RT Journal Article SR Electronic A1 Zawada, Artur A1 Markiefka, Mateusz T1 Detection of Straightness Deviation on a Production Machine in an Automatic Cycle JF Acta Mechanica Slovaca YR 2025 VO 29 IS 1 SP 22 OP 27 DO 10.21496/ams.2025.008 UL https://www.actamechanica.sk/artkey/ams-202501-0003.php AB The article presents a method of measuring straightness of a metal flat bar on a production machine in an automatic cycle. The measurement was carried out while the production machine was operating, using a laser profilometer. In order to determine straightness, the measurement results were used along the entire length, the maximum deviation was calculated and presented, defining whether the measured part meets production requirements.
