Research On Profiled Surface Stones Of Combined Machining Technology And Equipment

With the development of stone machining industry, the use of combined machining technology has become an important measure of improving the machining efficiency. Foreign multi-functional combined machine center is very expensive, and difficult to promotion. The research and development on multi-functional combined machine center is still blank in China. Development and promotion multi-functional combined machine centers which is fit for our own conditions and having independent intellectual property have become the key on improving quality and enhancing the competitiveness of China's stone industry. Combined machining technology on profiled surface stones has been reflected in a few specific machines, but lack of a systematic theory system, and combined machining equipment is also lacking of systematic study. As people improve the requirements to the profiled surface stones, the mechanical properties of the equipment need more stringent requirements too. The equipment with a good dynamic and static characteristic has become one of emphases and difficulties in the entire research and development.Systematic researched the machining craft on profiled surface stones. The theory of combined machining technology was divided into three categories: there are craft combination and movement combination and tool combination. Founded machining kinematics spectrum for combined machining equipment, and established a good theoretical foundation for the research and development of combined machine center of profiled surface stones. Analyzed a variety of similar equipments' principles and functions and structures, took full account of characteristics of the profiled surface stones which are sold in the market and machining craft and the customers' requirements, at last got a kind of high-efficiency combined machine center scheme that possesses of many crafts such as milling, grinding, drilling, polishing and sawing machining. Modular technology was used to plan the equipment scheme, used SolidWorks three-dimensional software to found initial three-dimensional models.Did mathematical modeling study to modal analysis theory on dynamic characteristic for the functional parts of the high-efficiency combined machine center, mastered the basic principle of mathematics. Tested modal characteristics for a similar equipment which made in foreign country, mastered some key technologies in its dynamic performance. Full used of CAD / CAE integration technology, established a number of simplified models for the functional parts of high-efficiency combined machine center in SolidWorks software, and input into ANSYS software to do simulation calculation, analyzed and compared the results, selected the design scheme which has reasonable weight, good static and dynamic performance. In order to provide effective references in modifying and optimizing the performance to the functional parts, and reduce the blindness in amending the mechanical properties, did sensitivity analysis in the static and dynamic performance to the parts, identified the biggest key component. Based on research results, improved the design scheme for the each functional part. At last, a relatively satisfied equipment structure design scheme was got. And cooperated with an enterprise to manufacture.Successful researched and developed of high-efficiency combined machine center means that China has broken the situation that stone machine center only rely on importing. The process of research and development in high-efficiency combined machine center also has a good value to the other equipments.
