“…Despite much effort having been made to automate the calculation of geometric dimensioning and tolerancing (GD&T) in the way of dimension chains, researchers have not proposed comprehensive solutions so far. Thus, further development of dimension and tolerance analysis is needed to complete dimension chains automation by using more appropriate theoretical models [73,75].…”

The concept of smart manufacturing has become an important issue in the manufacturing industry since the start of the twenty-first century in terms of time and production cost. In addition to high production quality, a quick response could determine the success or failure of many companies and factories. One the most effective concepts for achieving a smart manufacturing industry is the use of computer-aided process planning (CAPP) techniques. Computer-aided process planning refers to key technology that connects the computer-aided design (CAD) and the computer-aided manufacturing (CAM) processes. Researchers have used many approaches as an interface between CAD and CAPP systems. In this field of research, a lot of effort has been spent to take CAPP systems to the next level in the form of automatic computer-aided process planning (ACAPP). This is to provide complete information about the product, in a way that is automated, fast, and accurate. Moreover, automatic feature recognition (AFR) techniques are considered one of the most important tasks to create an ACAPP system. This article presents a comprehensive survey about two main aspects: the degree of automation in each required input and expected output of computer-aided process planning systems as well as the benefits and the limitations of the different automatic feature recognition techniques. The aim is to demonstrate the missing aspects in smart ACAPP generation, the limitations of current systems in recognising new features, and justifying the process of selection.

“…В процессе подготовки производства важно проектирование каждой технологической операции для обеспечения оптимальной степени точности установочной партии деталей. Проектирование содержания технологических процессов выполняется по рекомендациям производителей основного оборудования, станочной оснастки и инструмента, справочных данных, основанных на исследованиях точности технологического оборудования, анализа межоперационных размеров [8,9] как по линейным [10], так и по диаметральным и радиальным параметрам [11] или эксцентриситетам [12]. Перечисленные технологические методы хотя и позволяют задать значения показателей процессов обработки резанием, но не учитывают фактическое состояние технологического оборудования, оснастки и инструмента.…”

An example of the application of the experimental planning method in the APQP pre-production process to find the values of the cutting process parameters that provide a given margin of accuracy is considered on the example of roughing and finishing boring of the inner hole of the camshaft bearing housing. From the total set of geometric parameters, special characteristics are highlighted - the size of the inner hole, which ensures the fit tolerance of the steel-fiber sleeve and the height parameter of roughness Ra, as well as radial runout. The objectives and results of the application of engineering methods (calculation of allowances, dimensional analysis, evaluation of technological accuracy of machine systems, planning experiments) as well as special methods of APQP process (quality management tools - FMEA analysis, SPS, MSA) are considered. Attention is drawn to the insufficient information content of the methods, which does not allow for the selection of process indicators to ensure the necessary margin of accuracy of special characteristics. In order to achieve a given margin of accuracy, technological components of the internal diametrical size are identified - the deviation of the tuning size, the deviation of the cross-section profile and the height roughness parameter Ra, the values of which are found as a result of production experiments. The planning of a full-factor experiment is carried out according to the parameters of the cutting process - cutting speed, feed and cutting depth. To implement the plan, special samples of products with a stepped allowance were designed and manufactured. The shape of the product samples makes it possible to reduce the number of samples for a full-factor experiment from eight to four, providing a check of the linearity of regression models. The calculation and regression models are given, which allow predicting the values of the components of the internal diametrical size at the design stage of the manufacturing operations of parts. The solution of the regression model system that satisfies the specified limitations for a given margin of accuracy allows you to find the optimal range of values of the parameters of the cutting process, to provide rare settings of special characteristics in the serial manufacturing process of camshaft bearing housings. Systematic application of the methodology, along with statistical methods of quality management, allows monitoring the technical condition of equipment and maintaining it in the condition required for the production of quality products.
