Abstract

A data input device for a numerical control apparatus enables the input of data in the form of an equation. An equation input through a key input means (KB) is stored in a temporary input buffer (BUF). When a calculation command is input from the key input means (KB), an equation calculation means (ART) operates on the equation stored in the temporary input buffer (BUF) and then stores the result in the temporary input buffer (BUF), replacing the original equation with the result of the calculation. The result of the calculation is stored in a predetermined memory area in a data storage memory means (MEM) by a data input processing means (DIN) when an input command is input from the key input means (KB) after the calculation command.

Reference numeral 19 denotes a servo amplifier, and reference numeral 20 denotes a motor. In the case of the NC command program, when given in the form of command tape 7, it is stored in external memory 8 via tape reader 6, and when given and stored, it is stored in external memory 8. Directly from the memory, each is read and decoded by the micro computer 1, and the operation information is created. The normal NC operation is based on this operation information.] The axis control circuit 18 is controlled, and the rotation of the motor 20 is controlled by the servo amplifier 19. Such an operation is well known from the past.

FIG. 4 is a flowchart showing an example of a software configuration of the data input device of this embodiment. In an NC unit, to save storage space, one byte parameter contains two or more data.For example, the upper 4 bits and the lower 4 bits are separated. It is used for the purpose. In such a case, if it is desired to change the lower 4 bits of data, for example, ³ from the upper 4 bits of data, for example, from ⁹ to 7, a conventional NC unit may be used. As shown below, the z-lamellar numbers are 40 6 1, =. I was typing.

4061 = 115-··· (1) However, this operation] ?, the parameter number 4061, =. The changed value of the upper 4 bits 7 as follows: , Multiplication symbol *, 16, Addition symbol +, and the lower 4 bits of value ³ are easier to enter in this order.

4061 = 7 * 16 + 3 (2) Taking such a case as an example] 9, the data input operation of this embodiment will be described.

First, using the character input key 9d of the keyboard 9 to sequentially input the character string of the above expression ( ² ) from the beginning of the character string, the microphone computer 1 receives the input. The characters are sequentially stored in the temporary input buffer area 4a of the RAM 4 (S1 to S3), and the input characters are stored in a predetermined area of the video RAM 15 via the data driver 14, for example, Write in the area corresponding to the lower corner of the screen (S4). As is well known, the content of the video RAM 15 is determined by the scanning address of the CRT controller 11]? Is converted into display dot data by the character generator ROM 16 and input to the display unit 17 as a video signal. Therefore, characters entered from the keyboard 9 are displayed in the lower left corner of the CRT screen. Then, when the calculation command key 9b of the keyboard 9 is pressed, the micro computer 1 determines that the input key code is the calculation command key code. (S6), and calculates a mathematical expression in the temporary human resource area 4a, creates a character string in which the mathematical expression is replaced by the calculated numerical value, and stores the character string in the RAM.

Also, the rewritten ^ is temporarily entered. The contents of the buffer 4a are transferred to the video RAM 15, and the previous contents are changed or stored together with the previous contents (CS10). Therefore, in the case of the above (formula), the following contents are displayed on the screen of the display unit 17.

4061 = 115 (3) If there is an error in the formula, the error is displayed (S8. S11).

Next, the operator confirms the above display and

ΟΜΡΙ 115 is stored in the corresponding byte (S12). After completion of the data input processing of the call, also click Li § contents of the temporary input bus Tsu off § area ⁴ a one o'clock both Ru written in the video HAM 15 the phrase Li Asuru the contents of the input bus Tsu off § area And erase the display (S'14). If an error occurs during the data input process of step S12, an error is displayed (

S13) o If another type of command key is pressed, processing branches depending on the pressed key, and the contents of the temporary input buffer area 4a are decoded by each processing routine. Then, necessary processing is performed (S15). After entering the string, if immediately press the Enter command key ⁹ a without pressing the calculation command key ⁹ b, in the present embodiment, not cracking computing row

(S12).
