Abstract:
Ball screws are the driving components used to convert the rotational motion into linear motion in precision equipment. However, the machining accuracy of precision equipment is directly determined by the positioning accuracy of the ball screw. The authors analyze the precision sustainability of preload double-nut ball screws with raceway wear. A new wear model combining the modified Archard theory and the iterative interpolation method is established to analyze the variations in wear depth. A new model considering the coupling relationship between raceway wear and preload loss is proposed to study the precision life of the double-nut ball screw. In addition, a novel running test bench is designed to verify the precision sustainability of ball screws. The precision sustainability of the ball screw is analyzed during its life cycle, and these results match the theoretical values obtained by using the wear model.

Abstract:
Purpose This paper aims to examine the precision loss of ball screw raceway under different operating conditions and geometry parameters. Design/methodology/approach Based on a new coefficient K’ introduced especially for ball screws to reflect the actual contact condition, the modified Archard theory is applied to ball screws to obtain wear volume of the ball-screw contacts. Thus, the axial precision loss can be defined as the ratio of the wear volume to the contact area. Meanwhile, a novel running bench and a precision-measuring system of ball screws are conducted. Precision variation is obtained and analyzed during the whole life running test, which agrees well with the theoretical values calculated in this paper. Findings For a given rotational speed, the increasing rate of the precision loss rate is high at low axial load and then becomes small with the increasing axial load, whereas for a given axial load, the precision loss rate is proportional to the rotational speed. Besides, the precision loss rate is reduced with the increasing contact angle between a ball and the screw raceway, and is proportional to the helix angle when the angle changes from 1 to 10 degrees. Research limitations/implications The rotational speed used in this experiment is low and the ball screw is of no-load type, although results calculated by the model and Wei’s model seem close when the axial load is high, whether the model built in the paper is applicable to the condition of high rotational speed and preload still needs to be verified in the future work. Practical implications This study provides an accurate model to predict the precision loss of the screw raceway and estimate the remaining life of ball screws, which is significant for better performance of ball screws as well as the computer numerical control machine tools. Originality/value Previous studies on the wear of ball screws mainly focused on the drag torque analysis and mechanical efficiency estimation, and the experiment to verify their theoretical analysis was almost all limited to the test of drag torque or axial rigidity, which is neither sufficient nor persuasive. However, in this paper, the authors proposed a comprehensive wear prediction model which combines the modified Archard wear theory, Hertz contact theory and kinematic theory of ball screws. To the best of the authors’ knowledge, this kind of study has never been reported in the literature. In addition, for the lack of the test bench and high cost of the experiment, the whole life operation test, which is designed and conducted to confirm the model in this paper, has never been reported in literature either.

Abstract:
Double-nut ball screws bear the action of bidirectional pretightening force, leading to the deformation of the contact area between the ball and the raceway. Under this condition, it is important to analyze and calculate the static stiffness of the ball screw. However, the conventional calculation method is inaccurate. Hence, a new method for the static stiffness analysis of a double-nut ball screw is proposed. Through the structural analysis of the ball screw and internal load distribution, a load deformation model was established based on the Hertzian contact theory. Through the load analysis of the ball screw, a static stiffness model of the ball screw was established and applied to a case study and a finite element simulation. The rigidity of THK double-nut ball screws used in the X-axis feed system of a high-stiffness heavy-duty friction stir welding robot (developed by the research group) was calculated. When the workload was lower than 1.1 × 104 N, the slope of the double-nut static stiffness curve increased significantly with the increase in the workload, and when the workload was greater than 1.1 × 104 N, its upward slope tended to stabilize. The simulated and experimental stiffness curves were in good agreement; when the external axial load was greater than 2.8 × 104 N, the stiffness value calculated using the finite element method gradually converged to the theoretical value; and when the axial load reached 3.0 × 104 N, the simulation and test curves matched well. The analysis method of the double-nut ball screw was found to be concise and accurate, and the stiffness curves calculated using the two methods were consistent. The simulation analysis of the static stiffness presented herein is expected to aid the design of double-nut ball screws of high-rigidity heavy-duty equipment.

Abstract: In high-speed precision machining, thermal deformation caused by temperature rise affects the accuracy stability of the machine tool to a significant extent. In order to reduce the thermal deformation of ball screws and improve the accuracy, a new adaptive method based on carbon fiber reinforced plastics (CFRP) was proposed in this study and the thermal deformation of ball screws was determined. By using the sequential coupling method, the thermal–structural coupling analysis of a ball screw was conducted based on the finite element method (FEM). The analysis results were verified through a comparison with the experimental results. Based on the verification, an FE model of the improved ball screw was established to study its thermal characteristics. The key design parameters of the improved ball screw were optimized based on the Kriging model and genetic algorithm (GA). The thermal reduction effect of the improved ball screw was validated through the experimental results. The results indicate that the adaptive method proposed in this research is effective in reducing the thermal deformation of ball screws.

Abstract:
Ball screw is the driving functional component most frequently used for the precision equipment. To a certain extent, the transmission accuracy of precision equipment is affected by the position error of ball screw caused by the elastic–plastic deformation between ball and raceway under the overload impact. This article aims to investigate the precision loss of ball screw considering short-time overload impact. A novel precision loss model combining the Hertzian and Thornton contact theories is established to describe the variations in the axial deformation depths. Thus, the axial precision loss can be defined as the differential value between the initial no-loading travel variations and the loading stroke variations caused by the axial plastic deformation of raceway. Meanwhile, the maximum stress and the residual plastic deformation for four couples of ball-raceway materials are analyzed. Furthermore, the relationship between the precision loss and the elastic–plastic deformation is studied by the theoretical analysis and experiments. The results show that the position and precision is affected indeed by the contact deformation. The position and precision loss of the nut relative to the screw increases with the increase in the axial load. The results can help to provide the prediction for the precision life of ball screw operating in high-load condition.

Abstract:
In the construction of high performance mechanical transmission with high precision in movement and positioning are used ball screws with preloaded double nuts. Among the factors that influence the performance of these transmissions are friction idle torque and friction load torque. Because, theoretically, the friction idle torque is influenced only by the preload force that loading, the double nut of the ball screw, was experimentally determined dependence of that torque of screw speed. Given the set was determined and exposed in the present work, the relation of dependency, idle friction torque, preload force and screw speed. From the relationship thus obtained can determine the instantaneous friction coefficient of the ball screw, a value that is found in the expression of power lost through friction - default transmission efficiency.

Abstract:
Industrial demands for higher productivity rates and more stringent part tolerances require faster production machines that can produce, assemble, or manipulate parts at higher speeds and with better accuracy than ever before. In a majority of production machines, such as machine tools, ball screw drives are used as the primary motion delivery mechanism due to their reasonably high accuracy, high mechanical stiffness, and low cost. This brings the motivation for the research in this thesis, which has been to develop new control techniques that can achieve high bandwidths near the structural frequencies of ball screw drives, and also compensate for various imperfections in their motion delivery, so that better tool positioning accuracy can be achieved at high speeds. A precision ball screw drive has been designed and built for this study. Detailed dynamic modeling and identification has been performed, considering rigid body dynamics, nonlinear friction, torque ripples, axial and torsional vibrations, lead errors, and elastic deformations. Adaptive Sliding Mode Controller (ASMC) is designed based on the rigid body dynamics and notch filters are used to attenuate the effect of structural resonances. Feedforward friction compensation is also added to improve the tracking accuracy at velocity reversals. A bandwidth of 223 Hz was achieved while controlling the rotational motion of the ball screw, leading to a servo error equivalent to 1.6 um of translational motion. The motor and mechanical torque ripples were also modeled and compensated in the control law. This improved the motion smoothness and accuracy, especially at low speeds and low control bandwidths. The performance improvement was also noticeable when higher speeds and control bandwidths were used. By adding on the torque ripple compensation, the rotational tracking accuracy was improved to 0.95 um while executing feed motions with 1 m/sec velocity and 1 g acceleration. As one of the main contributions in this thesis, the dynamics of the 1st axial mode (at 132 Hz) were actively compensated using ASMC, which resulted in a command tracking bandwidth of 208 Hz. The mode compensating ASMC (MC-ASMC) was also shown to improve the dynamic stiffness of the drive system, around the axial resonance, by injecting additional damping at this mode. After compensating for the lead errors as well, a translational tracking accuracy of 2.6 um was realized while executing 1 m/sec feed motions with 0.5 g acceleration transients. In terms of bandwidth, speed, and accuracy, these results surpass the performance of most ball screw driven machine tools by 4-5 times. As the second main contribution in this thesis, the elastic deformations (ED) of the ball screw drive were modeled and compensated using a robust strategy. The robustness originates from using the real-time feedback control signal to monitor the effect of any potential perturbations on the load side, such as mass variations or cutting forces, which can lead to additional elastic deformations. In experimental results, it is shown that this compensation scheme can accurately estimate and correct for the elastic deformation, even when there is 130% variation in the translating table mass. The ED compensation strategy has resulted in 4.1 um of translational accuracy while executing at 1 m/sec feed motion with 0.5 g acceleration transients, without using a linear encoder. This result is especially significant for low-cost CNC (Computer Numerically Controlled) machine tools that have only rotary encoders on their motors. Such machines can benefit from the significant accuracy improvement provided by this compensation scheme, without the need for an additional linear encoder.

The finishing of ball screw in the market is mostly by procedures of coarse, fine and precision grinding. However, these finishing methods must undergo two processes thus they require longer time. Magnetic abrasive finishing is a fast and high precision approach, but the magnetism of magnetic abrasive is reduced when finishing ball screw, and because the centrifugal force generated tends to throw abrasive away from the processing area, the stability of finishing is thus decreased. This study mainly focuses on the effect of the magnetic gel abrasives in stainless steel pipe on the finishing efficiency of ball screw. We developed different gels as binders and restrained magnetic and hard abrasive grains in the gels to form magnetic gel abrasives. Since the gel abrasives are viscous, they can not only wrap around the abrasive grains to prevent from spreading, but also attach tightly onto the surface of ball screw. We placed the magnetic gel abrasives in stainless steel pipes to conduct finishing on ball screws, and collocated different processing parameters based on different gel viscosity to investigate the changes in surface roughness and material removal rate. The Taguchi method was applied for establishing optimal parameters for magnetic gel abrasive finishing. In order to reduce the number of experiments performed, ANSYS was used for analyzing the optimal magnetic distribution of magnetic poles, and a magnetic pole shape suitable for ball screw finishing was designed. The results showed that after 30min of ball screw finishing using aqueous slime gel with lower viscosity, the surface roughness can be decreased from 0.368μm Ra to 0.061μm Ra, and the material removal rate can be as high as 31.1mg. This proves that the magnetic gel abrasive finishing developed in this study has outstanding finishing effect on ball screws.

This research mainly develop the physical model of ballscrew positioning system and forecasts the system's response under the different operational conditions by the way of theory simulation .In addition, it uses the data which gets form the ballscrew testing machine to prove the correctness of theory simulation. Ballscrew positioning system mainly uses PID controller to drive the servo motor and the motor's turn transfers into liner motion by ballscrew. We observe the system's position response, axial force, input torque, friction torque, radial vibration, axial vibration and so on by different control parameter ,axial load and motion speed to try to find the factors which influence ballscrew positioning system. From the experiment results, we find that ballscrew positioning system's high or low axial stiffness influence the final positioning precision, especially in high load. Adding position loop's gain will make the system reach the positioning point more quickly. But vibration will increase in stop and operating. Adding speed loop's gain will make the system reach the objective speed more quickly and it can reduce the system's vibration.But higher speed loop's gain will make the system produce higher torque and vibration when accelerating and decelerating.

By their flexible production and adaptability, they are known for the inexpensive but exquisite customized products. They cooperate with satellite factories for the thorough processing system, taking the advantage of high assembly capacity and easy access to components. Among all the machine tools, grinding machine possesses the highest precision. It is expected to meet the crucial strict demands for final accuracy in the last step of manufacturing. It can be seen as the symbol of realizing the precision technology in machine tools. To promote the national hi-tech industry, Japan, Germany, America, Italy, and Switzerland all make their efforts to develop machine tool industry. However, based on the economic trends, the labor cost is increasing, the raw material price is raising, the production cost is reducing, and the production cycle is shortened. Under these pressures, production gradually has been developed with the aim to save more time, labor and also be automatic. Thus, it is a technical breakthrough for machinery development to infuse TRIZ theory into jigs designing. This is a new design mode that can adapt to the competitiveness in market. This project takes the assembly of screw on precise grinders as the research model, integrating the theory of TRIZ and researcher’s related personal experiences. It aims to refine the general jigs by the ways of design, jigs improvement, illustration of individual cases. Ultimately, after refining jigs, the further analyses about economic returns can be done. In this research, it is figured out that leading TRIZ into jigs designing possesses great potential, including gaining jigs’ common functions, realizing the high quality, reducing the cost, shortening the cycle, and enhancing competitiveness in markets. If it is used in assembly system, then it can improve assemblers and boost the diversity of products. Also, it is beneficial for production schedule and smooth distribution.

Abstract:
It is well known that preloaded ball screws with double nut produced hysteretic motion between the rotational angle of the screw shaft and linear motion of the nut, which is called “lost motion”, causes positioning error of ball screws. Preloaded ball screws with a double nut have the characteristic that the loaded balls wedge into a right angle direction to a ball rolling direction because the directions of screw shaft and nut raceways differ from the ball rolling direction. Loaded balls of preloaded ball screws with a double nut have two contact points geometrically. When the ball screw is operated under the condition of screw shaft turning and nut stationary, the wedging forces of balls are produced by differences between the screw shaft and nut raceways, and then loaded balls wedge into nut grooves. When the ball wedging motion is significantly increased, loaded balls make contact with another flank of the nut groove, that is, three points contact occur. In the present study, the authors deal with the positioning errors of the X-table which is composed of a preloaded precision ball screw and a couple of linear air bearings, and the ball wedging behaviors. The ball wedging behavior is quantified by the variation of the distance from ball surface to gap sensors which are inserted into several holes. These hole passing through the top of Gothic arch groove are bored in the perpendicular to the outer surface of the cylindrical nut.

For the accurate simulation about the heat transfer between the flowing oil coolant and ball screw structure, a heat-fluid-solid interaction transient FE (finite element) modeling method of precision ball screw unit is presented in this paper. This FE modeling method allows a supply power prediction of the oil coolant for precision ball screw unit. Then based on predictions, influencing tendencies from oil cooling strategy (oil supply temperature and volume flow rate) onto the time-varying supply powers of oil coolant are investigated. The research results demonstrate that: Firstly, the supply power of oil coolant has the increasing tendency with the time increase. Besides, the steady scale of oil supply power is in proportion to the oil supply volume flow rate, and in inverse proportion to the oil supply temperature. Finally, the maximum steady supply cooling power brings the guidance for the capacity selection of recirculation cooler for the precision ball screw unit.

Abstract:
Abstract Machine tools are required to realize high precision and high efficiency machining by various industry sectors. A machine tool has some driving systems to position cutting tools and workpieces, and hence driving units are required high speed and precision positioning. However, high speed feed motion causes thermal deformation due to generated heat at friction surfaces such as guideway, feed screw, and bearings, it deteriorates positioning accuracy of driving units. Thermal deformation of a ball screw is one of large error factors of lower positioning accuracy, and a cooling system for reducing thermal deformation is installed into machine tools. Since the cooling system needs additional cost and space in machining systems, a new method for minimizing thermal deformation is required. In this study, a new structure of ball screw is proposed in order to meet these requirements. A new ball screw which has a core pipe made of CFRP was developed. CFRP is one of composite materials which have light weight and low thermal expansion. This paper presents analysis results of a simplified FEM model of the ball screw and the basic experimental results of the developed ball screw. These results confirmed that the proposed ball screw was applied to high performance positioning system in machine tools.

Abstract:
The ball screw system is one of the most critical components in advanced manufacturing and is expected to perform with high accuracy. However, any potential failures or degradation of mechanical parts in the system would affect its efficiency and position precision; even cause severe machining errors or breakdown. This paper mainly focuses on the fault diagnosis of ball screw system components. In order to classify multiple failure modes, one full size ball screw testing machine is set up to replicate different health conditions including four failure modes — lubrication starvation, preload loss, ball nut wear, and re-circulation system failure. In this paper, the first two failure modes are introduced. Time domain and frequency domain features have been extracted from the vibration and temperature signals. A classification modeling method is used to establish a ball screw system health map. The direction of the threads on the screw shaft causes different vibration patterns when ball nut travels forward and backward. Thus, failure signatures from both traveling directions are investigated in the paper. Based on the developed health map for the ball-screw, the health values can be calculated to quantify the failure severity. Furthermore, from the perspectives of accuracy and online application efficiency, three health assessment methods, Self-Organizing Map - Minimum Quantization Error (SOM-MQE), Mahalanobis distance (MD) and Gaussian Mixture Model (GMM) are compared in the study.

Abstract:
Most machine tools rely on precision ball screw drives to accurately position the workpiece relative to the tool. In terms of the performance of such machines, tracking is one of the most important aspects that significantly affects the machining outcomes. Minimizing tracking errors of a flexible ball screw drive in the presence of runout phenomenon is explained in this paper. To achieve small tracking errors, the flexibility and runout are modeled by a linear parameter varying system. Based on the derived model, gain scheduling tracking controllers with parameter-dependent Lyapunov functions are designed. The efficiency of the designed controllers in minimizing the tracking error, as well as the importance of the runout modeling, is demonstrated on a ball screw drive experimental setup.
