対して、工具情報を読み出す、その際Ｋ。To read the tool information for the tool specified for each machining part in the machine program, use K.
各工具毎に設定さｉｔている使用回数及び使用時間によ
る各工具のＶｔ命を判定し、交換が必要であｒしば、他
の代替工具を使用して加工を継続する。The Vt life of each tool is determined based on the number of times of use and the time of use set for each tool, and if replacement is necessary, machining is continued using another alternative tool.
従来の数値制御装置は以上のように溝成され−Ｃいるの
で、使用回数及び使用時間での寿命管理は。Since conventional numerical control devices are structured as described above, their lifespan can be managed based on the number of times they are used and the length of time they are used.
標準的な設定となり、各チップ毎のバラツキが補完でき
なく、又、工具交換時の判定では不充分であるなどの問
題点があった。There were problems such as standard settings, which could not compensate for variations in each chip, and insufficient judgment when changing tools.
この発明は以上のような問題点を解消するためになされ
たもので、各加工状態から工具の状態を監視し、かつ、
各加工途中であっても、その加工を中断し新規工具への
交換を行なうことを目的とする。This invention was made to solve the above problems, and it monitors the tool condition from each machining condition, and
The purpose of this tool is to interrupt the machining process and replace it with a new tool even if it is in the middle of machining.
この発明に係る数値制御装置は、工具の状態を把握する
為に、主軸等の負荷状態を入力するＩ／Ｆを用意し、負
荷を監視するとともに、補間処理中にも、工具交換をす
る手段を設けたものである。The numerical control device according to the present invention is provided with an I/F for inputting the load state of the spindle, etc., in order to grasp the state of the tool, and means for monitoring the load and changing the tool even during interpolation processing. It has been established.
この発明における工具の交換は、工具の状態をリアルタ
イムで監視が可能となり、工具マモウ等による不良加工
を少なく出来る。In the tool exchange according to the present invention, the condition of the tool can be monitored in real time, and defective machining due to tool misalignment can be reduced.
以下、この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図において、（１）は加ニブログラムの解析等を行
うＣＰＵ、＋２１は加ニブログラム等を記憶するメモＩ
Ｊ、＋３１は各工具単位の情報を記憶するメモリ。In Fig. 1, (1) is a CPU that analyzes the Kani program, etc., and +21 is a memory I that stores the Kani program, etc.
J, +31 is a memory that stores information for each tool.
（４）は状態表示用のＣＲＴ、＋５１は軸サーボ等との
外部Ｉ／Ｆ、＋６１は負荷状態を検知する為のＩ／Ｆで
ある。(4) is a CRT for status display, +51 is an external I/F with an axis servo, etc., and +61 is an I/F for detecting the load status.
又、第２図は 本発明における簡略なフローを示す。Moreover, FIG. 2 shows a simple flow in the present invention.
上記のよう例構成された数値制御装置においては、記憶
している加ニブログラムを読み出し、解析し、「抽サー
ボ等へ、補間出力を出力する。又。In the numerical control device configured as described above, the stored Kaniprogram is read out, analyzed, and an interpolated output is output to the extraction servo, etc.
負荷状態から、各工具単位で記憶されている情報から、
警報範囲と異常範囲を判定する。From the load condition and the information stored for each tool,
Determine the alarm range and abnormal range.
加ニブログラムの各ブロック解析の直前では。Immediately before each block analysis of the Canadian program.
警報か否かの判定を行い、警報状態であれば２代替工具
をサーチして、工具交換を行ない、を報状態を解除して
、加工を継続する。又、ブロックの各補間処理前には、
異常状態か否かの判別を行ない、異常状態であれば１代
替工具をサーチし、工具交換を行ない、そのブロックの
先頭から、加工を再開する。It is determined whether there is an alarm or not, and if it is in the alarm state, two alternative tools are searched, the tool is replaced, the alarm state is canceled, and machining is continued. Also, before each block interpolation process,
It is determined whether or not there is an abnormal state, and if it is, one alternative tool is searched, the tool is replaced, and machining is restarted from the beginning of the block.
なお、上記実施例では、主軸等の負荷情況を監視して行
なったが他の計測手段により、工具のマモウ情況を監視
することも可能である。In the above embodiment, the load condition of the spindle etc. was monitored, but it is also possible to monitor the load condition of the tool by using other measuring means.
本発明は１以上のように構成されているので。 Since the present invention is configured in one or more ways.
工具のマモウ状態をリアルタイムで監視すること罠より
、より確実な寿命管理が得られる効果がある。Monitoring the condition of tools in real time has the effect of providing more reliable life management than traditional methods.
