The calculation of the lifespan of profile rail guides is an essential part in the design process of machines. Conventional lifespan models yield good results when calculating lifespan values under a homogeneous distribution of individual rolling contact forces on the raceways. In the case of an uneven load distribution, significantly too low lifespan values are calculated, resulting in a considerable loss of lifetime potential. The novel and experimentally validated rolling contact-based lifespan calculation (RCBL) takes the transferred force on each rolling element into account, resulting in more realistic lifespan values that can be up to 4 times higher than those obtained through the classical method. The disadvantage lies in the complex calculation of the necessary individual rolling contact forces, which until now has been done by using extensive finite element models, along with the computationally intensive optimization problem of the RCBL. To overcome these disadvantages, a method is introduced that efficiently calculates the individual rolling contact forces, taking into account all relevant system elasticities, and pre-solves the RCBL for a variety of potential superimposed load combinations. The results are subsequently approximated through an analytical multiparametric polynomial function and can be utilized with the conventional lifespan formula for rolling bearings.

Bioprinting is a process that uses 3D printing techniques to combine cells, growth factors, and biomaterials to create biomedical components, often with the aim of imitating natural tissue characteristics. Typically, 3D bioprinting adopts a layer-by-layer method, using materials known as bio-inks to build structures resembling tissues. This study introduces an open-loop control system designed to improve the accuracy of extrusion-based bioprinting techniques, which is composed of a specific experimental setup and a series of algorithms and models. Firstly, a method employing Logistic Regression is used to select the tests that will serve to train and test the following model. Then, using a Machine Learning Algorithm, a model that allows the optimization of printing parameters and enables process control through an open-loop system was developed. Through rigorous experimentation and validation, it is shown that the model exhibits a high degree of accuracy in independent tests. Thus, the control system offers predictability and adaptability capabilities to ensure the consistent production of high-quality bioprinted structures. Experimental results confirm the efficacy of this machine learning model and the open-loop control system in achieving optimal bioprinting outcomes.

When complex and thin-walled workpieces produced for the aircraft industry are machined, they are supported by fixtures to prevent them from easily deforming or vibrating. To support the workpieces effectively, the stiffness of the fixture should be sufficiently high. However, the criteria required for the fixture dynamics to effectively support a workpiece during machining have not been thoroughly investigated. To minimize trial and error, the design parameters required for the fixture should be determined theoretically. Accordingly, this study proposes a method for theoretically determining the design parameters of a fixturing system. The effect of the substructure thickness on the dynamics of the entire structure was evaluated quantitatively using a theoretical model, and the validity of the model was verified experimentally. The stiffness of the entire fixturing system was estimated using the reacceptance coupling method. In addition, the relationship between the thickness of the substructure and stiffness of the entire structure was evaluated.

The hardening-finishing treatment of parts surface with rolling by steel cylindrical rollers produces low roughness, reduced residual compression stresses, and fine-grained structure due to plastic deformations. The deformation of metals during machining at high temperatures is characterized by a significant influence of strain rates on stresses. This necessitates the calculation of stresses and strains based on the equation of state of rheonic bodies. This study aims to determine the components of stresses and force factors of the technological process of finishing and strengthening machining of the surface of parts by deriving the analytical solutions to calculate the stress-strain state within the deformation zone based on creep theory. In this problem, general formulas are obtained for calculating the stress-strain state, pressure and friction forces on the contact surface, as well as forces and moments acting on the roller. Numerical analysis using Mathcad explores the understanding of the stress-strain state in the deformation zone on the force factors of the technological process. The obtained results are beneficial for establishing the mode of thermomechanical processing and selecting appropriate technological equipment for restoring flat surface parts.

Deep drawing processes play a pivotal role in the manufacturing of sheet and shell products, making it a widely adopted method. This research employs numerical simulations to investigate the impact of various process parameters on the fracture height of cylindrical cups made from SECC (Steel Electrogalvanized Commercial Cold rolled) material. Specifically, it examines parameters such as blank holder force (BHF), punch corner radius (Rp), die corner radius (Rd), and punch-die clearance (Wc). The study extends to optimizing fracture height, offering a solution to this challenge. Subsequently, the selected parameters are validated through experimental deep drawing of cylindrical cups, resulting in a minimal deviation of 1.55% between simulation and experiment outcomes. A precise mathematical equation is developed to estimate fracture height under diverse machining conditions, with a maximum deviation of 4.52% observed between the mathematical model and simulation. These findings represent a substantial advancement in deep drawing processes technology, particularly in reducing error rates during the production of cylindrical cups .

These days, most machine tools are interlocked by an enclosure for safety control. At that time, internal heat generation in machine tools first causes thermal deformation of the machine structure, which reduces the machining accuracy of the workpiece. Furthermore, the internal heat generation heats the air inside the enclosure, causing a heat build-up phenomenon, and the trapped heat causes re-thermal deformation of the machine tool structure. As a result, machine tools with enclosures are subject to extremely complex thermal deformation. On the other hand, we would like to use FEM thermal simulation to study thermal deformation countermeasures for machine tools with enclosures at the design stage, but it is difficult to analyse the heat build-up phenomenon using conventional FEM thermal simulation. In this research, the new FEM thermal simulation technology for the heat build-up phenomenon was developed and heat build-up phenomenon in a CNC lathe with enclosure was calculated using the proposed FEM simulation technology. As a result, it had been concluded that the proposed FEM simulation could calculate with high accuracy for the phenomenon of heat build-up in a CNC lathe with enclosure, and the proposed technology is very effective in the design.

In wet cutting, lubricants are used to improve lubrication, forced cooling and chip evacuation. In particular, improving the lubrication between the tool and the chip results in a lower coefficient of friction, suppressing the tool temperature change and improving the cutting properties. For this reason, tools coated with DLC (Diamond Like Carbon) or diamond have been developed to further reduce the coefficient of friction. However, the tool life is still not sufficiently long. Therefore, in this study, a cutting fluid for polishing tools during cutting was developed and evaluated. First, using the author's previous research, the function, effect and influence of several cutting fluids on milling were identified. Secondly, a new criterion for determining tool life was defined and, based on this criterion, a cutting fluid was proposed to polish the tool during the cutting process. Next, the machining conditions under which the proposed cutting fluid would be effective were identified. Finally, the cutting properties of the proposed cutting fluid were evaluated. The results showed that (1) the cutting fluid was developed to polish the tool during the cutting process and the optimum machining conditions were clarified, (2) the proposed cutting fluid was very effective in increasing the tool life.

Thermal errors are one of the leading causes for positioning inaccuracies in modern machine tools. These errors are caused by various internal and external heat sources and sinks, which shape the machine tool’s temperature field and thus its deformation. Model based thermal error prediction and compensation is one way to reduce these inaccuracies. A new composite correlative model for the compensation of both internal and external thermal effects is presented. The composite model comprises a submodel for slow long-and medium-term ambient changes, one for short-term ambient changes and one for all internal thermal influences. A number of model assumptions are made to allow for this separation of thermal effects. The model was trained using a large number of FE simulations and validated online in a five-axis machine tool with measurements in a climate chamber. Despite the limitations, the compensation model achieved good predictions of the thermal error for both normal ambient conditions (21°C) and extreme ambient conditions (35°C).
