Design Of Computer-aided Cotton Spinning

This system is based on the arranging principle of the cotton-spinning mill. Running the system, we can realize the parameter and automatization of the drawing of the cotton-spinning mill. When we enter the necessary parameters, the drawing of machines of every workshop will be showed automatically in AutoCAD screen.The drawings by hand have many disadvantages. First, the precision is low. Second, we cannot use it repeatedly. Otherwise, it wastes a great deal of time and energy. Adopting the computer aided design, we can greatly increase efficiency. It can save time and energy and get over the shortcomings of the drawing by hand. When we draw a map in the AutoCAD screen, it cannot completely realize the parameter and automatization of the drawing. Many labors are still wasted. Finishing an item will take much time. In the competing market economy, it cannot fit the social development.In order to show the drawing of the cotton-spinning mill in AutoCAD screen we make use of Visual Basic to control AutoCAD. When you enter necessary parameter in the form, the drawing of cotton-spinning workshop will be automatically showed. This system achieves the parameter and automation of drawing in deed.Because the number of the roving machines must be even between two poles and another kinds of machines have not special demands, the distance between the two side poles, two main poles and two middle poles have to be decided by the roving machines. The numbers of distance between the poles in the left and right have to be decided by the number of machines of the spinning machines. Since this, all workshops in the spinning will use the same values of distance between the two side poles, the two main poles and the two middle poles. Then according to the arranging principle of each workshop we write program in Visual Basic. In the end we realize our demand.In the text, we briefly introduce some context above all. First, the concept and development of the computer-aided design are introduced. Second, some applications of CAD are referred to the textile. Third, the design of cotton-spinning mill and how to apply the computer in the design are recommended.Then we particularly set forth the arranging principles of every workshop, the operation methods and the principles of programs in the spinning, such as the spinning workshop, the roving workshop, the combing and so on. The drawing of machines and dimensions will be clearly showed in AutoCAD screen when you run the system. If user has special demands, he can conveniently modify and compile the drawing in AutoCAD screen. In the other hand, user can also independently draw a workshop in this system so that much repeated labor can be saved.Users should run the system according to the operation step and cue of program. This system has perfect function, reasonable structure, simple process and clear form, user can be familiar and apply it soon.
