2. Description of the Related Art Conventionally, in a machine tool, pocket machining of an arbitrary shape is performed by designating an arbitrary shape to perform area machining. It is inconvenient in the work to perform. Because there are some data to be input from the screen to specify the shape, and in some cases, the input point is unknown, so auxiliary calculation was required. Further, although the change of the one-point or two-point method of the manual cutting function is performed by the system parameter, since the setting and changing operations are complicated and difficult, a polygon pocket machining input method that can be easily set is desired. There is.
