Abstract

A cutting apparatus for cutting a workpiece sandwiched in a first direction, wherein a first tool 110 and a second tool 120 are disposed in a first direction so as to face each other, a blade portion 110a of the first tool and a blade portion 120a of the second tool each include a pressing surface S1 perpendicular to the first direction and a first vertical wall surface S2 perpendicular to the pressing surface S1, at least any one of the blade portion 110a of the first tool and the blade portion 120a of the second tool includes a tool inclined surface S3 between the pressing surface S1 and the first vertical wall surface S2, an angle between the pressing surface S1 and the tool inclined surface S3 is an obtuse angle, and a clearance C [mm] between the first tool 110 and the second tool 120 and a distance d [mm] between the pressing surfaces S1 satisfy a formula (A) below: n<C/d<m where, n = 0.3 + (-0.15) × (1-cos4θ), m = 0.4, where, θ [°] is an inclination angle of the tool inclined surface S3 with respect to the first direction.
