Mejoramiento del proceso de obtención de planchas de mármol mediante reingeniería en la máquina de corte para la empresa Grani Mármoles MJ Cantón Riobamba

Abstract

The company "Grani Mármoles MJ", located in Riobamba city, confronts a critical challenge in its production area due to an improperly functioning marble cutting machine. This situation is the result of some modifications made to the original configuration of the equipment, which have resulted in a significant deficiency such as irregular cuts and dimensions outside the specified tolerances. These deficiencies have led to complications in subsequent assembly processes. In order to face this problem, the main objective was to improve the process of obtaining marble slabs by reengineering the cutting machine for the company Grani Mármoles MJ. The methodology followed is categorized as an applied research, designed to solve a specific problem, incorporating both quantitative and qualitative approaches. The research design is framed in the action research model, involving operators and technicians. A systematic observation method is employed, complemented by interviews. A checklist applied to the staff responsible for the operation and modification of the cutting machine is being used as the main control and evaluation instrument. After the detailed characterization of the requirements for the reengineering implementation, a CAD model was developed and validated through simulations and static analysis in SolidWorks software in its academic version, therefore ensuring the feasibility and effectiveness of the proposed improvements before their physical implementation. The semi-automatic marble slab cutting machine was built and assembled, reaching a longitudinal cutting capacity of 2500 mm in 90° and 45° angles, with a constant speed of 1.25 rev/s and a time of 54.24 seconds in double cut, thus meeting the specific requirements of the company.
