The effectiveness of selective laser shaping of parts in mechanical engineering
The article deals with improving the efficiency and quality of the selective laser sintering and prototype stages are considered: the prototype preparation, construction of the prototype and prototype finishing treatment.. The method of splitting the model into layers of different thicknesses, which allows to increase the productivity of the process of building a prototype, without considering the magnitude of the resulting roughness. Showing thickness calculations, the performance of the laser sintering, the thermal processing speed, the time of construction of the final prototype simplified. Identify the relationship between modes of operation of the laser and the trajectory of the laser spot scanning speed layers of pulse repetition frequency. Also found that increasing the pulse step reduces processing time and therefore it increases the performance of the prototype building process, but decreases spots unit area and the resulting layer, and hence the surface roughness is increased.
