International Research Journal
of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 06 Issue: 12 | Dec 2019 www.irjet.net p-ISSN: 2395-0072 © 2019, IRJET | Impact Factor value: 7.34 | ISO 9001:2008 Certified Journal | Page 497 “OPTIMIZATION OF DESIGN PARAMETERS AND NOZZLE WEAR ON CNC PLASMA MACHINE BY EXPERIMENTATION” Mr. Dattu B. Ghane Lecturer, Department of Mechanical Engineering, Government Polytechnic Awasari, Maharashtra, India ----------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - Recently there is consistent research in machining and advancement in innovation. With increment in rivalry in advertise and to accomplish high exactness now a day the non-traditional machining is moved toward becoming help of any industry. A standout amongst the most imperative non-customary machining strategies is CNC plasma Machining. Its high precision, completing, capacity of machining any hard materials and to create mind bogglingshapebuildsitsrequestin showcase. In proposal work writing has been examined in setting to parametric improvement of CNC plasma Machining. With a specificend goal to achieve target and ideal outcomes, after find the optimization parameter the moved towered the optimization in size (design parameters) and minimum wear of nozzle. The fitting orthogonal cluster has been chosen according to number of components and their levels to perform least experimentation. The work bits of mile Steel materials were utilized for explore reason. While optimizing a plasma arc cutting nozzle design parameters to minimize the wear, several but selective machine process parameters and nozzle design parameters given by the various stack holders. This experimentation includes the process parameters as specifications given by manufacturer, dimensional accuracy report, roughness parameters analysis, material removal rate analysis and n addition to this, nozzle design parameters after burning the nozzle as, nozzle shell diameter, nozzle length, nozzle inner shell center pin diameter etc. Experimentation and parameters analysis comes about are given to affirm the viability of this approach. Key Words: CNC Plasma, material removal rate, nozzle were, operating parameter, surface roughness etc. 1. INTRODUCTION The topic for this thesis writing is to Analysis the Process Parameters of CNC Flame Cutting Using Design & Experiment Techniques. The focus on this project is to obtain an optimum condition (setting)toobtainminiMRRandminimumthesurface roughness (SR)[1]. A person does not need to be a physicist & chemist to understand the CNC Flame Cutting and Gouging process. There are four states in which physical matter may be found solid, liquid, gas. Changes from one physical state to another occur due to, by supplying or subtracting energy, in the form of heat. Water can be used as an example of these four states of matter. In the solid state it is ice at temperatures of 0 degrees Celsius or colder. With the additionofheat,theicemelts and changes to water, the liquid state. The addition of more heat to temperatures of 212 degrees F. (100 degrees C.) or hotter) converts this liquid to its gaseous state, steam. If you happen to be reading this by the light emitted by a fluorescent lamp you see flame in action. Flame of glowing tube contains sodium vapor or mercury. It is ionized by a high voltage across electrodes at the ends of the tube and conducts an electric current which causes the flame to radiate which in turn causes the phosphor coating on theinnersurfaceof thetubeto glow. For quick cutting of steel plate oxy-acetylene cutting process was preferred. From the last few years’ plasma cutting has pretty much taken over, for some very good reasons to perhaps most importantly.The plasma cuttingiselectricallyconductive process [14]. That means that one unit will cut steel, stainless steel, aluminum, copper, bronze, and brass etc. 1.1 Problem Statement CNC Plasma Arc flamearc cutting can be characterized in terms of two distinct speeds. At cutting speeds on the top of, theflame jet does not track metal plate. At speeds below, the liquid metal to all-time low of the plate, forming the questionable dross and the way to properly choose aflame cutting system. The CNC Plasma Arc flamecutting process employsaflametorchwithavery slender bore to produce a transferred arc to the work piece at a mean current density of within the bore of the torch[6].

PRINCIPLE OF PLASMA CUTTING Plasma cutting are forms that utilization fuel gases and oxygen to cut metals, individually. French specialists Edmond Fouché and Charles Picard turned into the first to create oxygen-acetylenecuttingin1903[1]. Pureoxygen,ratherthanair, isutilizedto expand the fire temperature to permit confined dissolving of the work piece material (e.g. steel) in a room situation. A typical propane/air fire consumes at around 2,250 K (1,980°C; 3,590 °F), a propane/oxygen fire consumes at around 2,526 K (2,253 °C; 4,087 °F) [3], and an acetylene/oxygen fire consumes at around 3,773 K (3,500 °C; 6,332 °F). Plasma is one of the most established cutting forms. Still utilized as a part of industry,inlatedecadesithasbeenlessbroadlyusedinmodernapplications as other particularly conceived advances have been received. It is still generally utilized for cutting metal plates and tubes, and in addition repairs work. It is likewise as often as possible appropriate, and supported, for manufacturing a few kinds of metal-based fine art. Also, Plasma has favorable position over electric cutting procedures in circumstances where getting to power (e.g., by means of an additional line or convenient generator would show challenges; it is more independent, and, henceforth, frequently morecompact.InPlasma cutting,a light is utilized to warm metal to its fuel temperature. A surge of oxygen is then prepared on the metal, consuming it into a metal oxide that streams out of the kerf as slag. 3. EXCPERIMENTAL SET-UP While doing this the terms like tool magazine capacity, tool life and its availability are taken into consideration. This will be useful to avoid negative results. The proposed design approachwill providean effective decisionmakingtool forthe shortterm operational decisions of FMS. 3.3 Controller The control panel is essential component or part of any CNC machine because it has various switches on it. That is used to control the various parameter of machine. By the control panel of CNC flame cutting machine we can control the nozzle movement, flame velocity, gas pressure, air gap as per our need, due to this variousswitcheswecanimproveaccuracyandalso save our time. 3.4 Sample Mild Steel material, four quantity samples, having 10 mm thickness and 200 mm x 200 mm size taken for the experiments. 4. METHODOLOGY Minimum wear of nozzle is found out by the experimentation done on CNC Plasma arc cutting machine. To start the experimentation firstly optimization of CNCPlasma arccuttingmachinedesign processparametersisdone by experimentation analysis. Different machine manufacturers and nozzle suppliers suggest differentoperatingparameterstobeused onmachine for cutting which leads more wear of nozzle. Hence by experimentation on the machine optimize process parameters and design parameters which gives best results with minimum wear of nozzle for different nozzles as: 1/16; 3/64; 1/32; 5/64. Figure No.: 3.1: Mass cutting machine Source: Kalpak Industries, Ahmednagar 2019 3.1 Bed It is heavy duty massive construction to provide stiffness to sustain large cutting dynamic force, load of other elements etc. It is made of high quality granite and it acts as foundation for all other parts of the machine. 3.2 Gas Bang A 2-phase approach is developed to solve the tool magazine arrangement and operations sequencing related problems. By utilizing the benefits of tool sharing concepts, loading of duplicate tools, it will lead to decrease the tooling and operational cost.

SIMULATIONS OF NOZZLE 7.1 Nozzle: A nozzle is a pipe or tube of varying cross sectional area, and it modify the flow of a fluid, liquid or gas or it will also directs identical. Spouts square measure regularly won't to the board the speed of stream, speed, heading, mass, shape, and additionally the weight of the stream that rises up out of them. In a very nozzle, thespeedoffluid will increaseatthe expenseof its pressure energy. A gas jet, fluid jet, or hydro jet may be a nozzle meant to eject gas or fluid in a very coherent stream into a close medium. Gas jets square measure ordinarily found in gas stoves, ovens, or barbecues. Gas jets were ordinarily used for lightweight before the event of electrical lightweight. Alternative varieties of fluid jets square measure found in carburetors, wherever swish graduated orifices square measure wont to regulate the flow of fuel into associate degree engine, and in Jacuzzis or spas. Another specialised jet is that the bedded jet. This is often a waterjetthatcontainsdevicestofreethe pressure and flow, and offers streamline flow, as its name suggests. This offers higher results for fountains. The froth jet is another variety of jet that uses foam rather than a gas or fluid. Nozzles used for feeding hot blast into a furnace or forge square measure referred toastubers.Jetnozzlesalsoareemployedin giant rooms wherever the distribution of air via ceiling diffusers isn't doable or not sensible. Diffusers that use jet nozzles square measure referred to as jet diffuser wherever it'll be organized withinthefacetwall areassoastodistributeair.Oncethe temperature distinction between the availability air and therefore the area air changes, the availability air stream is deflected upwards, to produce heat air, or down, to produce cold air. 7.2 Sample Mild Steel material, four quantity samples, having 10 mm thickness and 200 mm x 200 mm size taken for the experiments. 7.3 Machine Parameters: 7.3.1 Operating Parameters (Optimized) Used for Optimization of Nozzle Design Parameters as: Sample No. Cutting Speed (mm/min) Oxygen Pressure (bar) LPG Pressure (bar) Air Gap (mm) 4 700 0.12 0.12 1.1 Table No.: 7.3.1: Optimized operating parameters used 7.4 Nozzle Sample Details The material selected as MS for NOZZLE is EN47.

CONCLUSIONS Literature survey on method parameters of plasma arc cutting has been studied and Experimental work has been administrated. From that it is concluded that: 1) MRR and surface roughness values are affected bycutting parameterssuchasGaspressureandmaintainedarcgapasshown in Table No.: 6.2, 6.3, 9.2 and Table No.: 9.3. 2) There are different operating parameters suggested by Kalpak industry, Nozzle provider (ESAB), Mass cutting machine provider, operating parameters taken by operator and company expert as per expertise (R & D) as given in Table No: 5.1, 5.2, 5.3 and Table No.: 5.4. So among these parameters advised for right parameters selection as given in Table No.: 7.3.1. 3) From Dimensional analysis it is concluded that after cutting, sample width varies at different sections as given in Table No.: 6.1 and Table No.: 9.1. 4) Material removal rate is higher while amount of material removed is less. 5) As the Material removal rate increases the time required to cut the part is less. 6) The surface roughness is having lower value resulting surface finish of part is good that reduces the cost of after processing operations. 6) In nozzle wear analysis found that the 3/64 type nozzle is the best for all results as shown in Table No.: 10.
