In addition, as mentioned above, various calculations are performed before creating the machining program, and are also calculated using predetermined calculation commands that cause various calculations to be performed during the program or calculation commands that use a predetermined grammar. 1.Sequentially machine tools as above (
8) is driven.

As described above, conventional NC machine tools have the disadvantage that various calculations can only be performed through the machine program f.

The object of the present invention is to provide an NC machine tool having the function of performing various calculations through the above-described machine program (r) and also by operations other than machine program commands.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts, so the explanation will be omitted. (9) is a character display device (hereinafter referred to as CRT);
This CRT (9) performs calculations in the calculation unit (3) when various calculation requests are made from the operation unit (5), and the results are sent to the CRT.
It is displayed on RT (9) and stored in VcfI storage section (4).

Further, this device can be instructed using the above calculation results using a predetermined program, and can also perform further calculations based on the calculation results.

FIG. 8 shows in detail the operating section (5) and the CRT (9) with the VC provided. SUB Ghee, M

), a sign and each numeric key from 0 to 9.

Next, with reference to FIG. 3, calculation operations will be explained using examples of addition and multiplication including sine operations.

First, in the case of addition, (1) Select the calculation request key (!-) on the operation panel (5) and press the key in to display D (which means a variable) on the CRT (9).
Iυ is fixedly displayed.

(2) Numerical key The numerical value is displayed in the variable number α by keying in the cormorant. This numerical value is used to store the calculation result obtained in the following explanation in a predetermined location of the storage section. Note that in the case of zero, it is not stored in the storage section, and only the calculation result is displayed on the CRT (9) in the ANS section αQVc.

(3) Key in the numerical value you want to calculate using the numerical keys (goods), and the number M (13) will be displayed.At this time, key in the signs such as positive and negative as appropriate.

(4) By selecting and keying in the ADD key of the calculation content selection key ψp, an addition symbol α◆ tube is displayed.

(5) Numeric key M VCL When you key in an additional value, that value αυ will be displayed.

(6) Repeat steps (3) to (5) above as many times as desired.

(7) Calculation is performed by selecting and keying in the = key of the calculation content selection key Qlil), and the result is
It is output and displayed in the S section q→, and furthermore, when the variable number @ is other than zero, it is stored in a predetermined storage section.

Next, in the case of multiplication including sine operation, select (1) operation request key and key in, CRT ((1)
D (a), which means a variable, is fixedly displayed.

(2) When the numeric key @ is pressed, a numeric value is displayed in the variable number CI), and the calculation result is stored in a predetermined location in the storage section according to this numeric value.

(3) Key in the numerical value you want to calculate using the numeric key -, and the numerical value (A) will be displayed. (4) Select the MPY key of calculation content selection key 6υ and key in to display the multiplication symbol (To). .

(5) By selecting and keying in the SUN key of the operation content selection key φη, the sine operation symbol (c) is displayed.
