Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numerical control device for machine tool equipment having comprehensive control functions including numerical control. More specifically, the present invention relates to a numerical control device with a computer function capable of stereoscopically viewing an assembly and parts to be replaced or repaired on a display of an attached display device and operating a displayed three-dimensional shape model. .

2. Description of the Related Art Generally, a machine tool device is equipped with a numerical controller (NC, Numerical Controller) for controlling the relative movement of a tool and a workpiece based on a numerical controller program. In recent years, with the progress of computer technology, many numerical control devices are equipped with a dedicated microcomputer and a numerical control device with a computer function (C
NC, Computerized Numerical Controller)
It is configured to be able to execute controls other than numerical control. As a result, the numerical control device can perform comprehensive management other than management related to one process such as data management, environment management, process management, and schedule management.

With respect to the replacement parts, even after the numerical control device was provided in the machine tool device, more advanced management became possible. The basic idea of a system that manages such replacement parts is to provide a sensor that detects the life of a part or the occurrence of a failure and an alarm that outputs an alarm sound or sound, and when there is a part to be replaced or repaired. To inform the worker.

Further, the numerical control device is located away from a display device having a graphics function including a display such as a cathode ray tube display (CRT, Cathode-Ray Tube Display) or a liquid crystal display (LCD, Liquid Crystal Display). Since it is equipped with a communication device that can send data to a computer in, it not only detects the wear and tear of parts and notifies it with an alarm sound, but also displays a comment on the display or a remote position. The computer in can be notified of the occurrence of the failure.

[0005]

Even in a numerical control device having a function of notifying the life and failure of parts by display,
Three-dimensional graphics representation of parts on the display is avoided. The reason is that creating drawing data of a three-dimensional shape model of a target part and storing it in a storage device requires a considerable amount of work in view of the number of parts, and is cost effective. There was little merit. However, if it is easy to display the three-dimensional shape of the part on the display,
For the user's worker and the maker's service personnel, even if the assembly has a relatively complicated configuration, the parts to be replaced or repaired can be visually understood.
It is guaranteed that the operability of the numerical control device will be improved. In particular, it is clear that even higher profits can be obtained if the parts forming the assembly can be displayed together with the assembly.

However, displaying a component imaged by a digital camera on the display requires a relatively small amount of man-hours and time to create the image data of the component. Therefore, the numerical controller uses the image data to identify the location of the failure. Is often displayed. However, this type of image data cannot be arbitrarily manipulated on the display such as, for example, separating a part from a three-dimensional shape model displayed on the display. Therefore, even if the entire image of the assembly is displayed on the display, the operator cannot see the parts themselves that need to be replaced, and it is difficult to understand how to remove the parts that need replacement. It's not easy. Even if an image of a single component is displayed on the display, it is easy for the operator to recall the actual location of the component on the machine tool machine or the numerical controller of the machine tool. I can't.

[0007] Similarly, even if the data of the three-dimensional shape model of the part is created by burdening a considerable amount of work and the part can be displayed three-dimensionally based on this data, simply the assembly or If only the parts are displayed, the worker
Without considerable knowledge, it is not possible to easily understand the arrangement and mounting state of the parts, so it is not possible to immediately make a judgment and replace the parts.

In view of the above problems, the present invention can more easily obtain the data of the three-dimensional shape model of the part and can operate the specific assembly displayed on the display device for each part. The main purpose is to provide a numerical control device for machine tool equipment. Some specific advantages of the numerical control device of the present invention will be described in detail in the detailed description of the invention.
