Application of sensor technology in Precision machining
With the development of the times, more and more intelligent, this is no longer a big topic, we have also introduced in the traditional processing industry such as Precision machining, There are also many modern high-tech applications. Today we will introduce the very popular sensor technology. It can be said that more and more industries have begun to use sensor technology. In fact, we have many in our lives, but we dont have Just care, the automatic induction door is a very common example. The purpose of sensory detection in the machining and cutting process is to optimize the productivity of the cutting process, the manufacturing cost, or the (metal) material removal rate. The targets detected by the cutting process sensor include the cutting force and its change during the cutting process, the chattering of the cutting process, the contact between the tool and the workpiece, the state of the chip during cutting, and the identification of the cutting process.The most important sensor parameters are cutting force and cutting. Process vibration, acoustic emission during cutting, power of motor during cutting, etc. For the operation of the machine tool, the main sensor detection targets are drive system, bearing and slewing system, temperature monitoring and control, and safety, etc., and its sensor parameters include machine tool downtime, surface roughness and processing of the workpiece Accuracy, power, machine state and cooling lubricant flow rate, etc. The sensor technology in the process of the workpiece, compared with the tool and machine tool process monitoring technology, the process monitoring of the workpiece is the earliest and most researched and applied. Most of them aim at quality control of workpiece processing. Since the 1980s, the requirements for workpiece identification and workpiece posture monitoring have also been mentioned on the agenda. Roughly speaking, process identification is to identify whether the machining process performed is a work (zero) part processing requirement; workpiece identification is to identify whether the workpiece or blank to be processed into the machine tool is the workpiece or blank required to be processed, while also It is required to identify whether the posture installed by the workpiece is the posture required by the process regulations. In addition, workpiece recognition and workpiece installation monitoring can also be used to sense the processing margin and surface defects of the blank or workpiece to be processed. Many sensors will be adopted or developed to complete these recognition and monitoring, such as TV or CCD-based machine vision sensors, laser surface roughness sensing system, etc. Machine tool detection sensor. The cutting and grinding process is an important material removal process. The cutter and the grinding wheel are worn to a certain limit (determined according to the blunt grinding standard) or damaged (general term for broken, chipped, burned, plastic or reel), which makes them lose their cutting (grinding ability or unable to guarantee machining accuracy and machining surface When it is complete, it is called tool/grinding wheel failure. Industry statistics prove that tool failure is the primary cause of machine tool downtime, and the downtime caused by it accounts for one-fifth to one-third of the total downtime of NC machine tools. No. Finally, the most important point of sensor technology for Precision machining is to reduce the accident rate. We should be very clear that the machine tool may also cause equipment or personal safety accidents or even major accidents during machining. Now on high-end machine tools Equipped with a tool detection sensor can effectively prevent such events. In fact, many customers are saying that pretending the sensor will cost a lot of money. In fact, if the smart boss who can calculate the account will definitely find out, in fact, this technology can greatly improve production efficiency. Reduce waste and cost, especially with high safety. article is organized and published by Quality parts:https://www.professionalmanufacturing.com/shownews.asp?id=116
