Abstract
For the function of forming numerical control information prior to machining process, the type of machining (such as drilling, end milling, outer diameter end face, etc.) and machining scope for each machining area is determined by inputting the shapes of a work and a part determining the machining areas based on said shapes, identifying the areas for inner diameter machining out of said machining areas, extracting from said inner diameter machining areas those characteristic areas to the inner diameter machining such as the area where a rear end face exists on the part shape, where a through hole is unprocessed or where a through hole is bored on the work based on the shape elements. As this method does not require preliminary reviewing of the machining method for inner diameter (and especially for small diameter), it allows beginner operators to produce numerical control information as easily as a skilled operator.
