摘要 |
A protrusion forming device includes a holding portion holding an object that is be processed, a tool bit having a cutting portion capable of cutting an object held by a holding portion, and a drive portion capable of driving the tool bit. The tool bit is movable along a cut-in pathway so that the cutting portion is inserted into the object. The cutting portion is movable along a further-cut pathway so as to form a protrusion part that is cut in a linear shape and is connected to the object. The tool bit continuously contacts the protrusion part while moving along a forming pathway such that the protrusion part extends perpendicular to an outer surface of the object.
