Techna-check 理想化的监控系统，令您的设备更稳定，更耐用
Ideal For Monitoring Tools On Single Spindle Heads. .
无接触型刀具监控系统Non-Contact Tool Monitoring
该系统是通过PWM或VM传感器对加工过程中轴向驱动电流或震动能量的变化实施监测，并将监测值同已知设定模型进行对比的方式实现监控功能。该系统适用于标准电机设备，交流伺服电极设备，变频电机和直流电机设备监控，以及对轴向，夹具，工件或刀具的震动监测。
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.

工作原理 Principle of Operation
系统通过接受由设备发出的24DC或PROFIBUS信号启动监控功能，取决于被监控对象，系统多可学入128个独立的加工过程，监控刀具号的选择由设备通过M代码/宏程序代码或PROFIBUS信号以24DC二进制代码的形式将指令传至监控系统。
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.
监控系统接到启动指令后，即开始监控功能，测量并确定相应驱动轴空运行能量消耗，以此建立空载模型，同时依据此模型设定高低限位值以判断设备是否存在皮带断裂或轴承磨损情况。
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.
在监控系统学入切削过程的能量消耗状态后（同时建立参考模型），当道具磨损时，其加工过程将消耗更多能量，当刀具断裂时，能量消耗会短暂出现跳动峰值，如果在无刀具的状态下进行加工，其消耗的能量将至零。在以上所论状态下，Techna-check系统都会给出故障信息，并及时停止设备运转。
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，系统可以监控“接触点”，该功能适合应用于研磨和平衡设备中，在刀具向加工工件运行过程中可以高速行进，监控系统在刀具开始接触到工件时发出指令，令设备控制刀具以慢速运行。
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.
