Abstract:

Technological developments and advances in the digital era are currently growing rapidly along with the times, so that they have an impact in all sectors including the manufacturing industry sector. Competition in the manufacturing industry is getting higher, both in the field of supporting equipment technology and in the production sector. This makes all interested parties and companies compete to create more technical and practical equipment. The manufacture of equipment, parts, components and manufactured products in the past still used conventional machines such as lathes, milling machines, scrap machines and other machines in general and are still used today for certain jobs. The manufacture of parts such as shafts, factory components, heavy equipment components, car components, aircraft components and other engineering equipment components still uses conventional machines in a small part of the manufacture of parts and components. In jobs that require high production rates, short production times and high and uniform quality, using conventional machines is not recommended. Machines with CNC technology with computer-assisted numerical control or the like have been the solution for decades. In this paper, we will discuss the effectiveness of CNC machines, especially the TU-3A EMCO CNC milling as an illustration by developing G, M code programming, and product examples.

Abstract:

CNC turning is a popular machining process where material is removed from a rotating workpiece using a cutting tool. Productivity in CNC turning depends on parameters such as cutting speed, feed rate, and depth of cut. This paper presents an optimization approach using ANOVA to enhance production time, cost, and surface finish in CNC turning. The study examined the effects of cutting speed, feed rate, and depth of cut on machining Al 6351-T6 alloy. Key parameters were identified using ANOVA, and the multiobjective Particle Swarm Optimization (MOPSO) algorithm was employed to find optimal cutting conditions that minimize production time and cost while maximizing surface finish. A manufacturing time of 593.19 minutes, a manufacturing cost of Rs. 47.69, and a surface finish of 1.16 µm were achieved with the optimized parameters that included a feed rate of 0.107 mm/rev, cutting speed of 82 m/min, and depth of cut of 1.4 mm. This approach can significantly enhance CNC turning efficiency and reduce costs in manufacturing.

Abstract:

Bio-based composite films were produced by incorporating wood autohydrolysate (WH), chitosan (CS), and cellulose nanocrystals (CNC). In this work, WH was directly utilized without further purification, and CNC was introduced as the reinforced material to prepare WH-CS-CNC composite films with excellent properties. The effects of CNC on the properties of WH-CS-CNC composite films were investigated by characterizing their structures, mechanical properties, oxygen barrier, and thermal stability properties. The results suggested that CNC could improve tensile strength of the composite films, and the tensile strain at break could be up to 4.7%. Besides, the oxygen permeability of the prepared composite films could be as low as 3.57 cm3/day·m2·kPa, making them suitable for the food packaging materials. These above results showed that the addition of CNC is an effective method to enhance the toughness of composite films. In addition, WH-CS-CNC composite films have great potential in the field of sustainable food packing materials.

Abstract:

In todayâ€™s competitive and dynamic market environment, the main confront of metal-based industry is to maintain higher productivity and the surface excellence of the machined parts. In utmost situation, performance of turning process is measured in terms of quality of surface generated. Fatigue strength, corrosion resistance and creep life increases as superiority of turned surface improves significantly. Therefore ideal surface finish is usually required and appropriate parameters need to be selected to achieve required quality of surface. The present research intends to apply use of Taguchi method to carry out performance analysis of the CNC turned parts to achieve high surface finish on copper alloy material. This paper explores the corollary of process parameters in turning of copper alloy on HAAS CNC lathe machine.

Abstract:

In-process measurement and control of CNC machines can improve machining accuracy while increasing productivity and eliminating waste in a cost effective way. This paper describes an in-process measurement and control system called radial error feedback control (REFC) for bar turning in CNC turning centers. REFC was designed to compensate for the radial error due to the time-varying bar deflection caused by the cutting force, which moves along the bar at a constant velocity. In a dry cutting environment, a noncontact laser sensor was used to directly measure the radial error of the workpiece while it is being cut. To compensate for the radial error, a gain-scheduled Kalman filter for prediction together with PI control law was designed, based on a time-varying model of the deflection of the bar. Analytical modelling (using classical beam vibration theory) was employed to develop a simple model for the bar bending. For non-uniform bars finite element modelling can be used. Experimental results show that the dimensional and geometric accuracy of the workpiece is substantially improved by this radial error feedback control technique.

Abstract:

In present scenario CNC turning operation plays a vital role in metal based manufacturing industries. Therefore selection of optimum machining parameters, Tool geometry and cutting condition etc. for the variety of materials is an important and complicated task for the manufacturing industries in providing best quality at less cost to the customers. In this research work CNC turning operation is carried out using L<sub>9</sub> Taguchi orthogonal arrays on Naval brass C360 coated carbide insert and influence of CNC turning process parameters like Cutting Speed, Feed and Depth of Cut are analysed for two output objectives like material removal rate and surface roughness. The optimum sets of turning process parameter as well as combined effect of considered response are estimated using Taguchi technique application. In this analysis it is found that depth of cut has the largest effect on metal removal rate and feed rate has the largest effect on the surface roughness.It can be observed that depth of cut has the largest effect on metal removal rate and feed rate has the largest effect on the surface roughness of C360 brass by turning on CNC. The optimum turning condition for material removal rate isspindle speed (1600 rpm), feed rate (0.20 mm/rev.) and depth of cut (0.8 mm). The optimum condition for surface roughness is spindle speed (1400 rpm), feed rate (0.20 mm/rev.) and depth of cut (0.2mm).

Abstract:

Nowadays, glass fiber reinforced plastics (GFRP) composites play a vital role new line in many engineering applications as an alternative to various heavy exotic materials. Newline in GFRP polymeric composites, the matrix of polymer (resin) is reinforced with glass line fibers. Glass fiber reinforced plastics are increasingly used for variety of engineering new line applications from automobile to air craft components because of their superior new line advantages when compared to the other engineering materials. Turning of GFRP composite materials is a rather complex task owing to its heterogeneity and the number of problems. The Problems are surface delimitation, which appear during the machining process that is associated with the characteristics of the material and the cutting parameters. Optimization of machining parameters is an important process in machining. Experiments were conducted based on the established Taguchi’s technique L9 orthogonal array on a lathe machine. The cutting parameters are speed, feed rate, and depth of cut on the surface roughness, machining timing and material removal rate produced. The performances of the various parameters are evaluated by measuring surface roughness and material removal rate. The results indicate that the developed model is suitable for prediction of surface roughness and material removal rate in machining of glass fiber reinforced plastics composites. The percentage of contribution was analyzed speed parameter 80% for surface roughness feed parameter 66%for machining timing s and feed parameter 64% for MRR.

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:

The Computer Numerical Control (CNC) machine represents a turning point in today's production which has high requirements for product accuracy. The CNC machine enables a high flexibility in work and time saving and also reduces the time required for product accuracy control. Moreover, the CNC machine are used for several activities, most often for turning, drilling and milling operations. Usually, the productivity of any CNC machine can be increased thanks to the minimization of the non-productive of tool movement. In this paper, the results of a new metaheuristic named Dhouib-Matrix-4 (DM4) with an application on the NP-hard problem based on the Travelling Salesman Problem are presented. DM4 is used for increasing the performance of the CNC Machine by optimizing a tool path length in the drilling process performed on the CNC milling machine. The proposed algorithm (DM4) achieves a solution closed to the optimum, compared with the results obtained with the Ant Colony Optimization algorithm and the results found with the manual programming in G code by using a control unit for the selected CNC milling machine.

Abstract:

PT X is a manufacturing company that produces high-precision components, using 13 units of CNC machines as production tools. The target of achieving technical availability for each machine unit is at least 85% in one year. One of the machine units, namely the CNC vertical turning lathe machine in this company, was only able to reach 64% of the technical availability value due to the impact of the damage. This study aims to determine the causes of component failure in machine units that have low technical availability, namely the CNC vertical turning lathe, using the Failure Mode and Effect Analysis method. The results showed that during one year, the CNC vertical turning lathe was damaged 19 times, on 7 different machine components. With the results of data processing using the Failure Mode and Effect Analysis method, it is known that of the 7 components that were damaged, the component that had the highest risk priority number value was the electronic component with an RPN value of 405.

Abstract:

The primary aim of this study was to design and develop an on-line control system of finished surfaces in automated machining process by CNC turning. The control system consisted of two basic phases: during the first phase, surface roughness was monitored through cutting force signals; the second phase involved a closed-loop adaptive control system based on data obtained during the monitoring of the cutting process. The system ensures that surfaces roughness is maintained at optimum values by adjusting the feed rate through communication with the PLC of the CNC machine. A monitoring and adaptive control system has been developed that enables the real-time monitoring of surface roughness during CNC turning operations. The system detects and prevents faults in automated turning processes, and applies corrective measures during the cutting process that raise quality and reliability reducing the need for quality control.

Abstract:

The roundness is one of the most important criteria to accept the mechanical parts in the CNC turning process. The relations of the roundness, the cutting conditions and the cutting forces in CNC turning is hence studied in this research. The dynamometer is installed on the turret of the CNC turning machine to measure the in-process cutting force signals. The cutting parameters are investigated to analyze the effects of them on the roundness which are the cutting speed, the feed rate, the depth of cut, the tool nose radius and the rake angle. The experimentally obtained results showed that the better roundness is obtained with an increase in cutting speed, tool nose radius and rake angle. The relation between the cutting parameters and the roundness can be explained by the in-process cutting forces. It is understood that the roundness can be monitored by using the in-process cutting forces.

Abstract:

In the automotive industry, machining is an essential part of the production process. On mild steel, a turning process was utilised to create shafts of varied diameters. This work attempts to optimise multiple factors such as surface roughness, MRR, and tool wear during turning operations on various steel grades. The average surface roughness (Ra) is one of the most important measurements of surface quality during the machining process, and it is primarily influenced by a number of machining parameters such as true rake angle and side cutting edge angle, cutting speed, feed rate, depth of cut, nose radius, and machining time. The Taguchi technique was used to build a surface roughness model to study how machining factors such as feed rate, tool geometry, nose radius, and machining duration impact the roughness of the surface created during the dry turning phase. This study demonstrates how to determine surface roughness values for CNC turning of AISI 52100 steel with varying coated tool nose radius using tribiological parameters. The test was carried out on a commercial CNC machine with coated tool nose radiuses of 0.4, 0.8, and 1.2 mm. Further investigation revealed that the CNC machine's design had been completed in Solid Works. Static and modal analyses were carried out using ANSYS Workbench. A static structural analysis of a CNC machine was carried out using 1G lading, which met the minimum Yield Strength requirement.

Abstract:

This report discusses the configuration of some preparatory and auxiliary commands for the Fanuc 18i TB CNC system for a counter-spindle lathe using special macros called Vericut macros. In most cases, this is necessary because the Vericut library of machines and CNC systems does not have the specific machine and system or do not correspond to the actual ones, i. e. there is no match between them. The need to configure the CNC control system is related to the fact that it is possible to perform simulation, optimization and verification of control programs in a virtual environment before proceeding to the processing of workpieces on the real machine.

Abstract:

In the present day manufacturing scenario, computer numerical control (CNC) technology has evolved out as a cost effective process to perform repetitive, difficult and unsafe machining tasks while fulfilling the dynamic requirements of high dimensional accuracy and low surface finish. Adoption of CNC technology would help an organization in achieving enhanced productivity, better product quality and higher flexibility. In this paper, an endeavor is put forward to apply discriminant analysis as a multivariate statistical tool to investigate the effects of speed, feed, depth of cut, nose radius and type of the machining environment of a CNC turning center on surface roughness, tool life, cutting force and power consumption. Simultaneous discrimination analysis develops the corresponding discriminant function for each of the responses taking into account all the input parameters together. On the contrary, step-wise discriminant analysis develops the same functions while considering only those significant input parameters influencing the responses. Higher values of hit ratio and cross-validation percentage prove the application of both the discriminant functions as effective prediction tools for achieving enhanced performance of the considered CNC turning operation.

Abstract:

With STEP-NC (ISO 14649) being gradually accepted as new standard for programming computerized numerical control (CNC) machine tools, new technologies and computer systems in the design and manufacturing process chain are emerging, and conventional systems are reshaping, to support interoperable and intelligent manufacturing. This paper addresses issues and solutions for the adaptation. In the first place, a strategy for adapting legacy CNC turning machine tools to the emerging standard is presented. In the second place, the new data model is analyzed and a practical way to retrieve and extract manufacturing information from the STEP-NC part program for turning process is presented. In the third place a workable approach to calculating the cutting force and chip load in turning operations is presented based on the mechanistic modeling method. Finally the proposed approach is implemented in a prototype system and tested with an example STEP-NC program for turning, which shows not only the feasibility of the proposed approach for information extraction and process evaluation, but also the possibility of using simple transitional systems to bridge the gap between the sophisticated STEP-NC part program and conventional CNC machines.

Abstract:

Dalam industri manufaktur terdapat banyak yang menggunakan proses pemesinan seperti: mesin milling, mesin turning, mesin frais, dan lain-lain. Di dalam mesin milling merk Aciera terdapat part yang sering rusak yaitu Draw Bar yang berfungsi untuk memasang dan mengencangkan arbor pada kepala mesin. Pembuatan Draw Bar pada dasarnya dilakukan dengan proses turning CNC. Untuk mendapatkan Draw Bar sesuai produk yang aslinya, penulis mencoba melakukan penelitian untuk membuat Draw Bar dimulai dengan pemilihan material yang kekerasanya sama atau mendekati kekerasan Draw Bar aslinya dan proses pemesinan dengan melakukan variasi perubahan feed rate (kecepatan pemakanan) menggunakan mesin CNC turning type Tornado 100. Dari hasil analisis pengaruh feed rate terhadap kekasaran permukaan pada proses pembubutan Draw Bar meggunakan mesin CNC turning menunjukkan bahwa adanya pengaruh yang signifikan antara perubahan feed rate dengan hasil kekasaran permukaan Draw Bar dari hasil pengujian (eksperimen). Nilai hasil uji kekasaran yang di dapat adalah 1.91 µm dengan putaran spindle = 2400 RPM dan feeding 240 mm/menit. Dari hasil 21 uji coba kekasaran berarti semakin tinggi feed rate maka kekasaran permukaan Draw Bar yang dihasilkan akan semakin kasar. Hasil pengujian menggunakan surface roughness tester,pada bagian Draw Bar menunjukkan hasil permukaan pada part original nya adalah 1.90 µm.

Abstract:

In this study, simulation based on a theoretical model was made to investigate the influence of inertial effect and friction force to CNC machine’s accuracy and to explore the functions of related control parameters. By using empirical method, an auto-tuning system that can on-line tune the CNC control parameters based on the detected weight of workpiece was developed. In addition, an on-line weight identifying system was also developed. After integrating the two systems, an intelligent parameter-tuning system which can be directly implanted into CNC controller was developed. Experimental results have shown that the system can effectively improve the accuracy of a machine tool through on-line control parameter tuning.

Abstract:

The twin-screw vacuum pump is widely used in low and medium-low vacuum applications. Its core element consists of a pair of rotors rotating in opposite direction on parallel axes. Screw rotors with uniform pitch are usually finished by the form grinding method, but the rotors with variable pitch are not. In this paper, a manufacturing process for generating the tooth profile of the screw rotor with variable pitch by CNC lathe turning is proposed. The initial position of turning tool and normal profile error of the manufactured screw rotors are derived and verified numerically. Numerical examples are presented to validate the proposed method. The simulation results reveal that the proposed CNC turning process is feasible and flexible.

Abstract:

Contour turning is a specific process of the machining on CNC lathes. In the finishing operation, to create the part profile, the turning tool must be moved in a trajectory of a complex flat curve (a toolpath) based on the part profile . The variation of feedrate vector on the toolpath according to the part profile in the machining process will results in changing dynamic geometric parameters of the cutting tool, which affects cutting conditions and machined part quality. This article presents the results of theoretical studies on the influence of part geometry on rake angle, clearance angle, approach angle and end cutting-edge angle of the turning tool. Based on the theoretical development, the authors also set up mathematical expressions that allow to define gouge-free cutting condition and the limit of feedtate for contour turning. An empirical model to define the influence of part geometry on the roughness of the part when countour turning on CNC lathe is also presented in this report.

Abstract:

The paper presents the concept of a support system for the manufacture of machine spare parts. The operation of the system is based on a reverse engineering module enabling feature recognition based on a 3D parts scan. Then, a CAD geometrical model is generated, on the basis of which a machining strategy using the CAM system is developed. In parallel, based on the geometric model, a finite element model is built, which facilitates defining technological parameters, allowing one to minimize the risk of vibrations during machining. These parameters constitute input information to the CAM module. The operation of the described system is presented on the example of machining parts of the shaft class. The result is a replacement part, the accuracy of which was compared by means of the iterative closest point algorithm obtaining the RMSE at the level of scanner accuracy.

Abstract:

The surface roughness quality of machining product plays important role when it contacted with other machine components. That quality depends on several parameters setting, such as material, cutting tool, cutting condition and operator skill. The aim of this study is to obtain the optimum setting of turning parameters by using Taguchi method. Three control factors: cutting speed, depth of cut, and feeding at three different levels are selected. A series CNC turning process on AISI 1045 material were performed using L9 (3)3 orthogonal array with cutting fluid. Insert carbide cutting tool is used in the experiment. In order to reveal the optimum machining parameter, smaller the better is quality characteristic selected for surface roughness examination of workpiece. Analysis of experiment results revealed that higher cutting speed, low feed, low depth of cut respectively, provides fine surface quality of machined workpiece. Moreover, feed f parameter was found most influence to the surface rougness quality with 53.73% contribution, cutting speed v provides 23.28% contribution, and depth of cut a provides 17.87% contribution. Confirmation experiment shows that level 3 of cutting speed, level 2 of cutting depth, and level 1 of feed deliver smoothest machined surface of Ra 0,46 µm.

Abstract:

When turning many materials, especially such as high-alloyed steels and a some of non-ferrous metal alloys, long continuous chips are usually formed which clutter the working area of the machine tools and are dangerous for the workers. One of the effective and reliable methods of chip breaking during turning is vibration cutting, when the uniform motion of the cutter relative to the workpeace during the turning process is superimposed with an additional vibration motion of the cutter. The use of oscillating movements of the cutter in the direction of longitudinal feed is the most effective for chip breaking during longitudinal turning. To ensure the necessary amplitude-frequency range of cutter oscillations, the use of a toolholder with an elastic part in the form of a machined spring of cross slot configuration and directional stiffness. The toolholder is equipped with a mechanism of oscillating movements of the elastic part, which receives movement from the drive of the tool spindle of the machine tool. The development and research of the mathematical model of the cutting tool elastic system determined the conditions under which reliable chip breaking takes place regardless of the cutting modes and the properties of the processing material. The conducted experimental studies confirmed the effectiveness of the proposed toolholder with elastic elements for reliable chip breaking during longitudinal turning. Key words: chip breaking, vibration cutting, mathematical simulation, toolholder with machined spring of cross slot configuration.
