Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with embodiment.
[0032] The present invention is based on the cutting force coefficient identification method of CNC machine tool spindle and servo shaft power, comprising the following steps:
[0033] Step 1: Arrange test sensors on the CNC machine tool. The test sensors are current sensors and voltage sensors. Specifically, the current sensors are respectively connected to the three-phase input terminals of the motor under test, and the cables are passed through the middle through hole of the current sensor. Pass through, connect the voltage sensor to the input terminal of the motor through wires and terminals, and connect the output signal line, connect the output terminals of the current sensor and voltage sensor to the data acquisition card or transfer through the terminal, and then control the current and voltage signals are collected. In the present embodiment, the CNC lathe used mai...
