Description

Device is tailor to dysmorphism flexible material based on suspension vibrations are restrained Technical Field The invention relates to a special-shaped flexible material cutting device based on suspension vibration suppression. Background The special-shaped flexible material is a flexible material with uneven thickness, toughness, hardness and the like at all parts of the material, and when the efficient cutting operation is carried out, the existing cutting mode is heavier due to a transmission mechanism, so that the cutter generates larger movement acceleration in each acceleration and deceleration process, and the weak vibration of the cutter is reflected in the cutting effect. Even with more rigid devices, the relatively high inertia of the drive train can lead to slight chatter at the tool end, which is to be avoided to the greatest extent for fine cutting as well as for efficient cutting. On the other hand, the materials with different toughness and hardness have different acting force forms on the cutter in cutting operation, and particularly when the cutter cuts uneven materials, the cutter can be subjected to aperiodic random impact, so that the cutting quality can be greatly influenced for efficient cutting operation.
