科技界对大自然和生产工程中出现的某些振动现象感到忧虑并设法来控制和消除之。但是对这一物理现象应该给予全面的评价,把振动作为有利的因素来改善传统的现状是一种新的学术思想。 机械加工中出现的毛刺虽小,危害极大,它的存在严重地影响产品的装配精度和使用性能,即使是自动化生产十分发达的国家,有时也不得不用手工去除毛刺以保证产品质量,因此, The tech community is concerned about some of the vibrations that occur in nature and production engineering and is trying to control and eliminate it. However, it is a new academic thought to give a comprehensive evaluation of this physical phenomenon and to improve the traditional status quo by using vibration as a favorable factor. Machining burr appears small, extremely harmful, its presence seriously affect the assembly accuracy and performance of the product, even if the automated production is very developed countries, sometimes have to manually remove the burr to ensure product quality, therefore,
