Diseño, construcción y fabricación de una máquina prototipo de medición por coordenadas
AbstractThis work is framed as a case study of theoretical and practical. The metrological verification of frame parts type style is done through measurements and calibrations tables. This procedure requires time in the assembly and precision gauges. The research aims to design and build a prototype machine coordinate measurement (CMM) to assist in the verification metrology frame type of motorcycle parts. Based on the determination of the accuracy required in the manufacture of frames: select the structure of the CMM is selected, the geometric tolerances applied to the construction of the frame of the CMM are defined, the dimensional chains and the principles of operation of the system settings and tolerances are analyzed, are manufactured and build the pieces that conform the CMM are manufactured and built. Subsequently, the gathering, verification and display system is designed. Finally, we proceed to the calibration of the CMM, allowing identifying the error and uncertainty of the CMM. The procedure ensures design, construction, and manufacturing of a prototype machine type coordinate measuring bridge capable of measuring a maximum length of 250 mm with a minimum tolerance of ±0.3 mm.
