(2) By changing the cutting parameters and tool geometry, the overlap coefficient can be reduced, such as turning the excircle with a right-angle offset tool.
③ Reduce cutting speed and increase feed, main deflection angle and rake angle;
(4) appropriately increasing the cutting speed; Improve the machinability of the processed material.
⑤ Increase cutting damping; Appropriately reduce the rake angle of the tool; Grinding the side damping edge; Appropriately increase the cross edge of the drill bit; Properly make the tool tip higher than (the outer circle of the car) and lower than (the inner hole) the center line of the workpiece to obtain a smaller working clearance angle. In order to reduce the high frequency vibration of the tool, it is suggested to increase the rake angle and rake angle of the tool.
⑥ Adjust cutting speed to avoid critical cutting speed. When cutting, turning the end face or using wide-edged tools, forming tools and thread tools, the cutting speed should be less than the critical cutting speed. When turning the end face of annular workpiece vertically, the cutting speed is greater than the critical cutting speed.
⑦ Improving the rigidity of the process system can improve the vibration resistance. When installing the turning tool, it is not advisable to extend too long, and the boring tool should be as short and thick as possible; Try to shorten the extension length of tailstock sleeve; When machining the slender shaft, the vibration can be eliminated by using the center frame or tool rest, or using the slender shaft turning tool with large main deflection angle.
⑧ As far as possible, do not use the cutting speed which is easy to produce chip accumulation tumor.
Pet-name ruby adopt appropriate cutting parameters. The method of reducing the cutting width and increasing the cutting thickness can be adopted.
