“…Simultaneously, the effectiveness of computer-aided design (CAD) systems and the quality of decisions depend on built-in principles, methods, rules and algorithms for converting existing technical and technological knowledge [15,37,39,41] into specific technological process for parts manufacturing. Therefore, technologies designed in a CAPP must have the reliability of ensuring a given dimensional accuracy [16] and the requirements for the cross-referenced tolerances (orientation and location of surfaces) [5,6,9,39], which can be characterized by an accuracy margin indicator [5,15,16], defined as the ratio of given error of an accuracy parameter to its error expected during the TP implementation.…”

“…The technical quality of products is established and ensured at product life-cycle (PLC) stages like marketing research, product design, technology development and product manufacturing. Moreover, the technological support of parts quality indicators already begins at the design stage [2][3][4][5][6].…”

“…Accordingly, the role and importance of a 3D model of an operational workpiece in the manufacturing process planning and organization is increasing, which is possible if these processes are automated. It can be concluded that during the technological process planning, the entire set of interconnected operational workpieces (their 3D models) should be developed in an automated (automatic) mode [35,36], taking into account the assurance of the part accuracy parameters without defects [4][5][6]37]. To accomplish the latter, it is necessary to minimize or eliminate the influence of the subjective factor by creating knowledge, rules and techniques bases [4-6, 16, 38-40].…”

The paper considers the problem of accuracy assurance during part manufacturing. Ensuring the required accuracy is one of the aspects of achieving the level of quality, implied during product design. It should start even before the actual manufacturing process, during process planning, which is one of the main stages in product life-cycle. In digital manufacturing, while using automatic and semi-automatic equipment, including CNC machines, a multi-operational technological process must be reliable in the context of ensuring its accuracy parameters, i.e. must guarantee in advance the compliance with requirements of dimensional accuracy and surfaces location and orientation which is specified in a part drawing. This can be achieved by carrying out a dimensional accuracy analysis of a technological process at its design stage, which will reduce time and material costs when introduced in production, due to a significant decrease in the probability of obtaining defects, related to precision parameters. When conducting a dimensional accuracy analysis of a technological process, it is necessary to preliminarily create diagrams of linear dimensions and circular runouts. Creating these diagrams and performing the required calculations manually is a rather time-consuming process. This fact as well as the lack of necessary software packages (even though there exist several programs for calculating linear and diametric dimensions and machining allowances, developed by authors of the present paper) today at industrial enterprises engineers do not conduct dimensional accuracy analysis when designing multi-operational manufacturing processes and rely solely on their own experience and the experience of adjusters and CNC machine operators. And this, in turn, holds back the process of manufacturing process automation, which is unacceptable during the transition to digital manufacturing. As a solution to this problem, it is proposed to introduce into the practice of technological process design developed calculation programs and a software tool in development, based on methods of interactive synthesis of linear dimensional and runout diagrams, described in the paper.

In the presented article, the issue of the implementation of magnetic abrasive processing is considered in order to ensure the quality of surfaces of complex shapes of parts made of corrosion-resistant aluminum alloys. The implementation was carried out through theoretical and experimental research. In a theoretical study, the features of processing corrosion-resistant aluminum alloys, existing and possible schemes for magnetic-abrasive processing of surfaces of complex geometric shapes, including a combination of various working movements of the workpiece and pole pieces, are considered. In an experimental study, the dependence of the quality of the processed surface (roughness) on the size of the working gap between the workpiece and the working pole was determined. The result of the research is the determination of the optimal treatment schemes for surfaces with a complex geometric shape, as well as the derived exponential dependence of the change in surface roughness on the size of the working gap.
