Technical relationship between tensile testing machine and sensor

Source: Tensile testing machine Key words: January 11, 2019 Tensile testing machine sensor technology    

As for the operation of the tool, the secondary sensor detection indicators include drive system, bearing and rotation system, measurement monitoring and control and safety, etc., and the sensor parameters include the fault shutdown time of the inorganic bed, the nominal roughness and machining precision of the added parts, work rate, tool shape and the flow rate of frozen smooth liquid. Many sensors, such as TV or CCD based tool hearing sensors and laser nominal roughness sensors, will be adopted or developed to realize the identification and supervision of the agency. The indicators of cutting process sensor detection include cutting force and its change, cutting process tremor, contact between machine tool and workpiece, chip shape and cutting process identification, etc. the most important sensing parameters include cutting force, cutting process vibration, cutting process acoustic emission, cutting process generator power, etc.
Sensor skills in the process of making parts
The methods of cutting process sensing detection are to optimize the consumption rate of cutting process, create profit or (nonmetal) data removal rate, etc. The statistics of light industry confirm that the machine tool is the primary factor that causes tool failure and the downtime caused by it accounts for 1 / 5-1 / 3 of the total downtime of NC tools,
It can also cause facilities or life insurance incidents, even serious incidents. Machine tool detection sensor can effectively prevent the occurrence of such things. Since the 80's of the 20th century, the request for work piece identification and supervision of the position and posture of the work device has also been on the agenda.
Thus, the workpiece identification and workpiece device can also be used to monitor and sense the machining allowance and nominal defect of the blank to be processed or the workpiece.
Electronic tensile testing machine Compared with the process supervision skills of machine tools and tools, the process supervision of workpiece is the earliest and most used. When the machine tool and the mound are worn to a certain limit (determined according to the grinding blunt specification) or appear to be broken (rotten, chipped edge, scald, plastic deformation or coiling tool), so that they can be cut (grinding power or unable to guarantee the processing precision and nominal integrity, the machine tool / mound is called effective).
To be precise, chronological identification is to identify whether the processing chronology implemented is the chronological sequence of the work (part) processing request; the work piece identification is to identify whether the workpiece or the blank that is sent to the tool to be processed can be the workpiece or blank requested to be processed, and whether the position and posture of the workpiece device is the position required by the process specification.
