<p>Cutting is one of the important technologies in the field of metal machining. Stainless steel is widely used in defense, aerospace, automotive, and other manufacturing industries due to its excellent mechanical properties. However, stainless steel is a difficult-to-machine material characterized by high strength, high hardness, high cutting resistance, low thermal conductivity, elevated cutting temperatures, and difficulty in chip breaking. These properties pose significant challenges to the machining of stainless steel. The formation of long, continuous chips during the turning of stainless steel is a major issue in continuous turning operations. Therefore, to improve machining efficiency and reduce the adverse effects of continuous chips, it is essential to control and break the chips generated during stainless steel machining. This paper reviews the mainstream chip breaking methods in stainless steel turning and divides them into four categories. It compares the advantages and disadvantages of each method, providing a useful reference for future research on chip breaking in stainless steel turning.</p>
