Studies on Machining Parameters of Hot Machining Process using Aisi4140 Material
1.
International Research Journal
of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 04 Issue: 07 | July -2017 www.irjet.net p-ISSN: 2395-0072 © 2017, IRJET | Impact Factor value: 5.181 | ISO 9001:2008 Certified Journal | Page 3210 STUDIES ON MACHINING PARAMETERS OF HOT MACHINING PROCESS USING AISI4140 MATERIAL Jagjit Singh M. Tech. Mechanical Engineering, LR Institute of Engineering & Technology Solan, H.P, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - The experiment is conducted on conventional lathe. The temperature is controlled by a infra -rate thermometer and flame heating system. The statistical analysis is done by Taguchi method. Taguchidesignsprovidea powerful and efficient method for designing products that operate consistently andoptimallyoveravarietyofconditions. The primary goal is to find factor settings that minimize response variation, while adjusting the process on target. A process designed with this goal will produce more consistent output. A product designed with this goal will deliver more consistent performance regardless of the environment in which it is used. Taguchi method advocates the use of orthogonal array designs to assign the factors chosen for the experiment. The L9 orthogonal array of a Taguchiexperiment is selected for four parameters (speed, feed rate, depth of cut and temperature) with three levels (low, medium, and high) in optimizing the hot machining turning parameters on lathe. Key Words: Surface roughness, MRR (Material removal rate), Orthogonal array, Analysis of variance (ANOVA), Grey- Taguchi Technique. 1 INTRODUCTION The basic of hot machining operation is to first soften the work piece is by preheating and thereby shear strength gets reduced in the vicinity of the shear zone. The use of hot machining has become very useful in the machining of high strength temperature-resistant (HSTR) alloys. Hot machining has two functions to perform, one, to machine some HSTR alloys which are un Machninable in the conventional machining method. Second,toimprovetool life this eventually improves the production rate. There are various techniques of hot machining which are subjected to requirements. The penetration of heat should be such that the shear zone is appreciably affected. Input rate of heat must be commendably high,soastotemperaturesufficiently and quickly. Thermal damage done to work piece through distortion should be minimum. The installation and operation cost should be minimum. The operators in the operation should take safety measures into account. Temperature control should be quickly obtained. The obtained results indicate that the feed rate was found to be the dominant factor among controllable factors on the surface roughness, followed by depth of cut and tool’s nose radius. However ,the cutting speed showed an insignificant effect. Furthermore, the interaction of feed rate/depthofcut was found to be significant on the surface finish due to surface hardening of steel. 1.1 DIFFERENT METHODS OF HEATING Different heating methods use for heating work piece in hot machining are 1.1.1 Furnace heating Work piece is machined immediately after being heated in the furnace to required temperature. 1.1.2 Resistance heating The entire work piece is heated by passing current either through the work piece itself or through resistance heaters embedded in the fixtures. 1.2.3 Flame heating In this method, work piece material immediately ahead of the cutting tool is heated by welding torch moving with the tool. Multi-flame heads can be used for large heat inputs. 1.2.4 Arc heating: In this method, the work piece material immediately ahead of the cutting tool is heated by an electricarcdrawnbetween the work piece and the electrode moving with the tool. To prevent wandering a magnetic field can beimposedtodirect the arc. 1.2.5 Plasma arc heating: In this method, the work piece is heated using plasma arc just above the tool tip. In this method very high heat is produced. Heating can be limited to a very small surface area. 1.2 CUTTING TOOLS The most common tool materials that are used include the following: 1. High-speed steel (HSS) 2. Carbide

Insert: - Kennametal insert with Grade: KC5525 ISO catalogue number:- CNMG120408RP ANSI catalogue number: - CNMG432RP 1.3 CUTTING PARAMETERS In turning, the speed and motion of the cutting tool is specified through several parameters. Theseparametersare selected for each operation based upon the work piece material, tool material, tool size, and more. Speed Always refers to the spindle and the work piece. When it is stated in revolutions per minute (rpm) it tells their rotating speed. But the important feature for a particular turning operation is the surface speed, the speed at which the work piece material is moving past the cutting tool. It issimplythe product of the rotating speed times the circumference of the work piece before the cut is started. It is expressed in meter per minute (m/min), and it refers only to the work piece. Every different diameter on a work piece will have a different cutting speed, even though the rotating speed remains the same. [1.1] Where, v is the cutting speed in turning, D is the initial diameter of the work piece in mm and N is the spindle speed in RPM. Feed Always refers to the cutting tool, and it is the rate at which the tool advances along its cutting path. On most power-fed lathes, the feed rate is directly related to the spindle speed and is expressed in mm (of tool advance) per revolution (of the spindle), or mm/rev. Fm= f. N mm/Min [1.2] Where, Fm is the feed in mm per minute, f is the feed in mm/rev and N is the spindle speed in RPM. Depth of cut Is practically self explanatory. It is the thickness of the layer being removed (in a single pass) from the work piece or the distance from the uncut surface of the work to the cut surface, expressed in mm. It is important to note, though, that the diameter of the work piece is reduced by two times the depth of cut because this layer is being removed from both sides of the work. [1.3] Where, D and d represent initial and final diameter (in mm) of the job respectively. 1.4 ABOUT ANALYSIS SOFTWARE MINITAB 15 Minitab software is a statistics package used for analysis of experimental data. It was developed at the Pennsylvania State University by researchers Barbara F. Ryan, Thomas A. Ryan, Jr., and Brian L. Joiner in 1972. The goal of robust experimentation is to find an optimal combinationofcontrol factor settings that achieve robustness against (insensitivity to) noise factors. MINITAB 15 calculatesresponsetablesand generates main effects and interaction plots for Signal-to- noise ratios (S/N ratios) vs. the control factors. It provides standard orthogonal array for Taguchi methodology for experiment design. It also performs regression analysis to establish relation between two or more variables. It also helps in generating various types of tables and graphs. 2. EXPERIMENTAL SETUP 2.1 Work piece material: For performing hot machining, the selected material should be hard enough that at elevated temperature it should maintain the strength. Considering this, AISI 4140 as a work piece material is selected. The material is in the form of round bar and having mm diameter and mm length The material is heat treated by tempering at and oil quenched and having hardness of 50 HRc (Rockwell hardness).TheChemical,Physical andMechanical properties of material are shown below.

The main purpose of Taguchi method is reducing thevariation in a process through robust design of experiments. It was developed by Dr. Genichi Taguchi of Japan. He developed a method for designing experiments to investigate how different parameters affect the mean and variance of a process performancecharacteristicthatdefineshowwell the process is functioning. The experimental designproposedby Taguchi involves using orthogonal arrays to organize the parameters affecting the processandthelevelsatwhichthey should be varied; it allows for the collection of the necessary data to determine which factors most affect product quality with a minimum amount of experimentation, thus saving time and resources. Analysis of variance on the collected data from the Taguchi design of experiments can be used to select new parameter values to optimize the performance characteristic. 2.2.1 Process steps of Taguchi method 1. Define the process objective 2. Identify test conditions 3. Identify the control factors and their alternative levels 4. Create orthogonal arrays for the parameter design 5. Conduct the experiments indicated inthecompletedarray to collect data on the effect on the performance measure. 6. Complete data analysis to determine the effect of the different parameters on the performance measure. 7. Predict the performance at these levels 8. Confirmation experiments. 2.1.2 Signal -to- Noise (S/N) ratio The objective of problem statement is to obtain maximum value or minimum value of desired response. Taguchi method chooses to calculate the signal-to-noise ratio for finding effective parameter for desire response value. To calculate the S/N ratio, experiments are conducted in a systematic manner Taguchi’s idea is to recognize controllable and noise factors and to treat them separately as a design parameter matrix and a noise factor matrix, respectively. Experiments are organized according to orthogonal arrays (OAs). Noise factors are changed in a balanced fashion during experiments. The characteristics of S/N ratio can be divided into three categories smaller is better, Higher is better and nominal is best when the characteristic is continuous. These characteristics are selected as per objective of problem. They are calculated by following equation. (a) Nominal is the best characteristic (2.1) (b) Smaller is better (2.2) (c) Larger the better characteristic (2.3)

The effect of many different parameters on the performance characteristic in a condensed set of experiments can be examined by using the orthogonal array. Once the parameters affecting a process that can be controlled have been determined, the levels at which these parameters should be varied must be determined. Determining what levels of a variable to test requires an in-depth understanding of the process, including the minimum, maximum, and current value of the parameter. If the difference between the minimum and maximum value of a parameter is large, the Values being tested can be further apart or more values can be tested. If the range of a parameter is small, then fewer values can be tested or the values tested can be closer together. A matrix has a number of columns equal to the number of factors (parameters) to be considered, each column representing a specific factor.Withineachcolumnwespecify the levels (parameter setting) at which the factors are kept for experiments. The number of rows in a matrix represents the number of experiments that are to be performed. As the name suggests, the columns or orthogonal array are mutually orthogonal. Here, orthogonal is interpreted in the combinatory sense that is for any pair of columns, all combinations of factor levels appear equal number of times. An orthogonal array design gives more reliable estimates of factor effects with fewer experiments that are needed in traditional methods. Taguchi has tabulated 18 basis orthogonal arrays. An arrays name indicates the number of rows and columns it has and also the number of levels in each columns. For example L12 (211) has 12 rows and 11 columns each at 2 levels. The array can be directly used in many cases or modified to suit a specific problem. The number ofrowsofanorthogonal array represents the number of experiments. For an array to be a viable choice, the number of rows must be at least equal to the degrees of freedom required for the case study. The number of columns of an array represents the maximum number of factors that can be studied using that array. Usually, it is expensive to conduct experiments of the case study. The selectionorthogonal arraysfornumberofprocess parameter with respect to levels of variation of parameter are listed in the table given below table no. 3.1 Analysis of variance techniques provides a mathematical basis for organizing and interpreting the experimental results. For each performance requirement,signal-to-noise(S/N)ratiois used. The cutting parameter range is suggested by the cutting tool manufacturers. Basedonthat,inthis experiment each parameter is varied by three different levels. 2.3 SELECTION OF PROCESS VARIABLE In today’s market, productivity,surfacefinishandlongertool life are most important factors for manufacturing industry. From past literature survey it is found that several factors influence the surface roughness, material removal rate and tool wear in a turning operation. The theoretical surface roughness is generally dependent on many parameterssuch as the tool material, work material, tool geometry (tool nose radius, flank, tool runoff) machine-tool rigidity and various cutting conditions including feed rate, depth of cut and cutting speed. However, factors such as tool wear,chiploads and chip formations, or material properties of both tool and work piece are uncontrollable during actual machining. The presence of chatter or vibration of the machine tool, defects in the surface of work material, wear in the tool or irregularities of chip formation contribute to the surface damage in practice during actual machining operations. In study of effect of parameter in investigation it is notpossible consider all parameter at same time. So in this work cutting speed, Feed, depth of cut and temperatureistakenasturning process variable parameter. The cutting parameter range is suggested by the cutting tool manufacturers. Based on that, in this experiment each parameter is varied by three different levels.

FUTURE SCOPE The present work concentrated on optimization of turning process parameter in Hot Machining. The variables to be altered are cutting speed, feed, depth of cutandtemperature of work piece. The parameters to optimize are taken as surface roughness, material removal rate and toolwear.The experiment is conducted on conventional lathe. Flame heating technique is used to preheat the work piece. 1.The same experiment can performed by changing parameter i.e. by taking parameters like tool geometry, tool run off, work piece material etc. or by taking different level of process parameter. Here also higher temperature level can be selected, to observe the clear effectoftemperature on machining. 2. The tool wear criteria can be extended and tool life can also be found out. Also equation of tool life can be developed in terms of process parameters. REFERENCES [1] N.
