 The study investigated the effectiveness of thermal pulse deburring for small-sized parts made from beryllium bronze and the 29 NK alloy. The study found that the root of the burr can be limited if certain cutting parameters are set. These parameters include the feed rate, depth of cut, and speed of rotation. Setting these parameters within the recommended ranges allows for effective thermal pulse deburring of small-sized parts. This article was authored by Nikita V. Martyachev, Dmitry A.
