Desarrollo de un prototipo de fresadora portátil para prácticas de laboratorio

Abstract

The objective of this project is the development of a prototype of a portable milling machine focused on teaching machining processes for technical and university students. The prototype provides an accessible learning platform for students to understand how milling machines work. The prototype has been designed and manufactured in SolidWorks, with a structure built in high-density pol yethylene (PE), which guarantees a lightweight and resistant structure. The milling machine will machine nylon, using 6 mm diameter high-speed steel (HSS) cutting tools, including both a milling cutter and a drill bit. For the drive of the spindle, a DC motor of 12V with a system of holder and support is used, allowing the use of different cutting tools, the motor speed is regulated by an electronic controller and a switched source, this makes it possible to vary the cutting speed according to material requirements and machining conditions. In addition, the feed system is manual using a crank, which facilitates the student’s direct interaction with the milling process and improves their understanding of machining control.
