I want to build a 4 axis cnc routerto do lateral movements with the spindle (as shown in the figures below, with the cutting toolout of the line of the axis of rotation ). Not yet have a 4 axis. If I insert geometries on g-code generatorssoftwares (Mastercam, Bobcad, etc) with holes like this in the figure below (to 4th axis), the tool need to side movements (like cutting cnc Video below). The G-code generatorsfor 4 axesalready consider the machine can move laterally or so I need to modify the machine? This type of movement is considered normal for a 4-axis machining or is it something special? Mach3can control it?




PLEASE, SEE THE VIDEO:

Sorry for the question. Generally I have seen with fourth axis cuts where the cutting toolonly moves upwards and axial direction (and not radial like the figure). Then I saw this video, where the cutting toolalso moves laterally.
