Example Embodiment
[0058] The present invention will be further described in detail with reference to the accompanying drawings and embodiments. The following embodiments are for explaining the present invention and the present invention is not limited to the following embodiments.
[0059] Such as Figure 1~3 As shown, a right-angle cutting chatter analytical modeling method includes the following steps:
[0060] Step 1. Establish a dynamic model of right-angle cutting chatter
[0061] Determine the geometric parameters of the tool, the rake angle α, the unit is deg, the relief angle γ, the unit is deg; the selected cutting parameter, the cutting speed V, the unit is m / min, the feed amount f t , The unit is mm / r, the cutting width b, the unit is mm; in the metal cutting process, the change of the cutting thickness will cause the fluctuation of the cutting force, the cutting force and the cutting thickness change according to a specific cycle, and form a closed loop The feedback system calculates the ...
