Design of an automated XYZ Cartesian table with interchangeable head for cutting through plasma and oxyfuel

Abstract

This document describes the fundamental criteria in the design of a Cartesian table automated with three axes XYZ with an interchangeable head to work with plasma cutting and oxyfuel, as the selection of the processes implemented for its construction. For this the table splits into four fundamental parts; X axis, Y axis, Z axis and control system. It is begun by a conceptual design in which the basic dimensions of the table are defined and a counterfoil of selection of components is realized, then in a detailed design to determine the dimensions and exact characteristics of every component. Later, the systems and subsystems of the table, that generate significant effects on the structural elements, were validated by means of charges simulations. The elements selection was based on the esthetics, availability of materials and processes of manufacture of easy access on the market that were offering high quality to low cost. In order to conclude, with the detailed design in this document, it is possible to construct a table CNC with high precision and low cost.

Development of a CNC plasma cutting machine: design and construction for didactic purposes

“…This involves selecting and sizing the components, such as linear rails, stepper or servo motors, ball screws and drive units. The design must take into account the desired working area, the rigidity of the structure and other specific requirements for plasma cutting (RAMOS et al, 2018).…”
