Abstract
The quality in the production of manufactured products has been a prominent factor and strongly demanded by the industries and clients. In the manufacturing industry, machining centers play a crucial role in obtaining parts with good accuracy and repeatability: dimensional, geometric and profile tolerances close to those specified in the design. This paper seeks to highlight and evaluate how contour errors affect the geometric quality of machined parts by means of a circular interpolation process and thus propose compensation actions. To measure the errors, a measurement system, known as the Ballbar System, was used in a 3-axis CNC machining center. The main errors of this center were evaluated, as well as deviations verified according to ISO 230: 4. The results show the urgent need for corrective maintenance of the machining center.
