Diseño y fabricación de la cadena de protección de cableado de la máquina Bridgeport de la EII. Mediante impresión 3D.

Abstract

This degree project is focused on the construction of spare parts of chain for protection of wiring of the machine Bridgeport of the laboratory Computer- Aided Design – Computer - Aided Manufacturing (CAD – CAM) of the school of Industrial Engineering, by applying a new technology of construction using a 3D printer which consists in the creation layer by layer of three-dimensional objects from a digital design using a material in the form of a filament. The design of the chain is made from the original chain to ensure that its measures are accurate; previously in the design program is verified that the components have the appropriate measure by an entire assembly. The material selected for the manufacture is Polylactic Acid (PLA) by being a material that provides excellent mechanical and technological properties. The printer used is of CREATOR brand which is very commercialized in the market whit great guarantees of functionality and operation. The printer reads a code similar to the machines of technology Computerized Numerical Control (CNC); for this reason, it is necessary that the model be exported in a Stereo Lithography format (STL) because it is a computer file format that geometrically defines a 3D object excluding color information, texture or physical properties, the final process is to generate these codes in a free external program, the chain is printed whit a fill percentage of 90%. At the end of the construction a chain was obtained with great resistance and whit exact measurements, when the chain was placed in the machine it was verified that complies whit all of the features of protection.
