The study deals with the development of an integrated main processor of 6-axis control CAM system. The 6-axis control machining, where non-rotational cutting tools are used, has a lot of advantages, compared with the conventional one with rotational cutting tools. The main processors, which have developed till now, can generate CL data corresponding to the kind of 6-axis control machinings such as smooth machining, grooving, character line machining, sharp-edged corner machining, pocket machining, etc. However, it is not convenient to prepare the main processor for each 6-axis control machining method. To solve the problem, the integration of the main processors is intended, where CL data corresponding to specific machining method is automatically generated on the basis of judgment of the shape pattern standing for the kind of 6-axis control machinings. As a result, it was experimentally confirmed that the integrated main processor has the potential to select the suitable 6-axis control machining method and generate the corresponding CL data.
