What is the orientation of NC machining?

XY positioning is easy. Just remove the vice and install it with a cutting fixture. Just use the arc to mill the workpiece, mainly on the Z axis. There's nothing I can do. 1 means to fill the difference between the highest points of each marked workpiece in the common coordinate system, which is troublesome for each workpiece. 2. Put the workpieces together in advance, which will be quick. You don't need to type a form for each work. If your machine tool is advanced and this product is relatively large, it is most convenient to equip it with an automatic edge finder (usually equipped with a high-speed machine), just like the three coordinates of the inspection room.
