Abstract

An autonomous control system having a numerical control device configured to perform machining operation by driving control of an item in a machining tool and an external device, the numerical control device includes a configuration data storing unit configured to store configuration data representing configuration of the item, and a machining program looking-ahead processing unit configured to generate item disposition data, and the external device includes a work information storing unit, an interference determination processing unit configured to command start of operation of the external device at time when the operation of the external device does not interfere with the item driven in the machining tool.

First claim

1 . An autonomous control system having a numerical control device configured to perform machining operation by driving control of an item in a machining tool based on machining program and an external device configured to operate interlocking with the machining operation of the machining tool, the numerical control device comprising:
a configuration data storing unit configured to store configuration data representing configuration of the item; a machining program looking-ahead processing unit configured to generate item disposition data including disposition of the item in the machining tool of the machining tool and holding time for the disposition of the item, based on the machining program and the configuration data; and a data output unit configured to output the item disposition data; and the external device comprising: a work information storing unit configured to store space data including information of work space occupied and work time required when the external device works in association with each other; an interference determination processing unit configured to command start of operation of the external device at time when the operation of the external device does not interfere with the item driven in the machining tool, based on the item disposition data output by the data output unit, the space data, and the work time; and a program execution unit configured to start the operation of the external device based on the command from the interference determination processing unit.

2 . An autonomous control system according to claim 1 , wherein
the machining program looking-ahead processing unit is configured to read the machining program before machining is performed and generate the item disposition data before the machining operation, and the data output unit is configured to output the item disposition data in synchronization with the machining operation based on the machining program.

3 . An autonomous control system according to claim 1 , wherein the work time of the external device is sum of time required for work of the external device and margin time.

4 . An autonomous control system according to claim 1 , wherein
an internal clock of the numerical control device and an internal clock of the external device are set to same time, and the holding time is defined as time range.

5 . An autonomous control system according to claim 1 , wherein
the configuration data and reference point of the configuration data are shared by the numerical control device and the external device in advance, and the disposition of the item included in the item disposition data is defined using the reference point of the configuration data.

6 . An autonomous control system according to claim 1 , wherein
space in the machining tool is modeled as a set of a plurality of regions divided by grid, the numerical control device and the external device share coordinate information representing position and space range of the plurality of regions in advance, and the disposition of the item included in the item disposition data is defined by the coordinate data in a region where the item interferes.

7 . An autonomous control system according to claim 1 , wherein
the configuration data representing the configuration of the item is polygon type configuration data representing three dimensional configuration of the item, and the item disposition data, and the space data are defined using data of three dimensional coordinate system.
