Cyber-physical Modeling of High Speed Machining of Flexible Materials

Abstract

Due to the structure characteristics of flexible materials, it will easily be deformed in the cutting process and thus the cutting interface be destroyed, resulting in low-quality cutting parts. Based on the cutting process of flexible leather substance, this paper attempts to develop a new high speed vibration cutting mechanism for flexible materials. Research will be on the vibration cutting method for flexible materials, and then a high speed vibration cutting head module will be designed according to motion transformation principle of eccentric shaft and connecting rod structure. Corresponding tests and Experiments are carried out and as the result, the vibration cutting frequency is up to 20,000 times/min, with the angle error within ±1.5°. The cutting speed can achieve 120 cm/s, and work noise < 80db.
