Abstract
A numerical controller includes a coordinate management unit that updates machine origin offset data indicating a positional relationship between a machine origin of a machine tool and a machine origin of a robot depending on movement of the machine origin of the machine tool or the machine origin of the robot; and an interference check processing unit that detects interference between the machine tool and the robot on the basis of a position of a first interference definition area and a position of a second interference definition area, and the updated machine origin offset data.
Claims10
A numerical controller that controls a first industrial machine having a first coordinate system and a second industrial machine having a second coordinate system and being movable, the numerical controller comprising:
- a coordinate management circuitry to update machine origin offset data indicating a positional relationship between a first machine origin that is a machine origin of the first industrial machine and a second machine origin that is a machine origin of the second industrial machine depending on movement of the first machine origin or the second machine origin;
- and
- an interference check processing circuitry to detect interference between the first industrial machine and the second industrial machine on a basis of a position in the first coordinate system of a first interference definition area obtained by modeling the first industrial machine, a position in the second coordinate system of a second interference definition area obtained by modeling the second industrial machine, and the updated machine origin offset data.
An industrial machine control system comprising a first industrial machine having a first coordinate system, a third industrial machine having a third coordinate system, a second industrial machine having a second coordinate system and being movable, a first numerical controller to control the first industrial machine and the second industrial machine, and a second numerical controller to control the second industrial machine and the third industrial machine, wherein
- the first numerical controller includes:
- a coordinate management circuitry that updates first machine origin offset data indicating a positional relationship between a first machine origin that is a machine origin of the first industrial machine and a second machine origin that is a machine origin of the second industrial machine depending on movement of the first machine origin or the second machine origin;
- and
- an interference check processing circuity that determines whether the second industrial machine has entered a work area of the first industrial machine, and, in a case where the second industrial machine has entered the work area of the first industrial machine,
- detects interference between the first industrial machine and the second industrial machine on a basis of a position in the first coordinate system of a first interference definition area obtained by modeling the first industrial machine, a position in the second coordinate system of a second interference definition area obtained by modeling the second industrial machine,
- and the updated first machine origin offset data.
