The reliability of continuous turning process is a significant necessity of mass production and automatic manufacturing systems. Long chips are the main problems for the continuous turning operations and chip break is difficult during the machining of ductile steel and superalloys. Chip formation during machining negatively affects worker and tool safety, workpiece quality, tool life, and energy consumption while also reducing operational efficiency. To alleviate such problems, continuous chips formation during machining must be controlled through chip breaking. As part of this study, various chip breaker designs and approaches to chip breaking were evaluated. The study analyzes the problems associated with continuous chips and compiles knowledge of the mechanics involved in, and the methods developed to handle chip breaking. The methods for breaking continuous chips were categorized into five sections. Different methods were contrasted against each other, the pros and cons were presented and the results were given in a comparative table.
