First, the type and content of the graphics database Function library In the development process of this system, according to the technical standards and special requirements of the tool, a variety of calculation methods are collected, compiled and developed, such as the calculation method of the blade groove coordinates, the calculation method of the machining spiral groove milling cutter, etc. The method is compiled into a general subroutine, which forms a function library, which can be called at any time in the design and is very convenient to use. The contents of the function library can be continuously expanded and improved during use. 2. Graphics library According to different data structure forms, the graphics library is divided into the following two types: (1) 3D graphics library The purpose of establishing a 3D graphics library is to facilitate direct calling in the design; the second is to facilitate modification or modification on the basis of the original product, to develop a new product series and to carry out non-standard design. The following sub-libraries are included in the 3D graphics library: 1 Graphic construction tool library Carbide indexable tool has complex structure, large number of parameters and sizes, large shape change, and typical structure of local structure, such as spiral groove, insert groove, water inlet and outlet. Traditional design methods are often based on empirical qualitative design, and the rationality and accuracy of the design are difficult to grasp. In the development of this system, in order to improve the design quality and shorten the design cycle, a tool library based on Catalog-Feature and Catalog-Section in IDEAS DESIGN application module was developed to store the features and sections as the construction tool in the design process. . Such as the construction of inner and outer blade slots, water holes, feature blocks and sections of spiral grooves. 2 Standard Parts Library In the tool design, many parts have the same structural shape, but different size specifications, such as standard handles, screws, blades, etc. After sorting and sorting these serializable parts, use the Catalog function in IDEAS software to solidify all series of parts. When using, you can directly click the corresponding series in Catalog-Part, when the required graphic is displayed on the screen. It can be rotated, moved, enlarged, reduced, modified and various editing operations, which is convenient and flexible to use. It can be called at any time in the design. 3 Non-standard parts library Use the Library in IDEAS software to store non-standard parts obtained through design or standard parts modification. It can be called directly when it is used, or it can be modified after use. 4 Tool finished product library The designed tools are stored in categories to form a finished tool library. The contents of the library can be retrieved, called, or edited at any time. When the design structure is basically the same, only when the tool is slightly changed locally, it is not necessary to start designing from the parts. It is only necessary to directly call out the similar finished product, and the partial modification can complete the design. Next page The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow. 75 cm cell culture flask,t75 cell culture flask,suspension cell culture flask Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yonyuetip.nl
Based on the trend of product demand and the requirements of developing new products, our factory has developed a CAD/CAM system (CCTCADAMS) for carbide indexing tools for some typical types of cemented carbide tools. The system adopts the advanced design technology of automation and interactive design organic integration, makes full use of human-machine resources, has a preliminary level of intelligence, can better complete the variable parameter design and adaptive design of the tool, and can utilize the interactive design method. The auxiliary designer completes the development design of the special tool and uses the CAM technology to generate the CNC machine tool instruction code. In the CCTCADAMS system, the graphical database management system is used as a separate design module for storing and managing the necessary and generated parameters and 2D and 3D graphics in the tool design. It is fundamental and critical in the whole system. Subsystem.
