“…The dynamic properties of the machine tool are reduced to the properties of the spindle with the three-jaw chuck, and the experimental extended inverse receptance coupling (EIRC) method, described in detail in [ 23 ]. This method allows one to take into account the rotational degrees of freedom (RDOF) of the system, necessary to properly model the way the workpiece is clamped in the three-jaw chuck.…”

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.

“…Researchers proposed such active and passive dampers or appropriate selection of technological parameters of machining to reduce vibration in machine tools. [6][7][8][9][10][11][12] Further, the system dynamics may vary with different machining processes, and a wide range of dampers need to be developed and used for different requirements. Hence, the above methods are not versatile, and their utilization is limited to a certain predominant frequency [13][14][15][16] range.…”

Machine tool structures are subjected to continuous distortions and unwanted vibrations during machining. The structures should have excellent static and dynamic properties to minimize the adverse effects due to vibration. Cast iron is generally used as a structural material for machine tools owing to its higher structural rigidity and moderate damping properties. The lack of desired dynamic properties results in poor surface finish of the machined components. Epoxy granite is a resin mineral-based composite found to provide superior damping ability but it has lesser material stiffness. Steel reinforcements are more appropriate to enhance the static rigidity of epoxy granite structures. The cast iron spindle head of the vertical machining center is considered for the present study. Static structural analysis has been performed by finite element analysis and the results are considered as a benchmark for the design of epoxy granite spindle head. Multiple design configurations of steel reinforcements are evolved through topology optimization to achieve improved stiffness with a higher damping ratio. A model which exhibited higher stiffness with minimum steel has been proposed for fabrication. A 1:2 scaled model of the proposed configuration has been fabricated using epoxy granite. Experimental modal analysis and numerical static analyses have been carried out and the results are compared to those of cast iron spindle head. A significant reduction in mass and deformation of the epoxy granite spindle head by 22% and 57%, respectively, was observed compared to that of cast iron spindle head.

“…The complexity of solutions used in CNC machine tools is still growing new methods of surface quality improvement [ 1 ] and topographic inspection [ 2 ], and continuous miniaturization that require an accuracy range in micrometers [ 3 ]. Machining tools are also constantly being developed and extended with modern, complex systems, such as compensation of thermal errors of a ball-screw-driven [ 4 ] or cutting stability [ 5 , 6 ]. In addition, more advanced solutions have been proposed by Gomez-Acedo et al [ 7 ].…”

The human-machine interfaces in modern CNC machine tools are not very intuitive and still based on archaic input systems, i.e., switches, handwheels, and buttons. This type of solution has two major drawbacks. The pushed button activates the movement only in one direction and is insensitive to the amount of the force exerted by the operator, which makes it difficult to move the machine axes at variable speeds. The paper proposes a novel and intuitive system of manual programming of a CNC machine tool based on a control lever with strain-gauge sensors. The presented idea of manual programming is aimed at eliminating the need to create a machining program and at making it possible to move the machine intuitively, eliminating mistakes in selecting directions and speeds. The article describes the concept of the system and the principle of operation of the control levers with force sensors. The final part of the work presents the experimental validation of the proposed system and a functionality comparison with the traditional CNC control.
