A single-point tool has only one cutting edge, while a multiple-point tool has two or more cutting edges . 单刃刀具只有一个切削刃,而多刃刀具有两个或两个以上的切削刃。
Dynamics of discrete system with friction and multiple - point impact 受到多点打击的非理想离散系统冲击动力学
Friction ; multiple - point impact ; discrete system ; piece - wise ; impact dynamics 摩擦多点打击离散系统分段冲击动力学
The purpose is to study the solution of impulsive dynamics of planar discrete system with friction and multiple - point impact 研究受到多个打击的离散系统考虑库仑摩擦时动力学的求解方法。
Aiming at the shortcomings of the routine inverse analysis methods which only utilize the data of single - survey - point and single - direction , a new method is brought forward in which the deformation observation data of multiple - point and multiple - direction are made use of the inverse analysis 针对利用单测点单方向位移资料进行反演的不足,提出用多测点多方向位移资料进行反演的方法。
