    The purpose of this research work was to develop a technical management plan for mechanical risks for the machining area of the company GT Rectificadora, which sought to strengthen current safety conditions and reduce the exposure of workers to mechanical hazards. The research was carried out due to the presence of unsafe conditions during machinery operation, exposure to rotating systems, and the use of cutting tools during the grinding process. To analyze the current situation of the company, a checklist was applied whose regulations were based on questionnaires provided by the INSST, where 3 categories were evaluated: tools, machinery and the work environment, where the results reflected a 60% non-compliance in tool criteria, 71% in machinery and 100% in work environment, highlighting mainly the non-compliance in the machinery category due to the absence of physical guards, maintenance and safe procedures. For the estimation and evaluation of risk, methodologies such as GTC-45 and William T. Fine were used, which showed the presence of high criticality risk, such as impacts, cuts, entrapment, and projection of particles in grinding, turning, and honing operations. Thus, a management plan to prevent mechanical risks was proposed, incorporating engineering, administrative, and PPE controls for the identified risk to prevent accidents in the work area.

    Manufactura esbelta y su aplicación en el mejoramiento continuo del proceso productivo de templado de vidrio de la empresa SEGUVID

    The purpose of this research work is to analyze the lean manufacturing tools and their application in the continuous improvement of the glass tempering production process of the SEGUVID company. Talking about continuous improvement refers to the constant elimination or reduction of waste, which will not add value to the final product, so that the company is strategically positioned in an advantage over its competition, this through the efficient use of lean manufacturing tools. Due to the company's production lines, an ABC analysis of two (2) levels is carried out in order to select the line with the highest demand and the glass thickness with the highest requirement, resulting in clear structural glass of 10 millimeters with four perforations with a diameter of 19 millimeters. For the analysis of the tools, the collection of process information is required, therefore, a time study is developed that serves as the basis for the development of the value flow map, the identification of waste and, consequently, the approach of a proposal that allows continuous improvement. The identified wastes cover a total of four being these: (1) Waiting, (2) Transportation, (3) Inventory and (4) Reprocessing, for which an improvement proposal is established using lean manufacturing tools such as Process Optimization. Process to reduce the standard time by 40.00% in the cutting process, Visual Control to improve the flow of documents and production orders, Line Balancing to improve the theoretical daily production capacity from (189.16 to 284.02) m 2, Poka Yoke to avoid reprocessing in the drilling area, 5S to generate a harmonious work environment and Plant Distribution to reduce the cost of glass transportation, which goes from $0.60 to $0.48.
