Example Embodiment
[0032] Example 1:
[0033] This embodiment discloses a method for online monitoring of milling tool defects, see figure 1 , Including the following steps:
[0034] 1) See figure 2 , Establish a three-dimensional space coordinate system oxyz with the machine tool spindle as the center. Among them, the z axis is located on the axis of the machine tool spindle, and the x and y axes are respectively perpendicular to the z axis. Install the vibration sensor module on the machine tool spindle, start the machine tool spindle, and debug the vibration sensor module to ensure that the signals in the x, y, and z directions meet the requirements.
[0035] 2) See image 3 , The initial sample data collection. specifically,
[0036] 2.1) Take one revolution of the spindle as a cycle T 0 .
[0037] 2.2) In this embodiment, the number of blades on the cutter head is 4, and the blade numbers are 1, 2, 3, and 4 respectively. When the 4 blades on the cutter head enter normal milling, the vibration sen...
Example Embodiment
[0051] Example 2:
[0052] This embodiment discloses a relatively basic implementation, a method for online monitoring of milling tool defects, see figure 1 , Including the following steps:
[0053] 1) See figure 2 , Establish a three-dimensional space coordinate system oxyz with the machine tool spindle as the center. Among them, the z axis is located on the axis of the machine tool spindle, and the x and y axes are respectively perpendicular to the z axis. Install the vibration sensor module on the machine tool spindle, start the machine tool spindle, and debug the vibration sensor module to ensure that the signals in the x, y, and z directions meet the requirements.
[0054] 2) See image 3 , The initial sample data collection. specifically,
[0055] 2.1) Take one revolution of the spindle as a cycle T 0 .
[0056] 2.2) In this embodiment, the number of blades on the cutter head is 4, and the blade numbers are 1, 2, 3, and 4 respectively. When the 4 blades on the cutter head ente...
Example Embodiment
[0068] Example 3:
[0069] The main steps of this embodiment are the same as those of embodiment 2. Further, in step 7), if the subsequent two consecutive sets of data do not satisfy It can be ruled out that the phenomenon of increased local vibration due to casting or forging defects during tool cutting, rather than increased vibration caused by tool defects, goes to step 8).
[0070] Example 3:
[0071] The main steps of this embodiment are the same as those in embodiment 2, and further include step 9). If the alarm module does not issue an alarm during the whole machining process, the data comparison and analysis module records the machining parameters of the whole process, and the collected strong vibration cutting After the wave data analysis process obtains the cutting wave area, save it and save it as the signal comparison sample material for the later processing of the same kind of workpiece.
