“…Between the dynamic loads that affect the MT backlash, dynamic forces and thermo-mechanical loads can be highlighted: Backlash: Backlash error is a position dependant error affecting the contouring accuracy. When the axis changes direction from one side to the other, there is a lag before the table starts moving again, that would cause position error- backlash error [ 110 ]. Modelling it is challenging, due to multiple sources and complex behaviour.…”

Nowadays, errors during the manufacturing process of high value components are not acceptable in driving industries such as energy and transportation. Sectors such as aerospace, automotive, shipbuilding, nuclear power, large science facilities or wind power need complex and accurate components that demand close measurements and fast feedback into their manufacturing processes. New measuring technologies are already available in machine tools, including integrated touch probes and fast interface capabilities. They provide the possibility to measure the workpiece in-machine during or after its manufacture, maintaining the original setup of the workpiece and avoiding the manufacturing process from being interrupted to transport the workpiece to a measuring position. However, the traceability of the measurement process on a machine tool is not ensured yet and measurement data is still not fully reliable enough for process control or product validation. The scientific objective is to determine the uncertainty on a machine tool measurement and, therefore, convert it into a machine integrated traceable measuring process. For that purpose, an error budget should consider error sources such as the machine tools, components under measurement and the interactions between both of them. This paper reviews all those uncertainty sources, being mainly focused on those related to the machine tool, either on the process of geometric error assessment of the machine or on the technology employed to probe the measurand.

“…When the is groove cut with a vortex method, the dimension D and its circumferential accuracy have special meanings, both technological and functional considerations. Therefore, for the development of an efficient process, cutting a groove with a vortex method and the full use of the technological capabilities of the method, the derivation of the mathematical model of the groove diameter and its analysis are of paramount importance [22][23][24]. Figure 3 shows a diagram of the formation of the diameter of the inner circumference of the groove.…”

“…The basis for the effective organization of any technological operation is the development and management of the theoretical basis for ensuring the quality of processing and productivity [21,22]. The features of the kinematic communications between the elements of the technological system play an important role, to ensure them [3,[22][23][24][25]. Therefore, the study of the theoretical basis of the formation of accuracy when cutting a groove vortex method is an urgent task.…”

An analysis is made of the technology of vortex cutting method of groove for sealing rings provided on the lateral surfaces of rotation of a part of the sealing system and the dimensional chains thus formed, as well as accuracy issues by applying probability theories and dimensional chains. Features of the developed technology are presented; the factors influencing the accuracy of the circular diameter of the groove are analyzed, and mathematical dependencies are given for their determination; the mathematical model of the accuracy of the diameter of the groove is derived. The technological dimension chain, which is formed in the vortex cutting method of groove, is given its properties, and the new linear-circular dimensional chain, which is not found in the literature, and its mechanism of formation are presented. The features of the linear-circular dimensional chain and the management of the functional relation between the linear and circular feeds are used to determine the technological capabilities of the vortex method on the lateral surface of the groove. Also, families of possible singleand double-symmetrical forms of the grooves are identified. It is recommended to use the results obtained, when analyzing the technology of cutting of grooving and other similar surfaces with a vortex method, when solving accuracy problems, including the derivation of a mathematical model of accuracy.

Errors during manufacture of high value components are not acceptable nowadays in driving industries such as energy and transportation. Sectors such as aerospace, automotive, shipbuilding, nuclear power, large science facilities or wind power manufacture complex and accurate components that demand close measurements and fast feedback into manufacturing processes. New measuring technologies are already available in machine tools, including integrated touch probes and fast interface capabilities. They shall provide the possibility to measure the workpiece during or after the manufacturing process, maintaining the original setup of the workpiece and avoiding the manufacturing process from being interrupted to transport the workpiece to a measuring position. However, the traceability of the measurement process on a machine tool is not ensured yet and measurement data is still not fully reliable for process control or product validation. Due to the similarity between a coordinate measuring machine and a machine tool, some of the methods applied for a correct assessment of uncertainty in coordinate measuring machines are adapted to the challenges of a machine tool. The scientific objective is to determine the uncertainty on a machine tool measurement and, in this way, convert it into a machine integrated traceable measuring process. This paper reviews the fundamentals of machine tool metrology.
