Abstract

The present invention provides a production control system which ensures easy storage and management of information, and prompt and proper retrieval of necessary information in production sites. The production control system comprises a plurality of terminals provided in production sites and a central processor (5) connected to the terminals via a network (2). The central processor (5) comprises a production control information storage section (7,8,9) which stores information on production control, and a data distributing section (6) for retrieving production control information from the production control information storage section (7,8,9) in response to a request from any of the terminals and transmitting the retrieved production control information to the terminal having requested the information. The production control system can centrally manage the production control information on a paperless basis, and promptly and properly retrieve the necessary production control information.

Claims

1. A production control system, comprising:

a plurality of terminals provided in a plurality of production sites; and

a central processor connected to the plurality of terminals via a network, wherein the central processor comprises;

a production control information storage section which stores information on production control; and

a data distributing section for retrieving production control information from the production control information storage section in response to a request from any of the terminals and transmitting the retrieved production control information to the terminal having requested the information,

wherein the terminals are each incorporated in a numerical controller of an NC machine tool being assembled.

2. A production control system as set forth in claim 1, wherein the production control information stored in the production control information storage section includes at least one of production instruction information on production instructions, process specification information on process specifications and inspection information on inspections.

3. A production control system as set forth in claim 1,

wherein the production control information storage section stores at least inspection information,

wherein the data distributing section receives data indicative of results of an inspection carried out on the basis of the inspection information from any of the terminals,

wherein the central processor further comprises an inspection data storage section for storing the inspection result data received by the data distributing section.
