Under this premise, this project addresses the design of a prototype high-pressure hydrodynamic cutting machine with automated movement, with the aim of improving the operating conditions of the Mechanical Workshop of the Technological Faculty of the Francisco José de Caldas District University. The proposed system is based on the principles of fluid mechanics, high-pressure hydraulics, and automation, integrating a positive displacement pump capable of generating pressures of up to 350 bar, a precision nozzle, and a guidance system driven by NEMA 23 stepper motors. A cutting head was designed to channel the fluid through a nozzle, allowing the sectioning of low- and medium-hardness materials without generating heat or altering the microstructure. CAD/CAE modeling and simulation tools such as ANSYS Fluent were implemented to develop the prototype to validate fluid behavior and analyze pressure and velocity distribution in the outlet channel. Selection criteria and dimensional constraints were also considered, ensuring durability, mechanical compatibility, and ease of maintenance. The result is a design geared toward both educational and pre-industrial needs, notable for its modularity, ease of operation, dimensional accuracy, and relatively low-cost construction feasibility. The solution offers a safe, ergonomic, and technically robust alternative to traditional cutting methods currently used, increasing efficiency, precision, safety, and quality in part cutting.Ítem Elaboración de procedimientos de mantenimeinto para la comercializadora de maquinaria industrial Aeromaquinados SASOrtiz Calderon, Juan Sebastian; Gonzalez Colmenares , MauricioThis project implemented in an industrial machinery marketer that provides technical maintenance service, is focused on the need to strengthen and establish a formal system for the reception of information in maintenance technicians on the ways of working that the company handles, for this the most frequent maintenance tasks in the company will be identified to be documented step by step. a process that will be guided under the parameters established by the appropriate professionals within the company.

These can be presented in 2 and 4 stroke otto cycle or Diesel cycle among others. Over the years their designs and efficiencies have improved exponentially, however, their efficiency still remains above 30%, which implies that a large part of the energy generated is not used and is lost in different forms such as heat. This work details how the process of diagnosis, repair, maintenance and operation of various components was carried out, such as: radiator, water pump, carburetor, gasoline pump, thermometers, electrical panel among others, which make up the test bench corresponding to the engine with reference C1E arranged in the internal combustion engine laboratory of the technological faculty of the Francisco José de Caldas district university, which allow the operation of the test bench. In turn, it is evident in the diagnosis process that the main failure of the test bench is the lack of maintenance and deterioration of components over the years. Likewise, the durability of other components is checked, such as: the structure that supports the engine, the block, cylinder head, pistons, exhaust manifolds, etc. In addition, it allows you to know the different elements that contribute to the operation of the engine in a theoretical-practical way, understanding each of these components and the role that each one of them plays.Ítem Propuesta de mejora mecánica para un molino penagos TH-6(Universidad Distrital Francisco José de Caldas) Poveda Blanco, Miguel Angel; González Colmenares, MauricioThis project proposed a mechanical improvement for a sugar cane mill, focusing on increasing its extraction efficiency.
