Vibrational trimming of book-edge with an eccentrically installed disk knife

The article examines the kinematic and force parameters involved in cutting paper stacks or book blocks with a disc knife installed with eccentricity. Due to the eccentricity, the knife blade oscillates radially relative to the material being processed, making the cutting process vibrational. Theoretical calculations of cutting forces during block processing have been carried out, and a comparison with experimental results is provided. Additionally, recommendations for designing advanced cutting machines are given.
