Transforming Art into Science

Once the operator sets the ideal cant angle for the material, do not adjust it during the run. Changing cant angles during a production run will change the wear pattern on the blade (in effect, rounding the blade corner), making it impossible to get back to the original setting without changing blades. The cut point will shift and repeatability will rely on the art of the operator, rather than the science behind the equipment. As slit quality begins to deteriorate, the operator may try to increase cant angle to generate more bite. While this can temporarily improve slit quality, it will increase wear between the blades and result in a lower quality cut.
