This article presents the results of laboratory tests involving the measurement of cutting forces during the orthogonal turning of a tube made of GRADE 2 titanium alloy. The nominal diameter of the turned tube was D = 60 mm, and its wall thickness was 2.77 mm. For research purposes, a Kennametal chisel with an insert marked A3G0500M05P04DF and a holder marked A3SAR2520M0425-075-100 was used. An experimental research plan for variable cutting parameters (
