This study investigates wall thickness variations during the multi-stage deep drawing of bearing housings under industrial-experimental conditions. The paper outlines a methodology for evaluating both material formability and wall thickness distribution within the drawn components. KOHAL 240 cold-rolled steel sheet (DC03 drawing quality), nominal thickness of 2mm served as the experimental material. To analyze material flow and thinning behavior, thickness was monitored across three drawing stages. Measurement accuracy was validated by comparing two distinct approaches: conventional manual measurement using a point-contact micrometer and advanced non-contact optical scanning via the GOM Scan 1 and Zeiss ScanPort systems. The resulting data, presented through comparative graphical analysis, demonstrate a high degree of correlation between the optical and manual methods. Observed deviations remained within acceptable experimental tolerances, confirming the reliability of non-contact scanning for monitoring complex forming processes.
