Research Of Three-Dimensional Stone-carving Products Efficient Machining Technology

With the advancement of urbanization in our country, demand of stone carvi ng products is growing, which puts forward higher requirements for these machi nes and technology. At present, China’s stone carving products are mainly manu fectured by hand, although there are developments in machines recently, adopted processing craft lacks of efficiency. Foreign advanced and efficient processing equipment such as engraving robot has high performance, however costs too mu ch and is difficult to automatically make programming, also demands too much for the operator, which is not suitable for the present situation of stone carving industry of our country. Therefore, to develop efficient processing equipments w hich are suited to China’s stone carving industry and to study the feasible effici ent processing technology are the inevitable choice of development.This paper will realize the simple classification of the typical stone stereo te chnology products according to the study of processing operation demands of th e stone carving products, then present the scheme that 3+N axis series of sto ne carving products processing equipment. The research contents mainly include two parts below:design of processing equipments for the stone carving produc ts and research of efficient processing crafts.We select the 2P1RB+R type 4-axis equipment whose maximum machining d imension is φ800×1000mm as the Representative to study. In the process of structural design, we will use the workbench14.5 to make a static analysis and modal analysis for the whole machine, so that guarantee the dynamic and static characteristics meet the requirements of the processing.Triangles in the STL data model structure are analyzed, and on this basis an d with the help of VISUAL STUDIO 2012 C++ machining path automatically generated problems is studied, eventually it is realized that G codes of complete tool path of circular saw, taper cutter and incomplete tool path of circular saw are automatically generated. On this basis, using Ansys and Adams conducted practical processing route of movement error analysis, in order to make equipm ent machining precision to meet the design requirements. At the same time, wit h the help of Vericut, the generated paths are checked for cut and allowance to prove the validity.In this subject, plan design of the stone carving products 3+N axis processi ng equipments was carried on, and the four axis (2P1RB+R) processing equipme nt structure design was completed, and NC code for circular saw rip-cutting pat h and cross-cutting path were automatically generated, we realized the simulatio n of them, and meanwhile error analysis of equipments for practical processing path was carried out. It is of great significance that 3+N axis series of stone carving products processing equipments were presented for improving the level of our design and standardization degree for stone carving products processing equipments, proposed and implemented analysis of the actual path based on Ans ys and Adams equipment error, has important guiding significance for research of precision of carving products processing equipments.
