Design for manufacturability in virtual environment using knowledge engineering

Abstract

Design for manufacturing (DFM) strategies help companies to develop new products that are feasible to manufacture. In the early stages of design all engineering activities are initiated in computer aided systems. When the design is finished, the process of manufacturing and production planning begins. Issues often occur at this point because two teams, designers and manufacturers, have been working separately. The resulting question is: ‘how can Knowledge Engineering (KE) be used effectively to enhance manufacturability during early design?’ Even if the most complex geometrical product can be realized using today’s technologies such as rapid prototyping it is only true in unit production. In lot and mass production where CNC machines are used, complex geometry causes a number of difficulties. So it is important to investigate the project carefully in the early design stage from the point of view of whether it will be possible to manufacture.

Development of Electric Drive on the Basis of Five-Phase Synchronous Electric Motor

“…To study the control principles and the development of power boards, a mock-up engine was created (Figure 8). The mock-up of the engine has been created with CA support to enable the use of CAD, CAM, DFM, and other systems that help achieve higher product accuracies and help companies develop new products [23][24][25]. To study the principles of control and the development of power boards, a mocku of the motor was developed (Figure 8).…”

The stator is assembled from individual coils in 5 groups, each group is connected one of the power supply phases, the phases are connected in a "star" pattern (Figure 9) The stator is assembled from individual coils in 5 groups, each group is connected to one of the power supply phases, the phases are connected in a "star" pattern (Figure 9).…”

Методы И Модели Поддержки Принятия Решений При Управлении Инновационными Проектами В Производственно-Экономических Системах

“…Следовательно, необходимо прогнозировать возможные негативные последствия принятых решений из-за неадекватной оценки проблемной ситуации, связанной с недостаточным опытом ЛПР или его некомпетентностью. Вопросы повторного использования знаний применительно к производственным сетям малых и средних предприятий рассматривались в [38], вопросы принятия решений при управлении взаимодействующими процессами в проектно-ориентированных организациях освещались в [39][40][41]. В развитие этих подходов авторы предлагают классифицировать проблемные ситуации и принятые решения в соответствии с областями знаний и уровнем ЛПР в организационной структуре управления проектом.…”

Simulation Modeling of Innovative Project Management Processes

“…A process of describing a complex dynamic system conceptual model is itself time-consuming and complex [7]. Methods of subject area abstracting and formalization help to reduce the complexity of the innovative project modeling process.…”
