The control of layer thickness by changing energy input. When the powder feed conditions were constant, the layer thickness was increasing with the increase oftemperature of melt pool.
改变能量输入的层厚控制：送粉条件不变时，熔覆层厚度随熔池温度的增加而增加，通过控制激光功率或扫描速度可以实现熔覆层厚度的反馈控制。
Experimental results show that higher efficiency can be accomplished and bigger layer thickness and bigger servo feed rate can be chosen in UED-Milling in gas with the aid of ultrasonic vibration.
实验表明，施加超声振动不仅可以提高铣削加工的材料去除率，还可以较大的分层厚度和伺服进给速度进行加工。
