Abstract:
Design decisions for a detail (the form, structure of surfaces, the sizes, accuracy, roughness and technical requirements) are accepted considering first of all functional requirements. At the same time the designer carries out the improvement of a detail on general adaptability to manufacture and makes changes to details without touching their functionality. As a result, there is developed and approved the working drawing of a detail and corresponding technical requirements concerning dimensional accuracy, accuracy of the form, accuracy of a relative positioning of surfaces, their roughness and other technical requirements.
