Meanwhile, in the production process, the machining center equipment needs to replace a new cutter and an old cutter according to the service life of the cutter, an operator manually detaches the old cutter and fills in information cards such as the service life of the cutter when the cutter is off the machine; meanwhile, an operator carries out new cutter mounting and inputs the service life, the cutter length, the cutter repair and the like of the cutter into the machine tool.
Two modes of two-dimensional codes and RFID are generally adopted for reading the cutter information at present. The two-dimensional code reading defect is that machining equipment mainly depends on clamp positioning and processing contents such as drilling and milling of various special cutters matched with emulsion, the emulsion is occupied on the surface of a workpiece, reading of the two-dimensional code can be affected at the moment, reading failure is caused, and the success rate of reading of the two-dimensional code is reduced due to the influence of light inside a machine tool. The RFID reading method has the defects that the heavy engine workpiece is large in size, the length exceeds 1 meter, the height and the width are all more than 50 centimeters, the postures of all stations are different, the installation position of the code carrying block is fixed, the process installation empty position is even retracted inside in order to prevent the machining interference of a cutter, and long-distance reading and writing are needed at the moment. And the cutter size is small, the arrangement of cutters in a cutter base in the machine tool is compact, and if long-distance reading and writing are carried out, other cutters can be wrongly read and written, so that the RFID of the cutters needs short-distance reading and writing.
Therefore, the traditional RFID wireless transmission method for single-frequency reading and writing cannot simultaneously ensure effective data reading and writing transmission of workpieces and tools, and the current common method is to adopt 2 sets of processors with different frequencies for reading and writing, and the method has high cost, and simultaneously has poor expandability due to single frequency.
