Impact of varying the nozzle stand off distance on cutting temperature in t...eSAT Journals
Abstract Tool wear is a natural phenomenon in all metal cutting operations due to high friction at tool work interface, which affect the tool life, product quality and accuracy of work. For minimizing the friction at tool work interface the cutting fluids or lubricants are used for cooling and lubrication, hence improvement in machining efficiency. But if the quantity and quality of lubricants are unattended or underestimated then it creates problems like soil, water, environmental pollution and also makes the machining process uneconomical. The different cooling and lubrication techniques have been developed today. So it is necessity of present day scenario of machining to work with technology which would not degrade the environment, face the competition and have better quality of products. Different research shows that conventional Flood lubrication is limited by health hazards, misting and sometime uneconomical as compared to other techniques, due to its high discharge rate of fluid. These problems have been overcome by using dry machining. Studies shows that dry machining also becomes non efficient and uneconomical during cutting of harder materials at higher cutting speed, feed and depth of cut, although it is environmental friendly and economical at particular machining level. So to minimize all these Problems of health hazards, non-economy, intense tool wear in case of flood cooling and dry machining, the minimum quantity lubrication (MQL) has been applied in this present research. The effect of varying the nozzle stand-off distance and lubricant pressure have been considered in this study, to find out the best results in terms of cutting temperature. The experimentation has been conducted during turning of EN- 31 Alloy Steel with minimum quantity lubrication at flow rate of 150 ml/hr having vegetable based oil. The temperature has been measured by K- type thermocouple .The vegetable oil has been selected due to its environmental friendly behavior and does not produce health hazards, like mineral oil during flood lubrication.

Through Lean Manufacturing Techniques Improvement InProduction of Cement PlantIJERA Editor
The production of cement is a process industry which is distinct from manufacturing and the main objective here
is to apply lean manufacturing technique to the eradicate waste to the processes and parameters which are
common between process and discrete manufacturing. Lean signifies a major advance over traditional mass
production methods. Value stream mapping is used first to identify different waste present in the current state.
This paper will describe work undertaken investigating the application of lean thinking to a continuous
production environment, in this instance exemplified by the cement industry. Implementation of lean helps
many organizations to improve their productivity and efficiency Cement plays a vital role in economic
development of any country. Having more than a hundred and fifty years history, it has been used extensively in
construction of anything, from a small building to a mammoth multi-purpose project. The need for improving
the efficiency of the cement production line is widely acknowledged in order to reduce the downtime rates, and
satisfy high levels of market demand where the demand for cement is mostly second substance behind water.
This paper articulates a methodology for data collection, knowledge extraction, model creation and
experimentation that combines the use of process mapping, computational simulation. A detailed description of
each step of the process is given and is illustrated by results from a case study undertaken during the research.
This paper describes work undertaken to implement lean practices in the continuous process sector as
represented by cement production. One of the major barriers to lean implementation is providing evidence of its
potential benefit to end-users. This work aims to overcome this obstacle by producing a tool which can be used
to easily visualize the benefits of adopting lean practices without requiring disruption to the production
environment.
COMPARISON OF MAIN EFFECT OF VEGETABLE OIL AND AL2O3 NANOFLUIDS USED WITH MQL...IAEME Publication
The growing demands for high productivity of machining need use of high cutting velocity and feed rate. Such machining inherently produces high cutting temperature, which not only reduces tool life but also impairs the product quality. Application of cutting fluids changes the performance of machining operations because of their lubrication, cooling, and chip flushing functions. But the conventional cutting fluids are not that effective in such high production machining, particularly in continuous cutting of materials likes steels. So Nanofluids have novel properties that make them potentially useful in heat transfer medium in cutting zone and Minimum quantity lubrication (MQL) presents itself as a viable alternative for turning with respect to tool wear, heat dissipation, and machined surface quality.

Abstract This paper is based on a case study in an air compressor manufacturing facility. This case study was conducted at the pressure vessel division. The pressure vessel division manufactures air receivers and air-oil separators for storing the compressed air. The facility neither had a proper model of inventory nor a replenishment policy with respect to the consumables inventory. Also there was no proper system in place to track the on-hand inventory. All the consumables were treated alike and there was not any discrimination between them. A proper model of inventory has been suggested after classifying the consumables suitably. Also a simple method to track the inventory has been proposed using an excel spreadsheet.

Optimizing the manufacturing of the nose cone of a race careSAT Journals
can be employed right from the mold making process to the actual
manufacturing of a composite part. It focuses on developing a cost-effective, time-saving and reusable mold that can withstand
relatively high pressures and temperatures and serve as an alternative to the current industry norms. The challenge lies in
effectively eliminating the pattern making stage without compromising on the surface finish of the mold.
Considering the high velocities that race cars travel with, nose cone geometry plays a critical role in dictating the aerodynamic
design that provides minimum drag and ensures optimum performance of the car. The first step in achieving this goliath of a step
has its foundation in making a coherent assembly of the nose cone while maintaining its structural integrity and strength. Based
on the experimental data, the lamination strategy was worked out to adjudicate the carbon fiber prepreg layers on the nose cone
mold.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

FAMILY MOULD DESIGN FOR QUALITY LEVERS
Ebinezar1, Bheemrao Kamble2 1Asst.professor, BKIT Bhalki, Karnataka, India 2Asst.professor, BKIT Bhalki, Karnataka, India Abstract Moulding is a process in which by pouring a molten metal into a mould cavity which is created by keeping the required shape of pattern on the molding sand and allowing the molten metal to solidify by cooling slowly. But in this process we can able to get only one shape of casting, it means shape of the final casting is limited. If we want more number of same design but not identical parts then it is not possible from a single mould, this drawback can be overcome by family moulding. This paper tells how can be able to get more number of same design but not identical parts. In another words we can say that two different parts can be produced from a single mould. This mould is called family mould. Family mould design consists of a complete mould with a few or many different cavity inserts that runs as a multiple part. Hence Family mould design for plastics levers is made here by using injection moulding machine for injection of molten plastic into mould cavity and UGNX5 software for injection mould design for plastic levers. Keywords: Injection Moulding, Pattern, Solidification, Casting, Molten
----------------------------------------------------------------------***--------------------------------------------------------------------- I. INTRODUCTION
In the injection moulding process the injected polymer flows through the sprue, runners and gate to the cavity (or cavities). The polymer flow in mould channels is unsteady and non isothermal and depends on many factors, like the properties of polymer used, injection mould design (especially cavity shape and runners configuration), injection moulding machine and processing conditions. [1]The polymer and the machine are usually the factors determined by moulded parts’ manufacturers and consumers. The melt flow in mould runners can be controlled by the design and manufacturing technology of the mould as well as by the processing conditions in order to obtain the moulded parts with expected morphology, properties, shape, dimensions and surface. [2]The cavity in the injection mould should be filled totally during the injection phase and the way of filling should be The selection of most appropriate design and technological solutions to produce certain mould should capture technical performance, economical issues as well as environmental impacts occurred during the mould life cycle. The selection of alternative mould design solutions in the early design stage It includes the use of Life Cycle Assessment methodology, Life Cycle Cost methodology and is supported by numerical simulations. [3]Assuring the proper mould temperature for a specified polymer is a very important issue as well as keeping the temperature constant and equal across the cavity surface. Differences in mould temperature can lead to the problems with manufactured parts like warpage. [4]Injection molding has been a challenging process for many manufacturers and researchers to produce products meeting requirements at the lowest cost. Its complexity and the enormous amount of process parameter manipulation during real time production create a very intense effort to maintain the process under control. What is more, complexity and parameter manipulation may cause serious quality problems and high manufacturing costs [5]. One of the main goals in injection molding is the improvement of quality of molded parts besides the reduction of cycle time, and lower production cost.
For design an [6-7] injection mould for plastic levers of HVAC the mould has to be designed to the ease of manufacturability, assembly and positive ejection of the component within the minimum possible time. HVAC is an abbreviation for heating, ventilation, and air conditioning system-the technology of indoor or automotive environment. In a vehicle heat from the engine raises temperature inside the vehicle. [8-10]Ventilating is the process of replacing air in vehicle space to control temperature or remove moisture, carbon dioxide and to replenish oxygen. Ventilation includes both the exchange of air to the outside as well as circulation of air with in the vehicle. Air conditioning means removal of heat from the vehicle using a refrigerant. Plastics are the high molecular weight polymers. Now a days to get formability, consolidation of the parts and providing a low cost to performance ratio it is necessary to make plastic castings. 1.1 Hvac

oxygen. Ventilation includes both the exchange of air to the outside as well as circulation of air with in the vehicle. Air conditioning: It means removal of heat from the vehicle using a refrigerant. 1.2 Family Mold Design Family mold is usually built to save money on multiple part types. Family mold consists of a complete mold with a few or many different cavity inserts that runs as a multiple part each cycle Family molds are often utilized when two or more part designs are similar but not identical, or if mold cost is a driving factor. Two different parts can be produced from a single mold. This can save on time and expenses by sharing common mold components such as the mold base, However, family molds are typically better suited for lower volume applications, and automation may be necessary to separate pieces during or after production. They also have the potential for greater downtime as repairs and modifications to a single part affect all the components within the mold. Some of the benefits of a family mold are lost if the parts in the mold are run in different resins. Still, with today's cost conscious buyers desire for versatility family molds is becoming an increasingly popular design option. A family mold is nothing but a multi-cavity injection mold in which each cavity forms a component part of the finished product. You can create an individual core and cavity, and individual inserts, for each plastic part. Below fig1 shows a typical family mold. Fig1. Typical family mold 1.3 Shrinkage and Warpage All materials when heated expand and on cooling contract. The method of injection moulding also is subjected to expansion of plastic during injection phase and its contraction during cooling for solidification, Hence the volume change from mould dimension to the Part dimension causing shrinkage of plastic. shrinkage of plastic depends on material and its processing.
Various factors that affect shrinkage are
1. Basic plastic material
2. Filler used and percentage
3. Part wall thickness
4. Melt temperature
5. Mould temperature
6. Injection time

Selection of machine is mainly based on three factors.
Based on clamping tonnage required
Based on shot capacity
Based on plasticizing capacity
Weight of components is 30 gms from cad model.
Based on clamping tonnage required
Clamping force Fc = Pc x {(Ap x no. of cavities) + AR}
Where,
Pc = Cavity pressure in Kg/sq.cm.
Ap = Projected area in sq.cm.
AR = Runner area in sq.cm.
PI = Injection pressure in Kg/sq.cm.
Pc = (1/2) PI for easy flow materials or (1/3) PI for
viscous materials.
Therefore, Pc = 1/3 x1000
= 333.33 kg/cm2
Ap = 62.0 cm2
Ar = 14.30 cm2
Clamping Force = 333.33 x 76.30

1. Fill time
Injection of material into the impression is equal to fill time.
Fill time = 3.26 sec (from mold flow)
2. Solidifying time
Solidifying time is proportional to square of the wall
thickness.
Ts = ρ x a x t2
8 x λ x (T mat. – T mold)
Where, ρ = Density of plastic in gm/cca = Total heat of plastic
cal/gm
t = wall thickness in cm
λ = Thermal conductivity of plastic cal/cm sec °C
Ts = 10 sec
Solidifying time = 10 sec
3. Mould opening and closing time
Approximately 10 sec.
4. Mould ejection time= 10 Sec (approx.)
5. Packing time=2Sec (from mold flow)
Cycle time = 3 + 10 + 10 + 10+2 = 35sec ------------

4. CONCLUSIONS
Family moulding is one of the most common methods used to
process plastics. We have to consider various factors to
produce a defect free and economical plastic component
during the design stage itself. Flexibility of shape of the final
casting in a single mould is achieved. Less effort of workers
and time saving can be done hence in shorter time with less
efforts of workers high efficiency involved quality casting can
be produced since family moulding process is very fast. Hence
production rate is more. When production rate is more then it
shows minimised defect castings are manufacturing hence
economical.
