Resumen

Abstract Tendencies towards increasing cutting speeds during machining can be observed recently. The first wave of increasing cutting speeds occured in the 60s of the previous century. However, suitable tool material was not available at that time. Increasing cutting speed is possible only following the development of cutting material, resistant against high temperatures, abrasive, adhesive and diffusive wear. It is obvious that the process of chip creation, quality of machined surface, dynamics of machining process and temperature of cutting change considerably with cutting speed. To be able to apply higher cutting speeds in production machining, it is necessary to know the dependence of those characteristics on cutting speed. Some of those phenomena, which are linked with cutting speed, will be explained in the paper. Key words: machining, cutting speed, tool durability, surface quality

Resumen

The focus of the majority of high-speed machining research has been directed toward improving metal removal rates. Tool materials capable of withstanding high cutting speeds have become available (silicon nitride for cast iron, solid carbide for aluminum, and superabrasives for hardened steels), and the focus of research has shifted to maximizing the cutting performance of the machine tool. Measurement of cutting performance, chatter avoidance, structural design, tool retention, and axis control have become important research topics. The purpose of this paper is to provide an overview of the state of the art in high-speed machining and to provide our view of the emerging research areas.

Resumen

This paper gives the details of High Speed Milling experiments with AISI 52100 steel (HRC52) by using coated carbide end mills. Cutting force and Surface roughness data are presented. The effects of cutting speeds (1000-8000rpm), widths of cut (0.05-0.4mm) and cutting conditions (dry cutting and dry cutting with air coolant) are investigated. The results show that in high speed milling of hardened steels, when cutting speed surpasses a critical value, cutting forces decrease as cutting speed increasing; and the increasing of widths of cut causes the increase of cutting forces approximately linearly; surface roughness does not experience obvious increase or decrease and has a minimum in a specific condition; the machining results of dry cutting with air.

Resumen

High-speed machining has become mainstream in machining manufacturing industry. In industries such as moldmaking and aerospace, it has become the norm rather the exception. The centrifugal force increases as the square of the speed. At rotational spindle speeds of 6,000 r/min and higher however, centrifugal force from unbalance becomes a damaging factor and it reduces the life of the spindle and the tool, as well as diminishes the quality of the finished product. Under high rotational speed, good balance becomes issue. High-speed machining experimental results shown that a well-balanced tool/toolholder assembly could obviously improve machining quality, extend tool life and shorten downtime for spindle system maintenance etc.

Resumen

This paper presents a methodology for determining the machine tool system requirements for high-speed machining (HSM)/high-throughput machining (HTM). Both technological and economic factors should be considered in the formulation of the model for determining machine tool system requirements. The HSM function model is given here in the form of ICAM-defined (IDEFo) charts with corresponding text. For machining most aluminum alloys, the maximum cutting speed is not limited by tool life, and the technology for high-speed machine tools (spindles, table drives, controls, chip management, and other features) exists today. Therefore, HSM of aluminum alloys can be implemented. Selection of a suitable HSM system involves detailed technological analysis and economic justification for a given part-family production configuration. The recent introduction of Si3N4 based tool materials has enabled significantly higher cutting speeds (up to 1524 mpm or 5000 sfpm) in the machining of gray cast iron. However, the machine tools using this type of tool material should be more rigid and capable of higher power, higher speed, and faster feed in order to increase productivity and reduce manufacturing costs. In the machining of the difficult-to-machine materials (e.g., superalloys), the cutting speed is still limited by tool wear. Nevertheless, a high-throughput machining (HTM) strategy is pertinent for this application.

Resumen

Elimination of chatter is an important problem for the successful implementation of high speed machining. Chatter is often related to the dynamic characteristics of the spindle system. The current study addresses the dynamic characteristics of angular contact bearings, which are the most commonly used type for high speed spindles, with respect to the speed change at high speeds, and reveals a very important fact on how the stiffness changes with respect to the speed change. It also illustrates how this characteristic is related to the system stability. Both analytical and experimental results show that there is a substantial change in stability zones in the high speed range and that the speed varying dynamic characteristics of a spindle must be properly taken into consideration in order to select a stable machining speed in high speed machining.

Resumen

Removal rates for machining titanium alloys are an order of magnitude slower than those for aluminum. The high strength and hardness coupled with the relatively low elastic modulus and poor thermal conductivity of titanium contribute to the slow speeds and feeds that are required to machine titanium with acceptable tool life. Titanium has extremely attractive properties for air vehicles ranging from excellent corrosion resistance to good compatibility with graphite reinforced composites and very good damage tolerance characteristics. At current Buy to Fly ratios, the F-35 Program will consume as much as seven million pounds of titanium a year at rate production. This figure is nearly double that of the F-22 Program, which has a much higher titanium content. As much as 50% of the final cost of titanium parts can be attributed to machining. Specifically, in this task, we are working to improve the material removal rate of titanium to reduce cost. Lockheed Martin is evaluating the potential to use lasers to heat the material ahead of the tool to reduce its strength. Coupled with other technologies that can improve the tool life and prevent the titanium material from welding to the tool, there is hope for a practical solution using similar milling machines to those which exist today, if not a simple retro-fit option. This presentation will present the current progress of this project and its potential impact to the Joint Strike Fighter.

Resumen

A forecasting speed smoothing algorithm based on inflexion velocity has been presented in this paper. According to the geometry characters of the machining trajectory, the inflexions in CNC machining tool path can be confirmed by using the designed algorithm. The line segment between each inflexion can be treated as a continuous path that can be tracked under the continuous feed rate. Moreover the maximal permitted link-up speed can be calculated through dynamic restriction equations and the real-time modification of sinusoidal acceleration can be realized by using the speed iteration algorithm. By simulation analysis, it can be revealed that both the flexibility and efficiency of the CNC machining has been improved and the impact to the machine tool has been greatly reduced.

Resumen

Progress in the production of cutting tools, CNC machine tools, and CAM software has contributed to improvement in subtractive machining processes, including milling, the so-called high speed cutting (HSC) and high performance cutting (HPC) machining. The cutting parameters that define the boundaries between the aforementioned technologies and conventional machining are not clearly defined. This is due to the close correlation between the process conditions and the types of processed material. High speed cutting and high performance cutting can be used for processing such as: machining of materials in the hardened state, machining without cutting fluid and with minimal lubrication, and thin-wall integral aerospace structures. The study examined complex analyses of HSC machining due to the process stability. The test results prove the dominant influence of cutting speed changes on a method’s effectiveness for spindle speeds up to 80,000 rpm.

Resumen

The robotic machining is one of the most versatile manufacturing technologies. Its emerging helped to reduce the machining cost of complex parts. However, its application is sometimes limited due to the low rigidity of the robot. This low stiffness leads to high level of vibrations that limit the quality and the precision of the machined parts. In the present study, the vibration response of a robotic machining system was investigated. To do so, a new method based on the variation of spindle speed was introduced for machining operation and a new process stability criterion (CS) based on acceleration energy distribution and force signal was proposed for analysis. With the proposed method the vibrations and the cutting force signals were collected and analyzed to find a reliable dynamic stability machining domain. The proposed criterion and method were validated using data obtained during high speed robotic machining of 7075-T6 blocks. It was found that the ratio of the periodic energy on the total energy (either vibrations or cutting forces) is a good indicator for defining the degree of stability of the machining process. Besides, it was observed that the spindle speed with the highest ratio stability criterion is the one that has the highest probability to generate the best surface finish. The proposed method is rapid and permits to avoid trial-error tests during robot programming.

Resumen

The trend towards increased machining automation improves plant utilization by reducing the nonmachining component of the production cycle and places a premium on reducing machining time. Improved tooling systems allow increased production rate with existing plant and equipment and result in increased production at negligible additional cost. Whereas new tool materials have traditionally been developed empirically, the state of understanding of the mechanisms of tool wear has advanced considerably in recent years. Therefore, an attempt has been made to identify specific strategies for developing new tooling systems for high speed machining in the light of current knowledge.

Resumen

Purpose Even though austenitic stainless steels have been extensively used in industries, owing to some of the characteristics of the material, its performance in machining is difficult to understand, in particular at high cutting speeds. There is no availability of dependable and in-depth studies pertinent to this matter. In this work, performance of AISI 304 austenitic stainless steel was studied in terms of surface roughness (Ra) and material removal rate (MRR) at high cutting speeds. Subsequently, parametric optimization and prediction for responses were carried out. Design/methodology/approach Turning operations were conducted using L9 orthogonal array and the outcomes were analyzed to attain optimal set of machining parameters for the responses using signal-to-noise (S/N) ratio and Pareto analysis of variance (ANOVA). In the present work, the cutting speed values were considered beyond the recommended range as designated by tool manufacturers. Finally, multiple regression models were developed to predict responses. Findings From the results, 350 m/min was found to be a significant speed. The investigation reveals that even though the speeds are taken beyond the recommended values, the results are favorable. The optimal machining parameters values for surface quality obtained were cutting speed of 350 m/min, feed of 0.15 mm/rev and depth of cut of 2.0 mm. In case of MRR, the optimal values were: cutting speed of 400 m/min, feed of 0.25 mm/rev and depth of cut of 2.0 mm. It was found out that there was an improvement in Ra and MRR (around 15 and 4%) due to optimization. The results indicate that Pareto ANOVA is easier than S/N ratio. This revealed that the feed rate and depth of cut were mostly affected parameters for Ra and MRR. The developed models are capable of predicting the responses accurately. Practical implications The outcome of the work reveals that even though the speeds were taken beyond the recommended value, the results are favorable for manufacturing industries when the tool cost is considered insignificant. Originality/value No work was reported on machining of the chosen material beyond the recommended cutting speed. Moreover, it was observed from the past works that cutting speeds were limited to 100–300 m/min.

Resumen

This paper summarizes tapping characteristics at speeds as high as 9,000 rpm (180 m/min surface speed) as compared to traditional tapping done at speeds from 500 to 1,500 rpm (20–30 m/min). High speed tapping was achieved by synchronizing the spindle rotation and the feed motion of a specially built machine at extremely high speeds and acceleration/deceleration rates. This investigation analyzes the performance of roll and cut tap geometries in the high speed tapping of 319 aluminum. The torque required by the different tap geometries at several speeds and percent threads combination is evaluated. The relationship between pretapped hole diameter and minor diameter of the thread and the estimation of percent thread are analyzed. The thread quality generated at high speeds is also evaluated. It is shown that the cutting speed does not affect the steady state torque and the shear strength. The torque for roll forming taps is higher than that for cut taps. The shear strength of roll forming threads increased with percent thread.

Resumen

At present, both preliminary and final HSM is recommended to be carried out according to the scheme of cut-down milling. Processing of reinforced and unreinforced polymers is also recommended to be carried out at cut-down travel. The main problem associated with cutdown milling is caused with insufficient dynamic stiffness or the presence of backlash in the feeder table. The proposed concept of machining allows eliminating fundamentally the influence of dynamic stiffness and the presence of backlash in the table feeding mechanism on the quality of machining with GUS makes it possible while retaining the advantages of cutdown milling. Some kinematic schemes for high-speed machining by milling and turnmilling are given in the paper. The schemes for forming geometrical roughness components in such machining and calculation formulas are presented. The results of experimental studies of roughness formation with disc cutters made of fiberglass composite material in high-speed machining are presented. The results obtained are compared with the calculated data.

Resumen

High-speed machining is considered to be a promising machining technique due to its advantages, such as high productivity and better product quality. With a paradigm shift towards sustainable machining practices, the energy consumption analysis of high-speed machining is also gaining ever-increasing importance. The current article addresses this issue and presents a detailed analysis of specific cutting energy (SCE) consumption and product surface finish (Ra) during conventional to high-speed machining of Al 6061-T6. A Taguchi-based L16 orthogonal array experimental design was developed for the conventional to high-speed machining range of an Al 6061-T6 alloy. The analysis of the results revealed that SCE consumption and Ra improve when the cutting speed is increased from conventional to high-speed machining. In particular, SCE was observed to reduce linearly in conventional and transitional speed machining, whereas it followed a parabolic trend in high-speed machining. This parabolic trend indicates the existence of an optimal cutting speed that may lead to minimum SCE consumption. Chip morphology was performed to further investigate the parabolic trend of SCE in high-speed machining. Chip morphology revealed that the serration of chips initiates when the cutting speed is increased beyond 1750 m/min at a feed rate of 0.4 mm/rev.

Resumen

This paper presents a residual stress prediction model for high-speed machining using the finite element method in conjunction with neural network. The finite element method is utilized to simulate a chip formation process, which is constituted step by step from the workpiece removal process under the conditions of high-speed machining. The residual stress distributions underneath the machined surface of the workpiece are determined subsequently. The artificial neural network is in turn applied to synthesize the data calculated from the finite element method and a prediction model for residual stress distributions within the machined subsurface of the workpiece is thus constructed. The model can predict the residual stress distributions at different locations beneath the machined surface of the workpiece for various workpiece materials under different combinations of cutting conditions such as cutting speed, feed rate, rake angle and edge radius of the tool more effectively.

Resumen

The dynamics of chip formation during high-speed orthogonal machining (planing) is examined. Merchant’s vector diagram of the forces acting upon the continuous chip free body is expanded to include inertial force components. Expressions are developed for cutting force and pressure. Energy balances are used to show that Merchant’s classical equation relating shear angle φ to rake angle α and friction angle τ applies, independent of cutting speed. Apparent differences between experimental observations of shear angle φ and Merchant’s prediction are attributed to workpiece material anisotropies, tool wear, built-up edge, and inaccurate measurement of the friction coefficient at the tool–chip interface. It is shown that good experimental values of the shear angle and friction coefficient may be obtained by measuring cutting pressure, utilizing dynamic material properties data, and invoking Merchant’s relation to resolve the energy balance. Continuous and segmented chip formation are contrasted. Melting in the tool–chip interface is verified.

Resumen

High-speed machining (HSM) has received great interest because it leads to an increase of productivity and a better workpiece surface quality. However, tool wear increases dramatically due to the high temperature at the tool/workpiece interface. Proper selection of cutting tool and cutting parameters is the key process in high-speed machining. In this paper, experiments have been conducted to high speed milling pearlitic cast iron with different tool materials, including polycrystalline cubic boron nitrogen, ceramics and coated cemented carbides. Wear curves and tool life curves have been achieved at various cutting speeds with different cutting tools. If efficiency is considered, Polycrystalline Cubic Boron Nitrogen cutting tool materials are preferred in finish and semi-finish machining. According to the different hardness of cast iron, the appropriate range of cutting speed is from 850 m/min to 1200m/min.

Resumen

Minimal quantity lubrication (MQL) machining has been accepted as a successful semi-dry application because of its environmentally friendly characteristics and satisfactory performance in practical machining operations. However, seldom investigation has been done in MQL machining of titanium alloy at high cutting speeds. In this paper, high speed milling experiments with MQL9 ml/h of oil in a flow of compressed air have been carried out for a widely used titanium alloy Ti6Al4V. Uncoated cemented carbide inserts have been applied in the experiments. Within the range of cutting speeds employed (190 m/min~300 m/min), the cutting performance of MQL has been investigated when peripheral milling the titanium alloy Ti6Al4V in terms of cutting forces, surface roughness, tool life and wear mechanism. The results show that, compared to dry machining, MQL machining brings about a significant reduction in cutting forces and surface roughness, and it also gives rise to a notably prolonged tool life.
