为改进对刀精度及速度，设计了标准试棒碰刀对刀的方法。

It has improved the accuracy and the speed of tool setting. At the same time, a tool setting approach with standard test bar touching cutter was introduced.

在表面粗糙度的影响因素和影响规律方面：主要研究了残留面积高度、走刀行距、每齿进给率和最优化走刀路径对零件加工表面粗糙度的影响。

For influence factors and rules of machined surface roughness, we studied on the influence factors of machined surface roughness such as scallop-height, path interval, feed rate and optimum tool path.

试验结果表明，甩刀末端线速度、甩刀工作密度、甩刀重复度及其交互作用对切碎机工作质量影响显著。

The experiment results show that the influence of tip linear velocity, working density, repeated level and their reciprocities on the cutter's working quality is remarkable.

Appropriately enough, he was stabbed to death in a traffic jam in Paris when his carriage gets blocked in the center of Paris, and this mad monk sticks a big knife into him.

他是在巴黎拥挤的街道上被刀捅死的,这对他的一生真是绝妙的讽刺,当时他的马车被堵在巴黎市中心,有个疯狂的修士用一把大匕首捅死了他
