Abstract A new plate cutting machine with single axle and asymmetric negative offset is introduced. The cutting force, compression force of crank arms, backward pushing force for remaining constant blade clearance are analyzed, and formula of asymmetry is deduced. Furthermore, the mechanical characteristics of the negative offset structure is analyzed and a method to determine negative offset range is presented. The theoryetical analysis and practice indicated that the asymmetric negative offset structure is important for increasing cutting quality and prolonging cutting edge life.
