介绍了一种新的粗加工方法，即从工件上去除块状材料，以提高模具加工效率。该加工方法采用多轴数控机床和高性能钻头。使用多轴控制功能设置工件的第一个垂直于Z轴的表面后，进行钻孔，对其他表面重复此过程。

A new rough cutting method is described in which a lump of material like a block is removed from the workpiece to improve the efficiency of die and mold machining. A multi-axis CNC machine tool and high-performance drill are used in the machining method. After setting the first surface of the workpiece perpendicular to the Z-axis by using the multi-axis control function, drilling is carried out, this process is repeated for the other surfaces.
