Traditionally, the use of ferrite as a core of the linear variable differential transformer (LVDT) is suggested in its designs. Nevertheless, problems related to its brittleness and low tensile strength may be considered as important drawbacks for its use as a core material, especially when its geometry is likely to be modified. This work explores other alternatives related to soft magnetic materials, less used in applications of an LVDT core. By means of a decision matrix, from an assortment of different materials, three alternatives were selected. This proposal provides the identification of those materials with higher qualification values to be used as core material. In order to validate the performance of the selected materials, a prototype of LVDT was designed and fabricated. The design was carried out taking into consideration typical performance specifications. Finally, a comparison of the measurements of sensitivity and linearity of the proposed and traditional materials was made.

Objective: Implement the "filter by magnetic field" and be able to improve the quality of the geometric and visual pieces, returning the properties to the refrigerant (oil) by removing the impurities, and thus being able to improve the efficiency of the machining through this project. Methodology: The device is integrated by a magnetic field filter that was designed to remove the metallic microparticles found in the refrigerant fluid and thereby reduce the geometric and dimensional variation in the specifications of precision machined parts in CNC. A filtering system for the burr of the refrigerant oil is applied by means of an electromagnet. The purpose of this project is to reduce the amount of Scrap by variation produced in the final measurements by premature wear of the cutting tool edge generated by these metal particles suspended in the cooling oil even after being filtered conventionally. This project also aims to extend the useful life of the tools (inserts, bits and shanks), since the durability of the tools is reduced and when they lose the edge they fracture prematurely producing scrap pieces. Contribution: The implementation of the filter would reduce the defect of parts marked by residues inside the refrigerant by 90 percent.

Objective: Design a hydraulic lifting platform through the use of SOLIDWORKS software, to expedite the transfer of boxes of machined material and avoid physical damage. Methodology 1. Analysis of the problem that workers have when moving machined material to their respective work areas, emphasizing the bad manipulation they perform. 2. Description of the different types of mobile personnel lifting platforms (PEMP) that exist in the market. 3. Perform a sampling to specify the average weight that the materials acquire after being machined and justify that they are high loads and difficult to handle without causing physical damage. 4. Study of forces in SolidWorks, with the purpose of observing if, it is a resistant mechanism and if the load you wish to supply will not generate buckling on the beams. 5. Design and molding of a mobile lifting platform, and its validation through the SOLIDWORKS finite element program, which will improve the ergonomics in the distribution of the machined material to its next destination, avoiding irreversible injuries and speeding up said activity. 6. Evaluation of the costs generated by manufacturing the lift table and the economic benefits it will have. Contribution: Avoid physical damage caused by the mishandling of loads and that ultimately generates production problems.
