Efficient Sawing Machining Algorithm For Complex Curved Surface With Different Type Stone

As one of the important construction industries,the stone industry is developing rapidly with the devolopment of the economy,culture,and materials.With the continuous increase in people's demand for material quality in life,the demands for stone and the mining volume are increasing.The stone processing industry,is also booming.The stone processing industry is the main output model of stone products,its processing efficiency and processing quality determine the standard of stone processing industry.Stone relief is a typical complex type of products.In traditional processing,diamond milling cutter is used for rough processing and finishing to complete the entire processing process.However,milling cutter processing efficiency is low,and removing a large amount of margin in rough processing is a long time.Therefore,this paper proposes the use of diamond circular saw blade instead of traditional milling cutter to cut rough processing,reduce the processing cost,the work done mainly includes:l.In this thesis,the material removal mechanism of sawing stone is studied,and the surface quality of stone,cutting force of stone,and vibration characterstics are investigated.The influence mechanism of parameters in saw cutting process is obtained.The processability of different kinds of stone is analyzed,and the relevant conclusions are given according to the parameter selection of saw blade processing.The influence of different parameters on the quality of saw cutting is investigated.The failure forms of saw blade under different parameters are analyzed and the influencing factors of saw blade life are obtained.2.The model of saw cutting process is established,and a series of interference points are obtained by checking the surface surface in saw cutting process,and an algorithm for excluding interference points is proposed based on the dilemma method.A surface model is built in MATLAB software.The interference point distribution is obtained by simulation,and the feasibility of the algorithm is verified.3.The general method of tool path planning is obtained during the analysis of embossed milling process.Based on this method,a tool walking method and a path planning method in the process of circular saw blade processing are constructed using the knife contact path cross section line method.In curve processing and curved surface processing,the method of calculating the cutting path is given,and an effective and feasible tool path is obtained.The efficiency of the sawing algorithm is verified by comparison with milling machining.Through C++software,the tool path planning program can automatically generate the processing program code according to the graphical parameters.It has certain guiding significance for the promotion and development of saw cutting process.
