“…Based on current research, it was found that the main tool for improving the quality of mechanical industry products, reducing the time-frame in the product development cycle, as well as the simultaneous introduction of accuracy and manufacturing stability and, of course, minimum production costs, is the improvement of production design engineering through the development of a process planning system. Indeed, according to the research by scientists in this field [1][2][3][4][5][6][7], it was determined that process planning is a priority objective for product design engineering, which is almost half its labor intensity.…”

Technological assurance and improvement of the economic efficiency of production are the first-priority issues for the modern manufacturing engineering area. It is possible to achieve a higher value of economic efficiency in multiproduct manufacturing by multicriteria optimization. A set of optimality criteria based on technological and economic indicators was defined with the aim of selecting the optimal manufacturing process. Competitive variants and a system of optimization were developed and investigated. A comparative analysis of the optimality criteria and their influence on the choice of optimal machining processes was carried out. It was determined that the batch of parts made an impact on the selection of the manufacturing process.

“…Because a collet chuck is basically a wedge mechanism, the static clamping force for a given acting force to the mechanism depends on the friction coefficients of the tapered and clamping surfaces, on clearance between the collet and the clamped part, and on collet stiffness [12][13][14][15][16][17].…”

Automatic Expanding Mandrel with Air Sensing Device: Design and Analysis

et al. 2020

In precision machining, expanding mandrels are used for jobs with close tolerances. An expanding mandrel consists of a tapered arbor or shaft, with a thin-slotted clamping sleeve or collet made of hardened steel. The internal tapered and external cylindrical surfaces are ground to a high degree of accuracy, and the mandrel expands to fit the internal bore of the workpiece. Expanding mandrels are, essentially, wedge mechanisms. This paper proposes an automatic expanding mandrel with a novel force transmission system for high stiffness within a novel air sensing system, which allows detection of the correct part position before starting machining. A computational model for determining the dynamic clamping force of the proposed mechanism is developed and implemented using MATLAB. This model considers the influence of the stiffness behaviors of the collet, force transmission structure and workpiece. Additionally, this paper presents the finite element method analyses which were conducted to check the proposed computational model. The amount of clamping force transmitted by a collet chuck holder depends strongly on: clearances, wedge angle, stiffness of the collet chuck holder and workpiece stiffness.

“…One of the perspective directions for the implementation of scientifically grounded design method is the design of body parts of metal-cutting machine tools. Nowadays, during designing of body parts of metal-cutting machine tools mainly used calculation schemes [1] in which the real designs of metal-cutting machine tools are presented in the form of simple beam and plate models, as well as general empirical recommendations obtained on the basis of experimental studies of existing body parts. Such kind of approach does not allow to sufficiently substantiate the feasibility of the application of a particular body component design and significantly complicates the assessment of new structures of body parts, in which there is no experimental data.…”

This paper describes a developed new method of body parts force displacements calculation of metal-cutting machine tools using combination of CAD and CAE technologies. It was carried out the analysis of analytical methods and the method of finite elements of body parts force displacements calculation of metal-cutting machine tools. On the basis of it the requirements to the method of calculation of compound errors of processing and deviations of the form of the processed surfaces due to deformations of the body parts of metal-cutting machines are established. The method of designing metal-cutting machines is grounded, which is based on mathematical modeling of different processes. It gives an opportunity to evaluate the accuracy of the machine and the impact on it of the individual assembly already in the initial stages of designing. The calculation methodology was implemented using ANSYS finite element analysis. This technique was used in the calculations on the example of high-precision lathes.
