    This degree work addresses the design and construction of a CNC Router for milling aluminum for the company IMPRONIC SOLUTION, by creating the parts in the software fusion 360 which were printed in PLA carbon fiber coated with liquid epoxy resin to increase its hardness to a degree of 90 on the Shore D scale, also used stepper motors nema 17 for the movement of the 3 axes that has the machine, the same that increased its initial torque by a factor of 3. 38 by coupling them to a motion transmission system by means of pulleys and metallic gears, for this the controller card that is responsible for sending the PWM pulses to each motor is the MakerBase DLC 2.1 with their respective DVR8825 drivers, which once calibrated generate the movement with a maximum torque of 2.12Nm, it should be noted that the X axis to support the entire structure has 2 motors coupled in similar conditions to obtain a torque of 4.24Nm. In the first instance, the information of CNC machinery available in the national and international market was compiled, in this way it was determined that the accuracy required to match the working conditions is 0.05mm, Afterwards, the simulation was generated in the software where the maximum load that can be supported in each of the axes was determined according to the selection of the aluminum profiles for the base structure. In the electronic section, the reference voltages for each motor were set at 1.875V for both the Y axis and the Z axis, unlike the X axis, which will use a reference voltage of 3.75V. Next, the open platform Universal G-Code Sender software was used, in which the G-code was generated from a loaded design, where the feed rate was delimited according to the material to be milled, the same has a range of 10mm/s to 50mm/s. Finally, tests were carried out with materials such as wood, aluminum and fiberglass
