The invention provides a device for testing and monitoring vibration of a rack, vibration and deformation of a saw web cutting edge, machining noise, saw shearing force and torque of the machining process of an inside diameter slicer. The device is mainly composed of a motor speed controller, various sensors and a connection component. The motor speed controller controls the cutting speed of the inner diameter slicer; an acceleration sensor is used for measuring the vibration of the rack of the inside diameter slicer; a displacement sensor is used for measuring the vibration and deformation ofthe saw web cutting edge of the inside diameter slicer; a sound sensor is used for measuring the machining noise; and a six-axis force sensor is used for measuring the saw shearing force and the torque. During a machining process, the rotation speed of the principle shaft is continuously changed, and the encoder is used for measuring the rotation speed of the whole course of the machining processin real time. The test device is simple in structure, convenient to assemble and low in cost, can measure and monitor the multiple physical quantities in real time during the machining process of theinside diameter slicer, and provides a new method for monitoring the machining process of the inside diameter slicer; the measured data can provide reference for improving the saw machining accuracyof the inner circle.
