Badanie dokładności pozycjonowania i diagnostyka tokarki CNC

Celem badań było przeprowadzenie pomiarów dokładności pozycjonowania i diagnostyki tokarki sterowanej numerycznie CTX 410 Gildemeister. Do pomiarów dokładności pozycjonowania wykorzystano Interferometr Laserowy XL-80, a do diagnostyki „Szybki Test” Ballbar QC-10. Analiza uzyskanych pomiarów wykazała, że wartości mierzone nie mieściły się w tolerancji wartości dopuszczalnych dla tej obrabiarki.

The aim of the research was to make measurements and diagnostics positioning of a numerically controlled lathe-Gildemeister CTX 410. An interferometr laser XL-80 was used for measurements of the positioning accuracy. The roundness test and diagnostics were carried out using "Quick Test" Ballbar. The first section of the paper lists the reasons for inaccuracies of machines and why they are so important. There is the basic information about the testing equipment which enable their measurements. In the next section the equipment is described in details. There is also described the method of installation and testing process. For each type of measurement the equipment configuration was different. It was determined by the workspace and machine capabilities. Section 3 contains some results of investigations. The analysis of the measurements shows that the measured values do not fit in the tolerance limits for this machine.
