Technical Field

The present invention relates to a numerical control device and an information processing device that execute a machining program to control a machine tool.

Background

In recent years, numerical control devices that execute machining programs to control machine tools have become widespread. When an improper input operation is performed by a user to the numerical control device, an abnormality such as a machining defect or a mechanical disturbance may occur.

Patent document 1 discloses a numerical control device having a function of storing operation pattern information defining a combination of input operations that may cause an abnormality in advance, and comparing a received input operation with an input operation defined in the stored operation pattern information to prevent an abnormality from occurring in advance.

Patent document 1: japanese patent laid-open publication No. 2011-154607

Disclosure of Invention

However, in the numerical control device described in patent document 1, it is necessary to generate operation pattern information in advance in consideration of the possibility of occurrence of an abnormality from among a large number of operation patterns that a user may possibly perform when operating the numerical control device, which requires a large amount of work. In the numerical control device described in patent document 1, only an abnormality caused by a change in the relationship between the machine coordinate system and the workpiece coordinate system is targeted, but the above-described workload increases as the number of types of abnormalities targeted increases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a numerical control device capable of suppressing the workload of a user and reducing the occurrence of an abnormality caused by an input operation.

In order to solve the above problems and achieve the object, the present invention provides a numerical control apparatus including: a machining control unit that executes a machining program to control the machine tool; an operation recording unit that records operation information indicating the content of an input operation to generate a 1 st operation history, and records operation information at the time of occurrence of an abnormality in the operation information in association with a machining program executed at the time of occurrence of the abnormality to generate a 2 nd operation history; and a notification unit configured to notify the message without causing the machining control unit to start execution of the machining program when it is determined that the current input operation is an abnormal operation using the 2 nd operation history when the input operation instructing execution of the machining program is received.

ADVANTAGEOUS EFFECTS OF INVENTION

The numerical control device according to the present invention can suppress the workload of the user and reduce the occurrence of an abnormality due to an input operation.
