ABSTRACT:
It is an object of the invention to provide a reverse rotation preventing electronic cam curve generating method of an electronic cam type rotary cutter control which serves to prevent the reverse rotation of a cutter.According to the invention, there is provided an electronic cam curve parameter setting unit28for previously calculating a critical cutting length Ljagfrom which an electronic cam curve passing through a point having an acceleration of 0 and a speed of 0 is obtained by setting a rotor diameter r of a rotary cutter5,the number of blades M disposed at regular intervals on a rotor, synchronizing speed coefficients β1and β2for regulating synchronizing speeds in cutting, and synchronizing angles θ1and θ2, comparing the critical cutting length Ljagwith a set cutting length Lsetof a processed product set by an operator, and generating an electronic cam curve pattern for preventing a reverse rotation when the set cutting length Lsetis greater.
