The blank is the most initial state of a part,but Parts are formed by the blank according to various technical requirements after a variety of processing.The blank choice is not only affects the blank manufacturing technology and the cost of enterprise, but also has close relationship with the machining technology and quality of parts.Therefore, it needs the close cooperation of technicians in both the manufacturing and mechanical processing to reasonably determine the blank material, structural shape and size .
Ⅰ. Requirements to be met in material selection
Mechanical products are composed of a number of parts, ensure the use of parts is to ensure the use of the product requirements.Therefore, the blank selection must first meet the parts performance requirements.
1) Structural shape and size requirements
Due to the different functions of mechanical parts, their structural shapes and sizes are often very different, and various blank manufacturing methods have different adaptability to the structural shapes and sizes of parts.Therefore, when selecting the blank, the structural shape and size characteristics of the parts should be carefully analyzed.Select suitable blank manufacturing method.
