A numerically controlled apparatus for a machine tool has a tool and machining condition automatically controlling function, and stores standard data of tools and machining conditions in a standard database. The input device of the apparatus inputs the users data of tools and machining conditions other than the contents of the standard database, and the apparatus stores the data inputted with the input device in one or more user databases. The tool and machining condition automatically determining function of the apparatus determines tool and machining condition data by utilizing both of the standard database and one or more the user databases.

Numerical control apparatus for a machine tool

A machine tool is controlled in response to a numerical control program that is indicative of tool path data. A user selects a working region on which the machine tool will operate. A portion of the tool path data that corresponds to the selected working region is determined, so that both the selected working region and the portion of the tool path data may be displayed on a display. Such a display may also include a grid so that the user may select grid areas. Grid areas may be selected so that only data associated with the selected grid areas is modified, or to allow the user to modify a visible outline of the area to be worked, or to allow the user to select non-workable regions for which the original tool path data will not be modified. Further magnification may be based upon a predetermined magnification rate or a magnification rate selected by the user.

Numerically controlling apparatus for the machine tool

An automatic production line control data forming system for use in a production design, control and preparation system for a production line comprising: a process planning system for inputting data such as configurations and tolerances which are provided on drawings, and performing a process planning operation with reference to production machine data; a production scheduling system for making day's schedule plans; and an automatic programming system for forming programs for production machines such as NC machine tools and robots. In the automatic production line control data forming system, configuration data and machining features of parts which have been formed during process planning are subjected to formal conversion and transmitted to the automatic programming system, to allow the automatic programming system to form NC programs; or the kinds, the numbers and the delivery dates of parts to be manufactured during a given period which are provided as an article production plan, and data on production machines for machining the parts and machining time therefor which are formed during process planning are subjected to formal conversion and transmitted to the production scheduling system, to allow the production scheduling system to form day's schedule plans.

System for forming automatic production line control data

A method of automatically deciding procedure for machining parts, in which the parts configuration data is input. The input parts configuration data is compared with a plurality of predetermined ordinary parts data which correspond to a plurality of predetermined patterns of the machining processes, respectively. One of the predetermined patterns is determined as a design of the machining process corresponding to the input parts configuration data. Machine tools and machining specifications for each process of the determined patterns are determined in accordance with the input parts configuration data.
