Evaluación de la tecnología de mecanizado para elementos de geometría compleja mediante el trabajo de 5 ejes simultáneos

Abstract

The objective of this technical project was to evaluate the machining technology for elements of complex geometry through the work of 5 simultaneous axes, this technology being little developed in the country because there is no adequate software, as well as qualified personnel for its management. By using the ROMI DCM 620-5X 5-axis CNC milling machine located in the “CAD CAM CAE” laboratory of the Faculty of Mechanics, the machining of an impeller was carried out, this being a complex geometry, defining it as one that simply vista is considered rare because it is not formed by simple geometries such as cubes, cylinders that are developable and the sphere as non – developable, thus having a difficulty in machining. The control of the machine is carried out by means of the numerical control SIEMENS SINUMERIK 840D through which it is possible to read and interpret the G code obtained by means of the compatible post processor, once the simulation has been carried out in the software to check if the chosen tools are adequate, in addition to the control of speed and position of the 5 axes. Concluding that the results obtained in the machining of the impeller are satisfactory since when compared with the values of the CAD model, it is within the range of deviation allowed by the IEC 6019 standard; managing to make the six blades with their respective splitters, demonstrating that through this technology it is possible to machine them in a single assembly in short times and the notable decrease in errors due to human error, it is recommended to review the manual of the machine and the use of Personal Protection Equipment for its handling, as well as the appropriate tooling and clamping system for correct machining.
