The selection of distance between tool feeds has a great influence on machined surface roughness either in3-coordinates or2-coordinates linked millings. 无论是三坐标还是两坐标联动铣削,走刀行距的选择对加工表面粗糙度都有很大影响。
The shapes of the stone tools gradually increased, such as stone hoes, millings, hammers, knives, axes, gravers and stone containers etc, and the shapes of stoneware grew steady. 石器的形状从旧石器时代的少数几种发展为石锄、石磨、石锤、石刀、石斧、雕刻器,以及石制容器等等,并且石器的形状也逐渐趋于定型。
The optimized weight proportion of conductive particles and carbon in the is 6:4. The introduction of proper dispersive may decrease the paste resistance to 1/ 2. It is preferable to have the carbon paste passed four millings. 导电载体应使用质量比为6:4的石墨和炭黑的混合体,适当的分散剂可使电阻率降低1/2,碳浆研磨次数为4次;
