Abstract

PURPOSE:To reduce the occurring probability of input mistakes by applying a touch input method for programs through a CRT screen. CONSTITUTION:When a touch is given to a prescribed position of a display screen where a touch sensor 3 is set, a touch sensor control part 2 decides the coordinates on the screen. Then a main CPU 4 decides the information on said coordinates as prescribed based on a program included in a memory 1. The CPU 4 carries out each processing in response to a part having a finger touch. Thus an operator can have input of program commands of the working order and the tool shift based on the drawing of a working object, etc., with use of the graphics most suited to the input after recognizing visually many types of picture information at a time in comparison with a key operation method where similar keys are arranged in a small space.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention converts program instructions related to machining order and tool/jig movement control into numerical information within a device, and electronically controls positioning and various continuous operations using pulse signals. The present invention relates to a numerical control device that performs control, and more specifically, it relates to a numerical control processing device that performs input by touching a screen without relying on manual keys.

[Prior Art] An overview of the hardware configuration of a conventional numerically controlled machining device will be described with reference to FIG.

In Figure 2, (1) is the memory, (4) is the main CP

Here, the memory (1) stores various processing programs and various data, and the main CPU (4) performs input processing of the cannibal program, calculation of each incremental movement amount in the three axis directions, various correction calculations, and interpolation processing. , communicate with the operator, display settings, etc.

The I10 interface (5) is an interface card for a paper tape reader puncher, 510 (Miriyal I10). Programmable controller PC (6)
performs input/output processing with the machine operation panel and sequence processing such as MST.

The display key (7) controls the setting display function for communication with the operator.

Next, the operation will be explained with reference to FIG.

First, a modified program is created, and then the modified program processing operations shown in (8) are performed, in which one block of the modified program is read and the information is converted to an internal format.

Next, incremental value calculations and correction calculations are performed in the process shown in (9), and the internal format obtained in (8) is input, and the incremental movement amount of one block is calculated in the X, Y, and Zo three-axis directions by ΔX, ΔY. ,Δ
Z, and further perform correction calculations related to specific conditions such as tool diameter and tool length.

Furthermore, in (9), updating processing of the coordinate axes inside the device hardware is also performed.

Next, interpolation processing is performed in the process shown in (10). Here, ΔX obtained in process (9).

Interpolation processing is performed based on ΔY, ΔZ, etc. That is, the minute movement amount in the minute time ΔT is determined as ΔX, ΔY, and ΔZ in the three axial directions, respectively.

Next, processing related to setting/display processing is performed in the process shown in (11). In this process, various data in the numerical control device are displayed on the CRT, and various setting processes by the operator are also controlled.

Next, servo processing is performed in the process shown in (12). Here, ΔX obtained by interpolation processing (10).

The servo processing is performed by further converting ΔY and ΔZ into subdivided movement amounts of minute time Δt.

In the process shown in (13), PC processing, that is, input/output to the machine operation panel such as switch input and lamp output is performed. Also, in this process, each function such as M, S, and T is executed and the surroundings of the processing machine are controlled. In the past, machining programs were created one block at a time using EIA code, but recently, numerically controlled machining equipment that automatically creates programs interactively from the keyboard, as shown in Figure 4, has been used. are also appearing.

[Problems to be Solved by the Invention] In recent numerically controlled machining equipment, the creation of a machining program is done by checking the display on the screen and visually by the operator, and manually inputting the program using keys using fingers. Input methods are being put into practical use, but because the screen and keys are far apart from each other, input errors are likely to occur due to operator fatigue, misreading lines or characters, or optical illusions. There was a problem.

Furthermore, since the image plane and the key positions are far apart, there is a problem in that the operator's input judgment and visual recognition operations take time and fatigue accumulates.

The present invention has been made to solve the above-mentioned problems, and in short, by configuring the image plane and the keys on the same plane, the image to be viewed and the area to be manually operated corresponding to the visibility can be distanced. The purpose is to provide a numerically controlled machining device that eliminates input errors and has good manual workability.

[Means for Solving the Problems] The numerically controlled processing apparatus according to the present invention is configured with a touch sensor provided on a display screen and means for receiving input by touching the screen.

[Function] The touch sensor on the display screen in the present invention brings the image information position when the operator makes an input operation, the image information position of the input result, and the input position into proximity by the action of directly touching the image display surface with a finger. By doing so, the probability of occurrence of misidentification, misjudgment, or incorrect input action related to the operator's input action is reduced.

[Example] An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, (1) is a memory containing a program for processing human power of the touch sensor, (2) is a touch sensor control unit, and (3) is a touch sensor body.

The operation of one embodiment of the present invention will be explained based on FIG.

When a predetermined position on the display screen on which the touch sensor (3) is placed is touched, for example, with a finger, the touch sensor control unit (2) determines the coordinates on the screen and the main CPU stores this information in the memory (1). A predetermined determination is made based on the program in use, and each process corresponding to the part touched by the finger is executed.

In one embodiment as described above, the operator can perform input while viewing a large amount of image information at the same time and using the most appropriate graph for input, compared to key operations where similar keys are concentrated in a small space. Become.

[Effects of the Invention] As described above, according to the numerically controlled processing device according to the present invention,
For program input, keys are centrally arranged in a small space,
In order to form a signal with a small number of key combinations, it visually checks the image display information to determine which key to operate.
After that, the operator's eyes shift to the keyboard, search for a key, and press it repeatedly, which increases the possibility of erroneous presses due to the interference of illusions and the interference of illusions, resulting in a completely different signal being input if the operator presses the next key by mistake. Instead of the conventional manual key system, we use a touch-type input system that makes decisions on the screen based on a large amount of visual information and then embeds the input, which has the effect of reducing the probability of input errors caused by illusions caused by fatigue or other factors. It is.
