Abstract

PURPOSE:To raise operability of an operator in a job site by providing an input data discriminating part on a control part, and also providing an operational expression processing part on an operating part. CONSTITUTION:When an operational expression is inputted from a set display part 1, whether it is a numerical value or an operation is discriminated by an input data discriminating part 2A, and an operation processing is started. In this state, when a numerical value is inputted from the display part 1, this numerical data is inputted to an operation processing part 3A, and an operation is executed. A necessary numerical value is inputted and an operation is executed, and when it is completed, a result of the operation is stored in a storage part 4, outputted from an output part 5, and a machine 6 is controlled. In this way, when a necessary value is given to the operational expression and the operation, a necessary operation is executed, and its result is outputted to the machine 6, therefore, an operating time to a numerical control device in a job site is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a 5K numerical control device that can provide input data using an arithmetic expression.

[Prior art]

A conventional numerical control device C (hereinafter referred to as an NC device) of this type will be explained with reference to the Guts diagram shown in FIG. In this figure, 1 is a setting display section, 2 is a control section, 3 is a calculation section, 4 is a storage section, and 5 is an output section, which together constitute the NC device. 6 indicates a machine to be controlled.

Next, to briefly explain the operation, a program written in a high-level language such as the RASIC language is input from the keyboard of the setting display section 1 equipped with a CRT.

The control unit 2 causes the calculation unit 3 to perform necessary numerical calculations based on the input program, stores the resulting data in the storage unit 4, and sequentially supplies it to the machine 6 via the output unit 5 to perform control according to the program. let This control is performed for each axis of the machine 6.

In such a conventional device, only numerical values can be input from the setting display section 1. For example, "X-1000, Y=5
00J's 5VC. Therefore, for example, the length DJ of the hypotenuse and the angle Dk formed between the hypotenuse and the base as shown in Fig. 2.
When inputting the length of the vertical side from and, the sentence ``to'', the length of this vertical side.

The above calculations were performed using a separate desktop calculator, and the resulting vertical length had to be entered, which had the drawback of extremely poor operability.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks, and in order to allow input data to be given using an arithmetic expression, a manual data discriminator was provided in the control section, and the rA
An arithmetic expression processing section is provided in the arithmetic section to enable the calculation.

[Embodiments of the invention]

FIG. 3 is a block diagram showing one embodiment of the present invention.

゛In this figure, 2 are a manual data discriminator provided in the control section 2Vc, and 3A is a tl arithmetic expression processing section provided in the arithmetic section 3.

Next, the operation of the embodiment shown in FIG. 3 will be explained with reference to the 7 μm chart shown in FIG. In addition, ① to ② in FIG. 4 indicate each step. Hereinafter, FIG. 2 will be explained using an input example r (.

First, the arithmetic expression r r)l=Dt S I N D J k is inputted from the setting display section 1 using BASIC headings or the like. The input/take discriminator 2A discriminates whether the input is a numerical value or an operation. In the above case, since the input is an arithmetic expression and not a numerical value, the process proceeds to step (3) and arithmetic processing is started.

In this state, next go to setting display section 1.

Enter =1000. This time, since the input is a numerical value, proceed to step ■. And since the calculation is in progress, = 10
The data of 00 is taken in by the arithmetic expression processing section 3AK.Next, when the data of Dk=30 is input 4, since this is also a numerical value, it is taken in by the arithmetic expression processing section 3AVc, and the calculation is performed. D, ==5 (10 pieces are stored. When the operation is completed, ■
,D, =: 5 (The numerical value of 10 enters the buffer memory and is output from the output section 5■.

In this way, by providing the arithmetic expression and the numerical values necessary for the operation, the desired operation is performed 4, and the result is output to the machine 6':! −
It will be done.

〔Effect of the invention〕

As explained in detail above, in this invention, the control section is provided with an input data discrimination section, and the calculation section is provided with an arithmetic expression processing section, so that input data can be input from the setting display section in the form of an arithmetic expression. , it is no longer necessary to manually perform calculations on a separate desktop calculator as in the past.
This has the advantage of significantly improving operability for on-site operators.
