Diseño y estudio de parámetros para la fabricación de un portaherramientas para torno CNC.

Abstract

The objective of this project is to define the design parameters for the elaboration of a toolholder in the ROMI D800 CNC machining center of the Faculty of Mechanical Engineering of the National Polytechnic School. For this, it was necessary to: identify the toolholder that meets the desired machining requirements, choose the material with which the toolholder machining is assumed based on the easy acquisition and costs in the near area, perform the calculation and simulation of strains to ensure that the design does not fail when applying the loads that occur during turning, perform CAM machining operations programming and compare manufacturing costs against the cost of the toolholder in the market. The chosen toolholder is SVJBR 2525M 16 from Sandvik, the material with which the construction is assumed is AISI 1018 steel, which is recommended for the construction of toolholders, the simulation is validated by comparing the strains resulting from the simulation with those calculated manually and checking that the error between them must be less than 25%, which is a maximum value allowed as indicated by Abaqus/CAE 2021 in its student version. On the other hand, the manufacturing cost compared to the cost of the toolholder in the market is lower and the machining time is less than 3 hours, which is convenient compared to the waiting time in case of having to import the toolholder for purchase.
