無接觸型刀具監(jiān)控系統(tǒng)Non-Contact Tool Monitoring
該系統(tǒng)是通過PWM或VM傳感器對加工過程中軸向驅(qū)動電流或震動能量的變化實施監(jiān)測，并將監(jiān)測值同已知設(shè)定模型進行對比的方式實現(xiàn)監(jiān)控功能。該系統(tǒng)適用于標(biāo)準電機設(shè)備，交流伺服電極設(shè)備，變頻電機和直流電機設(shè)備監(jiān)控，以及對軸向，夾具，工件或刀具的震動監(jiān)測。
The Techna-Check® is a Tool Monitoring system designed to use the PWM series power transducers or the VM series vibration transducers to determine if there is a Broken, Dull or Missing tool. The PWM measures true power on a machine spindle or axis motor. It can be used on standard motors, AC servo motors,variable frequency drives and DC drives. The VM uses an accelerometer to monitor for excess vibrations on spindles, fixtures, parts or tooling.

Idle Power Monitoring
Detection of idle power faults can alert you to broken belts or bad bearings.
磨損調(diào)整：系統(tǒng)”學(xué)入“功能可即時檢測磨損程度，同時進行相應(yīng)修正和調(diào)整。
Adjusts to Tool Grind
The built-in “l(fā)earn” function enables the system to compensate for differences in tool grind, improving the monitoring while reducing nuisance faults.
關(guān)鍵優(yōu)勢
有效運行：破損，無加工監(jiān)控能保障設(shè)備有效運行。
Proper Machining
The detection of missing or broken tools helps insure that the proper machining is being performed.
加工保證：狀態(tài)的即時監(jiān)控保障加工工件合格率。
Improved Finish and Tolerance
Detection of tool wear and damage can help improve surface finish and tolerances.
機械保護：通過監(jiān)控，可避免由于故障引起的主軸等機械破壞性的損壞。
Protection of Spindle and Feed Mechanism
By detecting catastrophic tool failure, TECHNA-CHECK can prevent serious damage to your head and feed mechanisms, not just at the station being monitored, but at down-stream stations where “chain reaction” effects can occur.
撞擊保護：避免由于斷裂引起的主軸，軸向類撞擊。
Crash Protection
Preventing crashes & tool breakage can help eliminate costly damage to your spindle.
斷裂保護：避免斷裂導(dǎo)致的不良工件產(chǎn)生。
Broken Tool Protection
Catching tool breaks minimizes scrap while guaranteeing perfect parts.
磨損保護：通過監(jiān)控，可有效利用化其加工壽命。
Worn Tool Protection
Measuring for worn tools helps you maximize your tool life.
化壽命：監(jiān)控可化利用較昂貴，提高生產(chǎn)成本效益。
Maximized Tool Life
By detecting for tool wear and damage, expensive tooling can be changed before the damage gets too severe. This detection also reduces dependence on hit or miss part counting schemes.

工作原理 Principle of Operation
系統(tǒng)通過接受由設(shè)備發(fā)出的24DC或PROFIBUS信號啟動監(jiān)控功能，取決于被監(jiān)控對象，系統(tǒng)多可學(xué)入128個獨立的加工過程，監(jiān)控刀具號的選擇由設(shè)備通過M代碼/宏程序代碼或PROFIBUS信號以24DC二進制代碼的形式將指令傳至監(jiān)控系統(tǒng)。
The TECHNA-CHECK® interfaces to the machine control and is given a 24vdc or Profibus signal from the machine to tell the unit when to start monitoring. Depending on the system being used it will learn between 1-128 different cutting profiles. The tool selection is done via 24vdc binary inputs which are typically given using M-codes/ custom macro or by using Profibus.
監(jiān)控系統(tǒng)接到啟動指令后，即開始監(jiān)控功能，測量并確定相應(yīng)驅(qū)動軸空運行能量消耗，以此建立空載模型，同時依據(jù)此模型設(shè)定高低限位值以判斷設(shè)備是否存在皮帶斷裂或軸承磨損情況。
Once the unit has been told to monitor, the system will measure the power that is used just to turn the spindle; this is labeled as the idle consumption within the image to the right. High and low limits can be set for the idle power to determine if a belt has broken or bearings are going bad in the spindle.
在監(jiān)控系統(tǒng)學(xué)入切削過程的能量消耗狀態(tài)后（同時建立參考模型），當(dāng)?shù)谰吣p時，其加工過程將消耗更多能量，當(dāng)?shù)毒邤嗔褧r，能量消耗會短暫出現(xiàn)跳動峰值，如果在無刀具的狀態(tài)下進行加工，其消耗的能量將至零。在以上所論狀態(tài)下，Techna-check系統(tǒng)都會給出故障信息，并及時停止設(shè)備運轉(zhuǎn)。
The unit then learns the amount of power it takes to cut the material (labeled as measurement within the image to the right). As a tool becomes blunt (dull) the tool will begin to require more power to complete a machining cycle. When the tool breaks a short energy peak or spike is created and if no tool is present or the part has already been machined, the power consumption drops back to zero. If any of these situations occurs the TECHNA-CHECK will output a fault which will immediately stop the machine.
另外，系統(tǒng)可以監(jiān)控“接觸點”，該功能適合應(yīng)用于研磨和平衡設(shè)備中，在刀具向加工工件運行過程中可以高速行進，監(jiān)控系統(tǒng)在刀具開始接觸到工件時發(fā)出指令，令設(shè)備控制刀具以慢速運行。
Additionally the TECHNA-CHECK can monitor “Touch Point”. This is used in grinding and balancing applications where the tool is fed into the part at a rapid rate. As soon as a rise above idle power is detected the system outputs a signal telling the machine control to slow the feed rate of the machine.
