The nanoparticles influence on fabrication and machinability investigation study is essential as the composites to be used in applications like automotive and aerospace. The current study investigates the machinability characteristics of Al2219 based metal composites reinforced with nanoparticles of SiN/MoS2. Al2219- reinforcements (SiN and MoS2) composites are fabricated by the method of stir casting. Four different compositions (Al2219/SiN (2 wt% and 4 wt%), , Al2219/2 wt.% SiN/ 2 wt.% MoS2, Al2219/2 wt.% MoS2) are fabricated by varying the different weight percentages of nanoparticles reinforcements.

Published 2019-10-11 by SAE International in United States
The present work compares the tribological properties of ZnO (Zinc Oxide) nanoparticle based lubricant with ZDDP (zinc dialkyl dithiophosphate) based lubricant. The nanolubricant was prepared by mixing the nanoparticles in base oil followed by ultrasonification and ZDDP based lubricant was prepared by mixing ZDDP and stirring with base oil. Base oil used was mineral base oil. Both the lubricants were tested at three different temperatures, loads and roughness values. The test was carried out on AISI 52100 steel samples prepared by wire cutting and were grinded to three different levels of surface roughness. Friction and wear tests were performed using a reciprocating sliding tribo-tester at three different loads and temperatures. Taguchi orthogonal array was used to reduce the number of experiments. SEM, EDS and AFM analysis were carried out to study the surface wear phenomenon. The coefficient of friction was found to be low in the case of ZnO nanolubricant but wear was found to be high compared to ZDDP based lubricant.

Waterjet machining is a widely used advanced machining technique because of its versatility in removal of material for a wider range of materials. Waterjet machining is particularly advantageous in the precise cutting of advanced materials like Fiber Reinforced Polymers (FRPs) comparative to conventional machining methods. The conventional machining methods result in the release of high amount of glass fiber dust which leaves the work environment unsafe for the workers. The material dust if inhaled can lead to acute respiratory diseases. In this work an analysis was done on the cutting performance of Waterjet machining and is presented based on an experimental investigation on fabricated fiberglass reinforced laminates. It is shown that with a good combination of cutting parameters such as nozzle traverse speed, waterjet pressure, and Stand-off distance a cutting performance can be achieved. Plausible trends of kerf quality and machining time with respect to the waterjet pressure, nozzle traverse speed and nozzle stand-off distance are analysed. The surface roughness and machining time has been optimized using DOE techniques for achieving proper machining characteristics and…
