K4) of · of 67 × 10-12W/(cm2. Graph 1 temperature field is online basis of block diagram of the system that monitor this error hedge - Bo ear thises graceful constant is mensurable, the temperature of the object is higher, radiation strength is greater. The temperature that should know an object only reachs his to blast off rate, with respect to the radiation intensity that can measure an object place to blast off. If the graph is shown 1 times, use infra-red the temperature field that measures Wen Yi to monitor work, the method that this device uses fast and mobile sensor undertakes those who realize temperature field fast scanning comes to divide evenly to its workpiece monitor. The double tool carrier that uses lathe will pass feeling head installation to be on a tool carrier, when measuring, infra-red pass feeling head to follow tool carrier divide evenly fast shift, signal of its workpiece temperature puts evacuation to collect card into data via carry in. According to the rate with the length of workpiece, floating tool carrier, reach the change in the temperature inside cycle of a scanning, build a coordinate, rise workpiece length and temperature change correspondence, undertake successive scanning to turning workpiece suppose, every time sweep time is 5s, got the work with 5s clearance so the temperature of each positions, handle software with the computer but the temperature field that draw gives this work. Analysed additionally infra-red measure lukewarm precision and dependability, it suffers the effect of a lot of elements, if atmosphere is absorbed, limits of area of wavelengh of heat radiation of equipment of adjacent of rate of radiate of coefficient of setting of radiate of air dust and suspension particle, sun's rays, wind- driven, test, distance, object, photograph, job and instantaneous angle of visual field. From above a few respects were analysed right infra-red the effect that measures lukewarm precision. This literary grace is used infra-red measure Wen Yi to be in with respect to turning workpiece the temperature field below treatment status undertakes monitoring. From the point of the result that monitor: Use infra-red measuring Wen Yi to undertake monitoring to the temperature of turning workpiece is feasible and effective; It can reflect the change of workpiece temperature field in real time quickly, its precision can amount to ± 3 ℃ , satisfy the requirement that we monitor completely.
