Embodiment approach 1

[0023] figure 1 It is a figure which shows the functional structure of the numerical control device 1 concerning Embodiment 1 of this invention. The numerical control device 1 has functional units such as an operation monitoring unit 11 , a comparison unit 12 , a notification unit 13 , a machining control unit 14 , and a storage unit 15 . The operation monitoring unit 11 has an operation recording unit 111 . The storage unit 15 has a first storage unit 151 and a second storage unit 152 . The numerical control device 1 is connected to an input operation unit 2 for an operator to perform an input operation, and a display unit 3 capable of outputting a display screen to the operator.

[0024] The operation monitoring unit 11 receives operation information indicating the content of the input operation from the input operation unit 2 , and monitors the content of the input operation. Specifically, the operation monitoring unit 11 inputs the operation information to the compariso...

Embodiment approach 2

[0041] Image 6 It is a figure which shows the structure of the control system 100 of the numerical control device 1a-1, 1a-2 concerning Embodiment 2 of this invention. The control system 100 includes numerical control devices 1 a - 1 , 1 a - 2 , and an information processing device 7 connected to the numerical control devices 1 a - 1 , 1 a - 2 via a network 8 . Numerical control devices 1a - 1 and 1a - 2 each have an operation monitoring unit 11 , a notification unit 13 , a machining control unit 14 , and a communication unit 16 . The information processing device 7 has a comparison unit 72 , a storage unit 75 , and a communication unit 76 . The storage unit 75 has a first storage unit 751 and a second storage unit 752 . In the following, when there is no need to distinguish the numerical control devices 1a-1 and 1a-2, the numerical control devices 1a-1 and 1a-2 are simply referred to as the numerical control device 1a respectively.

Abstract

The numerical control device (1) is characterized in that it includes: a machining control unit (14) that executes a machining program to control the machine tool (4); an operation recording unit (11) that records the operation information indicating the content of the input operation The first operation history is generated, and the operation information when abnormality occurs in the operation information is recorded in association with the processing program executed when abnormality occurs to generate the second operation history; and the notification unit (13), When an input operation instructing execution of a machining program is received, and the current input operation is determined to be an abnormal operation using the second operation history, the machining control unit notifies the execution of the machining program but notifies a message.

Description

technical field [0001] The present invention relates to a numerical control device and an information processing device for controlling a machine tool by executing a machining program. Background technique [0002] In recent years, numerical control devices that execute machining programs to control machine tools have become widespread. When an inappropriate input operation is performed by the user to the numerical control device, abnormalities such as machining failure and mechanical disturbance may occur. [0003] Patent Document 1 discloses a numerical control device having a function of storing in advance operation mode information defining combinations of input operations that may cause abnormalities, and combining received input operations with the stored operation mode information. The input operations defined in are compared to prevent exceptions in advance. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2011-154607 Contents of the invention [0005] ...
