[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Existing edge-cutting inspection processes for sheet metal used in automobile manufacturing often involve placing an inspection bracket on an inspection platform and then placing the part on the bracket before starting the inspection.
