The research results of cutting speed effect on cutting force and chip shrinkage when turning missile parts made of titanium alloy BT6 (Russian State Standard GOST 19807-91, Ti (86.485 – 91.2%, Al (5.3 – 6.8%), V (3.5 – 5.3%) are given in the paper. The influence of cutting speeds on cutting force and chip shrinkage when turning parts made of titanium alloy BT6 (Russian State Standard GOST 19807-91) were experimentally determined. In accordance with test results, the following conclusions were made: cutting speed increase more than 30 m/min is inappropriate as cutting force values do not decrease; it is not recommended to use light feeds and high cutting speeds due to fire safety; increasing cutting speed more than 40 m/min demands either increasing the thickness of material to be removed or the feed rate, otherwise, choosing another plan approach angle φ.
