Using the system to draw piping figure, can enhance far and away drawingvelocity .
使用本系统绘制配管图，可以极大地提高绘图速度。
2
Data of drawingvelocity that is automatically measured by precise extrusion were analyzed.
对精密挤出控制系统自动测量的牵引速度数据进行了分析。
3
The results show that the maximum temperature of the die has a nearly linear increase with the increase of drawingvelocity or the increase of friction coefficient.
