With the development of the times and the increasing intelligence, this is no longer a big topic. Previously, we also introduced that in traditional processing industries such as precision machining, there are many modern high-tech applications. Today, we will introduce the very popular sensor technology. It can be said that more and more industry fields have begun to use sensor technology, and in fact, there are many in our lives, It's just that we didn't pay attention, automatic sensing doors are a very common phenomenon. The purpose of sensing detection in mechanical machining cutting process is to optimize the productivity, manufacturing cost, or material removal rate of the cutting process. The targets of the cutting process sensor detection include the cutting force and its changes during the cutting process, chattering during the cutting process, contact between the tool and the workpiece, the state of the chip during cutting, and identification of the cutting process. Important sensing parameters include cutting force, cutting process vibration, cutting process sound emission, and the power of the cutting process motor. For the operation of machine tools, the main sensor detection targets include the driving system, bearing and rotation system, temperature monitoring and control, and safety. The sensor parameters include the downtime of the machine tool due to faults, surface roughness and machining accuracy of the machined parts, power, machine state, and flow rate of cooling and lubricating fluid.
Compared with the process monitoring technology of cutting tools and machine tools, the sensor technology in the process of workpiece monitoring has been studied and applied earlier and more frequently. Most of them aim to control the quality of workpiece processing. Since the 1980s, the requirements for workpiece recognition and workpiece installation pose monitoring have also been put on the agenda. Roughly speaking, process identification is used to identify whether the processing process being executed is a required process for processing workpieces (parts); Workpiece recognition is the process of identifying whether the workpiece or blank sent to the machine tool for processing is a required workpiece or blank, and also requires identifying whether the position of the workpiece installation is the position required by the process regulations. In addition, workpiece recognition and workpiece installation monitoring can also be used to sense the machining allowance and surface defects of the workpiece or workpiece to be processed. Many sensors will be used or developed to complete these recognition and monitoring, such as machine vision sensors based on TV or CCD, laser surface roughness sensing systems, etc.
Detection sensor for machine tool tools. Cutting and grinding processes are important material removal processes. The cutting tool and grinding wheel are worn to a certain limit (judged according to the blunting standard) or damaged (collectively referred to as damaged, chipped, burned, plastic deformation, or rolled knives), Make them lose their cut When the grinding ability or the inability to ensure machining accuracy and surface integrity is known as tool/grinding wheel failure. Industrial statistics have shown that tool failure is the primary factor causing machine tool failure and downtime, accounting for between one-fifth and one-third of the total downtime of NC machine tools. Personally, I believe that reducing accident rates is an important aspect of post sensor technology for precision machining, and we should be very clear about it, Machine tools may also cause equipment or personal safety accidents, or even major accidents during processing. Nowadays, high-end machine tools are equipped with tool detection sensors to effectively prevent the occurrence of such incidents. In fact, many customers often say that pretending to be a sensor also costs a lot of money. In fact, if you are smart and can calculate, the boss will definitely find that with this technology, it can greatly improve production efficiency, reduce waste, and reduce costs, especially with very high safety.
