MESA-PALACIO, Leonardo de J.; CALLE-TRUJILLO, Gabriel  e  ARBELAEZ-TORO, Juan J.. Diseño, Construcción y Fabricación de una Máquina Prototipo de Medición por Coordenadas. TecnoL. [online]. 2011, n.26, pp.11-25. ISSN 0123-7799.

This 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.
