Abstract

Cutting elastomers is a very common procedure that is used in a wide variety of applications, including rubber product manufacturing, food processing, and surgical process. To conserve energy and improve cutting accuracy, decreasing the cutting force and elastomer deformation is always of interest. Numerous studies have concentrated on methods for reducing cutting force and deformation, but only a few have explained the underlying mechanics of these cutting techniques. Without a deep understanding of elastomer cutting mechanics, it's difficult to improve or develop a new cutting method. To understand the cutting mechanics, the mechanical, tribological, and rheological properties of the elastomer involved in the cutting process will be examined firstly. The properties include the fracture strain under various loading conditions, viscosity, and friction force under various testing conditions. Following that, the cutting mechanics will be investigated in the cutting process based on the strain-based fracture criteria. To have a clear view of the strain distribution of elastomer, an indentation test will be performed rather than a blade cutting test. Additionally, the cutters can minimize the elastomer deformation, and the cutting force will be designed based on the elastomer's properties and cutting mechanics.
