Application of ANN and PSO Swarm Optimization for Optimization in Advanced Manufacturing

CNC lathe is one of the best machining techniques which provides us with better accuracy and precision. Considering speed, feed and depth of cut as inputs and among all possible outputs, in the present work Material Removal Rate and Surface Roughness would be considered as the factors those affect the quality, machining time and cost of machining. Design of experiments (DOE) would be carried out in order to minimize the number of experiments. In the later stages application of Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO) would be used for the Optimization in the advanced manufacturing considering CNC lathe. The obtained output would be minimized (for surface roughness) and maximized (for MRR) using Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO). The combination of various input parameters for the same would be identified and a comparison would be drawn with the various above methods.

Multi-Objective Optimization of CNC Turning Process Parameters Considering Transient-Steady State Energy Consumption

Energy-saving and emission reduction are recognized as the primary measure to tackle the problems associated with climate change, which is one of the major challenges for humanity for the forthcoming decades. Energy modeling and process parameters optimization of machining are effective and powerful ways to realize energy saving in the manufacturing industry. In order to realize high quality and low energy consumption machining of computer numerical control (CNC) lathe, a multi-objective optimization of CNC turning process parameters considering transient-steady state energy consumption is proposed. By analyzing the energy consumption characteristics in the process of machining and introducing practical constraints, such as machine tool equipment performance and tool life, a multi-objective optimization model with turning process parameters as optimization variables and high quality and low energy consumption as optimization objectives is established. The model is solved by non-dominated sorting genetic algorithm-II (NSGA-II), and the pareto optimal solution set of the model is obtained. Finally, the machining process of shaft parts is studied by CK6153i CNC lathe. The results show that 38.3% energy consumption is saved, and the surface roughness of workpiece is reduced by 47.0%, which verifies the effectiveness of the optimization method.

EFFECT OF CUTTING PARAMETERS ON CUTTING FORCES IN TURNING OF CPM 10V STEEL

The objective of this paper is to investigate the effect of cutting parameters on cutting forces during turning of CPM 10V steel with coated cutting tool. Machining of CPM 10V steel and finding a suitable tool is very challenging due to its physical and mechanical properties, especially since the machining of this material has not been extensively researched. The experiments were carried out using an Index GU -600 CNC lathe and the cutting forces were measured in process. A three-factorial three-level experimental design was used for the experiments. Statistical method analysis of variance (ANOVA) is applied to study the effects of cutting speed, feed rate, and depth of cut on cutting forces. The results of this study show that depth of cut has the most significant effect on main force and radial force, while feed rate and cutting speed have the most significant effect on feed force. The developed model can be used in the machining industry to predict and analyze cutting parameters for optimal cutting forces.

Measurement of Outside Thread Pitch Distance Results of TONGTAI TCS 1500[M] CNC Lath Using Profile Projector

Research has been carried out on the Measurement of the Outer Thread Pitch Distance from the Tongtai Tcs 1500[M] Cnc Lathe Using a Projector Profile. The use of a screw system to unite two components, is almost always found in all industrial technology results from the form of industrial technology with a low level of accuracy (rough) to a very high level of precision (precision). Therefore the screw system has become one of the important factors in industrial progress in all types of production. The higher the level of a component made means the higher the level of accuracy of the thread system. In this study, calculations were carried out to determine the level of precision of a thread made through the machining process using a TONGTAI TCS 1500 [M] CNC lathe. The precision measurement was carried out by measuring using a dimension measuring instrument, namely Profile Projector type HST-CPJ-3000/3000Z. To find out the average value and the value of the screw deviation, a research and measurement process was carried out with several product samples or test objects (sample A, sample B, sample C) where each sample was the same size, namely M15 × 50 P 1.5. The first measurements were made on the major and minor diameters. Because this measurement is more focused on the level of precision of the thread pitch distance, the second measurement is carried out by measuring the dimensions of the distance between the pitches as much as N = 10. From the 10 measuring points of the thread pitch distance, different average values and deviation values will be produced although in the same size.. The purpose of this study was to determine the level of pressure of a thread made through a machining process which in this study used a CNC TONGTAI TCS 1500 [M] lathe. it is known that the overall average value of the three samples is with a major diameter = 14,949 mm, a minor diameter = 13,219 mm, and a thread pitch distance = 1.5309 mm.

<p>This thesis discusses the traditional use of (computer numerically controlled) CNC machining and the role of a designer to control the manipulation of (computer aided manufacturing) CAM software, CNC data and materials. The engaged designer has the capability to add qualities of digital tectonics onto a specified form through the process of working intimately with a CNC lathe. They experiment using abstract forms to find unique qualities that come from the cutting action of the tooling in a lathe. The designer takes on the role of the self-learner to become competent in the software, technology to apply complex textures and expressions. The designer can capitalise on unforeseen events, adds the action of craft to this industrial production method, creates beauty and provokes an emotional connection. Understanding the potential in the design possibility is to accept the serendipitous influences that can be controlled and the inevitable moments that cannot. The core of this research is to show how a designer claims authorship of their design at the making stage. They can define the margin of control and randomness, whether something has become too serendipitous, compromising the crafted form, or remained banal, repeating the precision machining, and releasing any character from the object. By finding the best design solution and replicating the same understanding a craftsperson has of their traditional tools. The designer observes, analyses, succeeds and fails, recognising the potential of their experimentation. Using Cross’s model of exploration, generation, evaluation and communication there is the strategy to see the unexpected, realise the potential and make it desirable. Learning the ability to manipulate digital surfaces and identify serendipitous qualities produced by the physical fingerprint of the machining process. Opposing the machines’ engineering, expressing the marks of the tool on an object, the imprints behaving as fingerprints left on a surface, is a unique characteristic. Something that makes the end user want to experience, feel, move and use it every day. These surprising results may influence the future of how design is conducted with digital technologies and adding digital complexities inspired by traditional craft to design more interesting artefacts.</p>

Studies and Practice of Geometrical Test Procedures & Reconditioning of CNC Lathe Machine Tool

Machining Centres have been major production units for many decades with desired levels of accuracy, economy in costs of production and ease of control. Though new disruptive technologies such as rapid manufacturing, near net shape manufacturing technologies are replacing these machining units, still small and medium Indian Industries go with the conventional ways of large-scale production using conventional and classical machining approaches. With huge setups in place, such machines with high productivity demands, require stringent parts alignment tests frequently from time to time, referred to as Geometrical or Alignment tests to enable accurate finishing and machining of parts and smooth and uninterrupted production. This paper puts forth some basic Geometrical Tests performed on SB CNC 60 Lathe Machine Tool unit, identifying major deviations measurements and reconditioning the machine parts. The main objective of running such tests is to prevent breakdown of the machine and ensure safety working when handling older and heavier conventional machines.

The Influence of CNC Turning with VBMT, RCMX, 3ER, and MGMN Type Indexable Inserts on West African Ebony/Diospyros Crassiflora, San Domingo Boxwood/Phyllostylon Brasiliense, Rio Rosewood/Dalbergia Nigra, Beechwood/Fagus Sylvatica, Oakwood/Quercus Robur, and Pinewood/Pinus Silvestris Surface Roughness

The current scientific literature lacks an adequate description of hardware used to machine timber. Traditional woodworking and metals fabrication consists of tungsten carbide (TC) inserts. In this work, the authors investigate the influence of cutting tool geometry on the resulting surface roughness of timber samples. A variety of wood types were used in these studies to provide broad information on the correlation between the cutting tools used and resulting surface morphology. The cutting tools were prepared on a computer numerical control (CNC) lathe and roughness average (Ra) and average maximum peak to valley height of the profile (Rz) parameters were measured by contact stylus. The tip radius of the TC inserts used was determined to be the most significant factor that impacted Ra and Rz. In summary, we found that the tip radius of the TC insert was inversely proportional to the roughness level, indicating that a flatter TC insert cutting end results in a smoother wood surface.
