ABSTRACT:
A cutting apparatus for cutting material into a desired shape has a first travelling member and a second travelling member which are arranged on a holding stand, on which the material to be cut is placed, and which approach and separate from each other. A cutting tool for cutting the material is mounted on each of the first and the second travelling members so as to be movable in a direction that is perpendicular to the travelling direction of each travelling member. Movement corresponding to a cutting profile required for the cutting tool to cut the material to a desired shape is imparted by controlling the first travelling member and the second travelling member and the cutting tools mounted on both travelling members. In addition, such a cutting process can be carried out by driving a numerical control to spread the cutting tools mounted on both travelling members in a laterally symmetrical relation so that an annular portion can be cut to produce shaped articles.
