Abstract:

Insert conditions significantly influence the product quality and manufacturing efficiency of lathe machining. This study used the power spectral density distribution of the vibration signals of a lathe machining accelerometer to design an insert condition classification system applicable to different machining conditions. For four common lathe machining insert conditions (i.e., built-up edge, flank wear, normal, and fracture), herein, the insert condition classification system was established with two stages—insert condition modeling and machining model fusion. In the insert condition modeling stage, the magnitude features of the segmented frequencies were captured according to the power spectral density distributions of the accelerometer vibration signals. Principal component analysis and backpropagation neural networks were used to develop insert condition models for different machining conditions. In the machining model fusion stage, a backpropagation neural network was employed to establish the weight function between the machining conditions and insert condition models. Subsequently, the insert conditions were classified based on the calculated weight values of all the insert condition models. Cutting tests were performed on a computer numerical control (CNC) lathe and utilized to validate the feasibility of the designed insert condition classification system. The results of the cutting tests showed that the designed system could perform insert condition classification under different machining conditions, with a classification rate exceeding 80%. Using a triaxial accelerometer, the designed insert condition classification system could perform identification and classification online for four common insert conditions under different machining conditions, ensuring that CNC lathes could further improve manufacturing quality and efficiency in practice.

Abstract:

CNC (Computerized Numerical Control) lathes have become integral to modern manufacturing and machining industries due to their ability to produce intricate parts with precision and efficiency. Not only do CNC lathes enhance productivity and accuracy, but they also minimize human error and enhance overall safety in the manufacturing process. Furthermore, the current market offers a wide array of diverse types of CNC lathes. Consequently, the evaluation and selection of CNC lathes pose a complex decision-making challenge as there are numerous types available, each with a variety of selection criteria for manufacturers to consider. It is crucial to make an informed choice, as improper evaluation and selection can have adverse effects on the overall performance of the production system. In this study, we propose using the fuzzy EDAS (Evaluation Based on Distance from Average Solution) model to evaluate and select CNC lathes. Initially, we employ the fuzzy analysis method, based on expert opinions, to establish a set of weights for the evaluation criteria. These criteria consist of seven factors: capital cost, spindle speed, distance between centers, rapid traverse rates in the X-axis and Z-axis, maximum machining diameter, and maximum machining length. Subsequently, the fuzzy EDAS object ranking model is utilized to evaluate and rank the CNC lathes, ultimately aiding in the selection of the most suitable machine for the manufacturer. The results obtained from our analysis reveal that the MICROTURN-300DX machine is the optimal choice, closely followed by the MICROTURN-300X machine. The study's findings serve as valuable guidelines for decision makers in selecting CNC lathes that align with the requirements of factory production. Moreover, the suggested approach can also be utilized to choose various other machine types as production demands become more intricate

Abstract:

Introduction. The analysis of factory lathe-automatic operations revealed a significant variety of multi-tool setups and identified its areas of application. To develop a matrix theory of accuracy for multi-tool machining and create a unified algorithmic approach to errors modeling for all possible spatial multi-tool setups, it is necessary to consider the flexibility of the technological system in all coordinate directions. In this regard, it is required to systematize a large number of existing multi-tool setups and classify it to structure the information and improve the understanding of its application. Purpose of the work is to develop a classification of multi-tool setups on multi-carriage and multi-spindle CNC lathes, enabling the creation of both a matrix model of machining accuracy for each classification class and a unified generalized matrix model of machining accuracy for the entire classification class. The work investigates the systematics of multi-tool setups, oriented toward the development of matrix models of machining accuracy. Therefore, the classification considered in this work is aimed at identifying the characteristics of force loading and deformation of the technological system during multi-tool machining. The research methods involve identifying the parameters used for classification and the hierarchy of these parameters, which determines the levels and order of the systematics. Based on the principles of systematics of multi-tool setups used in traditional automatic lathes, an analysis of its adaptation to the capabilities of modern lathes designed for multi-tool machining is conducted. Results and discussion. As a result of the research, a formalized six-level classification of multi-tool setups is developed, which includes the following aspects: the method of workpiece mounting, the set of carriages, the types of cutting tools, the types and directions of carriage feeds, the orientation of cutting tools relative to the workpiece, and the method of tool engagement (parallel, sequential). This classification takes into account the technological capabilities for organizing multi-tool machining on modern CNC lathes. The main classes of the proposed systematics of multi-tool setups in the presented work include single-carriage single-coordinate setups, single-carriage two-coordinate setups, dual-carriage single-coordinate setups, dual-carriage two-coordinate setups, and multi-carriage setups. The proposed systematics of multi-tool setups on lathe group machines is aimed at developing machining accuracy models and can serve as a basis for developing recommendations on cutting modes for these CNC machines. The proposed classification of multi-tool setups forms the foundation of the methodological support for the CAD system of lathe-automatic operations and serves as the basis for creating next-generation CAD systems for lathe operations.

Abstract:

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.

Abstract:

Dynamic MRR (material removal rate) modeling is constructed and optimum solution through Calculus of Variations in maximize the machining profit of an individual cutting tool under fixed tool life is introduced. The mathematical model is formulated by reverse experiments on an ECOCA PC-3807 CNC lathe, and the electronic circuit is developed using linear regression technique for virtual machining. The inaccuracy between actual and simulated voltage is assured to be within 2%. By introducing a real-world CNC (computerized numerical control) machining case from AirTAC into the virtual system, the simulated cutting forces are shown to promise the feasible applicability of the optimum MRR control. Additionally, the implementation of dynamic solution is experimentally performed on a proposed digital PC-based lathe system. The surface roughness of all machined work-pieces is found to not only stabilize as the tool consumed, but also accomplish the recognized standard for finish turning.

Abstract:

There are many ways of machining gears; the world’s manufacturers of machine tools have patented many methods that allow for the production of gears in an accurate and efficient way. In general, the patented methods require the use of kinematically complex and expensive CNC machine tools. These tools, moreover, the production of the technology itself, including the machining code, require the use of dedicated software. Therefore, it seems justified to strive for the application of kinematically simple and relatively cheap machines in the machining processes so as to increase the universality and availability of new machining methods. This paper presents a method of machining a spur gear with straight teeth with an involute profile using a basic CNC lathe DMG MORI CLX350V4 equipped with driven tools. On the basis of the presented mathematical model, an algorithm was developed to generate a code that controls the machining of cylindrical gears with an involute profile of straight teeth, with the possibility of modifying the transition profile and the tooth root. The machining was experimental, and the gear was made of aluminium AlSi1MgMn using a solid carbide cylindrical cutter. In conclusion, the presented method was found to be very competitive with commercial methods and is able to provide very high quality gears. The accuracy of the machined profile form deviation in the entire processing did not exceed an average value of 10 μm; while assessing the tooth line, the basis average error was 5 μm. Finally, the gear was assessed as manufactured in accuracy class 6. This machining method guarantees very competitive machining cycle times, and thanks to the use of an uncomplicated CNC lathe and universal tools, it provides great flexibility, at the same time giving the possibility of machining gears with arbitrary profiles.

Abstract:

Cutting fluids are used in manufacturing processes to reduce friction, control heat generation, and extend tool life by providing heat absorption, lubrication, and cooling. Achieving higher productivity and quality in manufacturing is a significant challenge, with modern methods like CNC turning playing a critical role in addressing this challenge. The objective is to optimize CNC turning parameters specifically for machining EN19 alloy steel, which is widely utilized in automotive and machine tool industries. The goal is to enhance surface finish without sacrificing productivity. This requires strategic implementation of Dry machining, Minimum Quantity Lubricant (MQL), Flood Cooling, and Liquid Nitrogen Bath (LBN) techniques. Machining parameters such as cutting speed, feed rate, and depth of cut also play a crucial role in improving surface finish. Experimentation involves varying these parameters across different levels while applying all three lubrication conditions to determine their impact on surface finish. The most effective combination of machining parameters and lubrication methods can be identified through systematic testing and analysis to optimize surface finish while maintaining productivity in the CNC turning of EN19 alloy steel.

Abstract:

The role of automatic machining with the help of computer programming such as Computer Numerically Controlled (CNC) has become commonplace today in both large and small industrial sectors or micro industry. CNC is a manufacturing process where previously programmed computer software is converted into code that can automate machining movements, one of which is the milling or lathe process. CNC performance is determined by machining output power. For micro industrial or laboratory scale, CNC with low power is usually used to cut soft materials such as wood, acrylic, aluminum and others. This is the basis for this research to look at the influence of machining parameters such as speed, depth of cut and feed rate on the surface roughness (Ra) of AI6061BE aluminum workpieces in the dry machining process on a mini CNC unit with a maximum spindle power of 500 watts. This research uses an experimental design based on the Taguchi method and takes the form of an L16 (43) orthogonal matrix. The chisel used is a Straight End Mill 2 fluke carbide chisel. The experiment was carried out 4 times cutting in the positive x-axis direction and 4 times in the negative x-axis direction for each variation of machining parameters. From the test results, surface roughness, feed rate is a parameter that is more influential than speed and depth of cut.

Abstract:

Abstract: Products are manufactured using modern technology nowadays that uses communication between computer software, hardware and firmware, and lathes play an important role in production. While manual machine lathes are more economical, they have to be made by skilled workers, which limits their precision and poor performance, on the other hand, CNC machines provide the accurate and good results needed, but cost a lot of money. This can be done using ARM. The processor is used to control the work of the lathe. Retrofit is a way to use new technologies and features to improve the performance and security of legacy systems. Since the machining process takes a long time, retrofit applications can be made on traditional lathes. Also, in this traditional turning job, the results are not the same as the result of the work piece depends on the skill of the operator. For this reason, a new design has been created to maintain this lathe and increase its lifespan. Rebuilding and remanufacturing often involves CNC rebuilds.

Abstract:

In the industrial sector, technological progress has experienced very rapid development. So that the manufacturing industry is required to be able to produce quality products and a high level of accuracy with fast processing. One machine that can meet these demands is a CNC lathe, where a CNC lathe is a machine that is controlled using a computer system in its operation. In the machining process of CNC lathes, the level of surface roughness of the machining material is of great concern, because the lower the surface roughness value, the better the quality of the product. Therefore, the aim of this study was to obtain a low surface roughness value using a finishing cutting edge. The material used is AISI 1045 steel which is turned using a MORI SEIKI SL-25 CNC machine. The parameters used are spindle speed and feeding. The research method used was the Taguchi method with an orthogonal matrix L9(32) experimental design and 3 replications were carried out to reduce large deviations. The result of this research is to obtain a combination of parameters that produce minimum surface roughness values, namely spindle speed of 1804 rpm and feeding of 0.1 mm/put. And the parameter that has the greatest effect on the value of roughness is feeding with a difference of 16.029 and the one that has the least effect on the value of surface roughness is spindle speed with a difference of 1.384.

Premium connection has high quality requirements on thread and sealing surface and needs to be machined by CNC lathe. Using loop program in CNC machining has advantages in reducing memory occupying, cutting the computational procedure and simplifying program. However, the processing profile curve often has a special shape. As a result, the idle motion of tools is increased and the production efficiency would be lowed. The paper studies the two procedures of rough turning process and finish turning process in a new gas tight premium connection machining. An improved method is developed by which the idle motion of tools is reduced and the machining efficiency is improved. The good result in the field application indicates that the improved method is practical.

Abstract:

It is shown that the turning of the contour shaped surfaces of parts is mainly carried out according to the cycles of rough turning G71, G72, G73 with a finishing pass according to the cycle G70. In any case, the cutting process is quasi-stationary, which determines the need to control the cutting mode to stabilize and optimize the process. It is proposed to use a special program for designing the control program of a CNC machine tool, which, based on a priori information about the technological machining system, performs the simulation of the process. During simulation, in the process of solving the optimization problem according to the criterion of maximum Material Removal Rate, all components of the cutting mode are automatically determined: depth, feed and spindle speed. The results are presented in the form of control files, according to which a control program in G-codes can be compiled to optimize the process. In addition, it is additionally possible to obtain a prediction about the actually machined contour, taking into account the elastic deformation during the cutting process, and data on the correction of the trajectory of the shaping movement in the last pass.

Abstract:

Computer numerical control (CNC) lathes are optimized for machining workpieces into rotating shafts or cylindrical shapes of structures. However, because rotating mechanical parts are used on CNC lathes, vibration from spindles, servomotors, hydraulic pumps, and feed screws occurs. Therefore, periodic preventive maintenance is required to minimize vibrations. Additionally, alignment, balance, and adjustment operations are necessary for parts that perform linear or rotational movements. Thus, this study adjusts the tension of the V-belt that drives the spindle of the CNC lathe, analyzes the primary components and the vibrations occurring at the spindle and servomotor, and measures the surface roughness to identify the cutting quality according to the impact of the belt tension. The experimental results show that the peak value of the vibrating component increases as the cutting speed increases. We demonstrate that the optimal vibration characteristics and excellent surface roughness values are achieved at a relatively looser belt tension than the standard value. In particular, at a feed speed of 0.05 mm/rev, a cutting speed of 250 m/min, and a depth of cut of 0.8, the surface roughness in loose tension was reduced by up to 143.9% compared to tight tension. Additionally, the optimum processing quality is achieved at a cutting depth of 0.6 and 0.8 mm, corresponding to a turning insert nose R-value of 0.4 mm, and at cutting speeds ranging from 200 to 250 m/min.

For example in the machining process, one of which is CNC lathe machining, the level of roughness of a product really needs to be reviewed. The minimum surface roughness shows that the quality of a CNC machining process is very good, because the smaller the surface roughness value, the greater the quality value of a product, therefore in order to achieve this goal it is necessary to set the right parameters. Parameters varied were spindle speed (Rpm) and feeding. In this study the method used is the experimental method, with a combination of parameters to obtain surface roughness values. The material used is AISI 1045 steel, with the results of the data being analyzed using the Taguchi Smaller the Better method in Minitab 21.3 software. From the results of the calculation of the mean factor, the percent contribution to the spindle speed was obtained at 56.28%, while at feeding it was obtained at 38.14%. The optimal roughness value is obtained from the combination of parameters in the CNC lathe process on AISI 1045 steel which can make the optimal response value obtained at a spindle speed of 1645 rpm and a feeding of 0.18 mm/rev.

To fit the crank non-circular contour, uses the high frequency linear servo motor to drive the tool move to-and-fro with high frequency, so the tool will track the crank non-circular contour with real time. With the results of several experiments for time-base following control with displacement feedback, the feasibility and efficiency of Open CNC system are verified.
