Chip Breaking Optimization During Turning Shoulder

Sammanfattning: Poor chip breaking is a normal problem in the field of machining in many manufacturing plants. The researches on chip control has started from the early 1900s, it has developed for more than one hundred years and researchers are still working on it to establish a ‘total’ chip control system. The purpose of this project is chip breaking improvement for reducing downtime and further increasing OEE, because of the problems long chips that cause during a soft turning process. This thesis provides basic theories and existing methods for chip breaking which are helpful to understand chip breaking and to generate solutions for chip breaking optimization. During the project, five concepts are generated and two concepts are tested which are presented in this report. The concept ‘multiple tool paths’, which was verified by tests, could successfully reduce the length of metal chips and improving the performance of chip breaking.
