Dynamic Management of Additive Shaping Process with the Use of 5-Coordinate Processing Equipment

Purpose of research. The study is about  accuracy of surface layer formation of mechanical engineering products by additive method. Advantages and disadvantages analysis of layer-by-layer synthesis technologies of products was done. It was identified that accuracy characteristics of surface layer under additive shaping significantly differ from accuracy characteristics of products' surface layer otained by traditional methods.  

Methods. Surfaces shaping of complex details by additive methods is characterized by high static values of processing error. Processing error is a shaping error (approximatio). Analysis of Russian and foreign literature was done. It was offered to carry out dynamic spatial orientation of a final element of a form-building system of the additive equipment. It was offered for increase in accuracy characteristics of products' received by additive methods. It was offered to use 5-coordinate processing equipment for spatial orientation management of a final element of a form-building system. Calculation method of operated parameters of 5-coordinate processing equipment was developed. Spatial orientation of a final element of a shaping system will be at these parameters. The orientation will be according to normals in a point of nominal surface of a shaping detail..  

Results. Operated parameters determination of 5-coordinate processing equipment when shaping a hemispherical surface was done by additive methods.  Graphic dependences are results of mathematical modeling. They reflect the size of tilt angles of 5-coordinate processing equipment desktop. Platform turn with a detail at hemispherical surface shaping of a detail by additive methods was also reflected.  

Conclusion. The offered technique allows carrying out dynamic spatial orientation of a final element of a shaping system of additive equipment. This can reduce shaping error (approximation) of figurine details' surfaces in the process of their shaping by additive methods.
