　この発明は数値制御（Numerical Control；以下ＮＣという）装置に係り、特に加工プログラムに用いる演算式の設定構成に関するものである。 The present invention relates to a numerical control (hereinafter referred to as NC) device, and more particularly to a setting configuration of an arithmetic expression used for a machining program.

　ＮＣ装置の加工プログラムに演算式を用いる技術が、特開昭６０－５１９０６号公報（特許文献１）に記されている。
　このＮＣ装置の加工プログラムに演算式を用いる技術は、設定表示部から加工プログラムとして演算式（Ｄi＝ＤjＳＩＮＤk）を入力すると、演算式処理部で、記憶部に記憶された「１０００」のデータを変数Ｄjに挿入するとともに、記憶部に記憶された「３０」のデータを変数Ｄkに挿入して演算を行う。そしてこの演算によりＤi＝５００の結果を得、この結果を出力部に出力して機械を動作させるものである。 Japanese Unexamined Patent Publication No. 60-51906 (Patent Document 1) describes a technique that uses an arithmetic expression for a machining program of an NC apparatus.

Is inserted into the variable D j and the data “30” stored in the storage unit is inserted into the variable D k to perform the calculation. Then, a result of D i = 500 is obtained by this calculation, and this result is output to the output unit to operate the machine.

Further, the arithmetic expression described in the machining program is described by combining variables, four arithmetic operators (+, −, *, /), arithmetic functions (SIN, COS, TAN) and the like. In this configuration, for example, when the same calculation is performed at a plurality of locations, it is necessary to describe the same calculation formula at each location.

And a memory to be stored.

　またこの発明に係るＮＣ装置は、前記変数編集設定機構を、変数として格納された演算式を前記メモリから取り出して、この演算式の一部またはすべてを書換えて、再び該メモリに格納するものとしたものである。 In the NC device according to the present invention, the variable editing setting mechanism may be configured to take out an arithmetic expression stored as a variable from the memory, rewrite a part or all of the arithmetic expression, and store the arithmetic expression in the memory again. It is a thing.

　またこの発明に係るＮＣ装置は、前記ＮＣ装置において、前記変数編集設定機構により変数として演算式が設定されたとき、この演算式を直ちに計算して解を算出する演算式解析機構と、変数として設定した演算式を、前記演算式解析機構によって算出した解とともに表示する変数表示機構とを備える構成としたものである。 Further, the NC device according to the present invention includes an arithmetic expression analyzing mechanism that immediately calculates an arithmetic expression when the arithmetic expression is set as a variable by the variable editing setting mechanism in the NC apparatus; A variable display mechanism for displaying the set arithmetic expression together with a solution calculated by the arithmetic expression analysis mechanism is provided.

In FIG. 2, 20 is an area for displaying a variable number, 21 is an area for displaying numerical data or an arithmetic expression stored in the variable, 22 is a variable number setting unit for a variable for storing the numerical data or the arithmetic expression, Reference numeral 23 denotes a setting unit for numerical values or arithmetic expressions stored in variables.

　キー入力装置１から入力したキーは変数番号設定部２２と数値または演算式の設定部２３に入る。つぎに、入力を確定するキーが押下されると、設定部２３に入力した数値または演算式は変数設定機構２を通り、設定部２２に入力された変数番号のデータ領域（メモリ３）に格納される。
　メモリ３に格納された演算式は、演算式解析機構４ａによって直ちに解が算出され、変数表示機構５で、変数番号と演算式の解２４と演算式２５とをならべた変数表示画面データ２６を作成し、表示装置６に表示する。
　メモリ３に格納されたデータが数値データのときは、変数表示機構５が数値データをもとに変数表示画面データ２８を作成し、表示装置６に表示する。 A key input from the key input device 1 enters a variable number setting unit 22 and a numerical value or arithmetic expression setting unit 23. Next, when the key for confirming the input is pressed, the numerical value or the arithmetic expression input to the setting unit 23 passes through the variable setting mechanism 2 and is stored in the data area (memory 3) of the variable number input to the setting unit 22. Is done.
The arithmetic expression stored in the memory 3 is immediately calculated by the arithmetic expression analysis mechanism 4a, and the variable display mechanism 5 displays the variable display screen data 26 including the variable number, the arithmetic expression solution 24, and the arithmetic expression 25. It is created and displayed on the display device 6.
When the data stored in the memory 3 is numerical data, the variable display mechanism 5 creates variable display screen data 28 based on the numerical data and displays it on the display device 6.

　次に図３を用いて変数置換機構８と演算式解析機構４bの動作を説明する。
　メモリ７に格納された加工プログラムは、Ｓｔｅｐ１で１ワード分が取り出される。図３の例では 　＃５００+３０.が相当する。
　次に、Ｓｔｅｐ２で変数の有無を調べる。変数は図３の例では＃５００ に相当し、＃の後ろに数値文字列が並ぶ部分を指す。
　Ｓｔｅｐ２において、変数が有りと判定されると、Ｓｔｅｐ３に進み、メモリ３に格納された変数のデータが演算式か数値データかを調べる。 Next, the operations of the variable substitution mechanism 8 and the arithmetic expression analysis mechanism 4b will be described with reference to FIG.
The machining program stored in the memory 7 is extracted for one word at Step 1. In the example of FIG. 3, # 500 + 30 corresponds.
Next, in Step 2, the presence / absence of a variable is checked. The variable corresponds to # 500 in the example of FIG. 3, and indicates a portion where numerical character strings are arranged after #.
If it is determined in Step 2 that there is a variable, the process proceeds to Step 3 to check whether the data of the variable stored in the memory 3 is an arithmetic expression or numerical data.

　メモリ３の変数に格納されたデータが演算式であればＳｔｅｐ４に進み、変数部分＃５００をメモリ３に格納された演算式 ［＃１００*ＣＯＳ［＃１０１］］ と置き換えて、［＃１００*ＣＯＳ［＃１０１］］+３０. の文字列を作成後、Ｓｔｅｐ５に進む。
　Ｓｔｅｐ３でメモリ３に格納された変数のデータが数値データと判定された時は、直接Ｓｔｅｐ５に進む。
　Ｓｔｅｐ５では［＃１００*ＣＯＳ［＃１０１］］+３０. の変数部分＃１００、＃１０１をそれぞれメモリ３から取り出した数値データ１０.、２０.に置き換えた後、Ｓｔｅｐ６で演算式を計算し、解 ３９．３９６９２を求める。 If the data stored in the variable of the memory 3 is an arithmetic expression, the process proceeds to Step 4, and the variable part # 500 is replaced with the arithmetic expression [# 100 * COS [# 101]] stored in the memory 3, and [# 100 * After creating a character string of COS [# 101]] + 30., Proceed to Step 5.
When it is determined in Step 3 that the variable data stored in the memory 3 is numeric data, the process proceeds directly to Step 5.
In Step 5, after replacing the variable parts # 100 and # 101 of [# 100 * COS [# 101]] + 30. With the numerical data 10. and 20. extracted from the memory 3, respectively, the arithmetic expression is calculated in Step 6. Find the solution 39.39692.

　Ｓｔｅｐ７では演算式の誤りを判定し、誤りがなければ１ワード分の解析が終了する。また、Ｓｔｅｐ７で誤りありと判定されたときはエラー処理を行う。
　なお、Ｓｔｅｐ１からＳｔｅｐ４は変数置換機構８の動作、Ｓｔｅｐ５からＳｔｅｐ７は演算式解析機構４ａおよび４ｂの動作である。
　以降、加工プログラム１ブロックに記述されたすべてのワードデータに対し、図３の動作フローの処理を繰り返すことで、加工プログラム１ブロック分の解析を行う。 In Step 7, an error in the arithmetic expression is determined. If there is no error, the analysis for one word is completed. If it is determined in Step 7 that there is an error, error processing is performed.
Note that Step 1 to Step 4 are operations of the variable substitution mechanism 8, and Step 5 to Step 7 are operations of the arithmetic expression analysis mechanisms 4a and 4b.
Thereafter, the processing for one block of the machining program is analyzed by repeating the operation flow of FIG. 3 for all the word data described in the machining program 1 block.

　この実施例によれば、演算式を変数に設定でき、加工プログラム中の変数は、変数に設定した演算式に置換した後で数式解析を行うように構成したので、加工プログラムの演算式は変数１つで記述できるようになり、プログラム作成作業が軽減できるという効果がある。 According to this embodiment, the arithmetic expression can be set as a variable, and the variable in the machining program is configured to perform mathematical analysis after replacing the arithmetic expression set in the variable. It is possible to describe with one, and there is an effect that the program creation work can be reduced.

　また変数に演算式を設定できるように構成し、かつその演算式をただちに計算して解を算出し、演算式とその解を表示するように構成したので、演算式の計算結果が即座に確認できるという効果がある。 In addition, it is configured so that an arithmetic expression can be set for a variable, and the arithmetic expression is calculated immediately to calculate a solution, and the arithmetic expression and the solution are displayed, so the calculation result of the arithmetic expression can be checked immediately. There is an effect that can be done.

　更にまた、演算式を変数に設定でき、設定した演算式を書き換えができように構成し、加工プログラム中の変数は、変数に設定した演算式に置換した後で数式解析を行うように構成したので、１つ、もしくは複数の加工プログラムに同じ演算式を用いた場合においても、変数に設定した演算式を変更するだけで、すべての加工プログラムの演算式が変更できるようになり、プログラムの演算式変更作業が軽減できるという効果がある。 Furthermore, the calculation formula can be set as a variable, and the set calculation formula can be rewritten. The variable in the machining program is configured to perform mathematical analysis after replacing the calculation formula set in the variable. Therefore, even when the same arithmetic expression is used for one or more machining programs, it is possible to change the arithmetic expressions for all machining programs by simply changing the arithmetic expression set for the variable. There is an effect that the expression change work can be reduced.
