Description

  The present invention relates to a plate material processing apparatus that forms a slit in a plate material by a router.

When a through-hole having a desired shape and size is formed on a plate material such as a plywood, a cutting tool called a router capable of performing groove processing may be used (see, for example, Patent Document 1). In this case, after cutting the router so that it penetrates from the front surface of the plate material toward the back surface, the router is cut from this processing start point while moving along the edge of the through hole to be formed parallel to the surface of the plate material. By returning to the processing start point again, a through hole having a desired shape and size can be formed in the plate material.
