Experimental positioning error study on a Cartesian CNC table

Abstract

This paper describes the fundamental criteria for the construction of an automated Cartesian table with an innovative design and aiming to minimize costs while keeping high precision. For this reason, in the design phase, precision, cost, ergonomics as well as safety were considered the most important factors to guarantee a flexible and reliable workbench. During the construction phase, all quality standards were maintained, selecting suppliers with experience in the market, respecting good manufacturing practices and optimizing resources. Subsequently, the bench's systems and subsystems that generate significant effects on the structural elements were validated by means of load simulations. The construction was based on the aesthetics, availability of materials and manufacturing processes of easy access in the market that offered high quality at low cost. It was completed after construction, installation, commissioning and based on the results of the tests, the equipment operated in very good conditions.
