Surface Topography Analysis And Process Optimization For Five-axis High-speed Milling

High speed machining and five axis machining technology has been widely applied, and becomes a hot research topic in the field of manufacturing process. In recent years, most studies focus on the planning of tool path, and the surface morphology of the five axis machining parts are less involved. In this paper, the surface morphology of the workpiece according to the characteristics of the five axis high speedmilling of qualitative and quantitative research. According to the formation mechanism of the five axis high speed cutting surface morphology, the main affecting factors and the establishment of simulation model, to explore the ways and methods to obtain specific surface topography.The main research contents of this paper are as follows:1. The research progress of five axis high-speed milling, looking on at this stage manufacturing and application situation of five axis machining requirements and needs assessment, put forward the surface morphology of five axis machining parts, explore ways to establish the mapping relationship between the five axis machining parameters and surface morphology parameters, determine the surface topography of high speed milling of five axis direction.2. In the five axis high speed milling conditions, through the three-dimensional surface topography analysis of the workpiece surface topography measurement results, combined with the image and the numerical results of Talysurf_CLI1000 in surface topography measurement, according to the definition of ISO25178 on the texture and surface roughness characteristics, re description of morphology of the five axis high speed milling surface.3. Formation mechanism of surface morphology of five axis free-form surface machining. Analysis and comparison of structure characteristics and ball-end tool and filleted-end tool nasal process, 3D surface topography simulation model of the blade sweep built five axis high speed milling condition, and through the orthogonal experiment to verify the milling depth is the most important factor, followed by milling width.4. Research on Application of filleted-end tool in five axis free-form surface, to determine the relationship between the tool orientation, the maximum residue level, feed rate and surface morphology of the prediction model of the actual milling speed, and through the orthogonal experiment to determine the tool rake angle are the main factors that affect the surface morphology.5. Comparing the simulation results of the model with experimental results, summarize the design method to obtain the required surface morphology and the tool path and cutting parameters on the surface of the actual.
