![]() 5th axes are used for more intricate parts where undercuts are prevalent. ![]() True 3D carving generally requires a 5 axis machine with sufficient articulation to reach a bit in from any angle. It is typically a rotary table on top of the 4th axis rotary table, otherwise known as a trunnion. Top-down milling is referred to as 2.5D milling because it is more than 2D but cant produce a complete 3D image like say, a horse figurine because it cant reach under the belly. 5th axis adds one more dimension than the 4th axis. You will most often need a CAM program equipped with 4th axis capabilities to create a tool path for any part you plan on cutting using a rotary table. The 4th axis can be used for full contouring with other axes, indexing, or flipping a part over. 4th Axis milling usually describes situations where a rotary table is involved in the cutting process in addition to the X, Y and Z axes. You will most often need a full CAM program to create g-code files capable of performing 3D contouring.Ĭustomers also have the option of using more than three axes in 3D part creation. 3D contouring can then be accomplished by creating curves that use all three axes at once, like in a helical cut. At the heart of the Bantam Tools Desktop PCB Milling Machine is the TinyG motion controller. Working in three dimensions (3D) means that you have the ability to control at least three axes simultaneously. VCarve is a powerful software program for 2.5D milling. Most simple CAM programs deal with 2.5D parts. ![]() The Z axis then retracts so the X and Y axes can move to the start point of the next feature, which may be cut at a different Z depth than the last feature. During a 2 ½ D cutting process, the Z axis positions itself to a depth where the X and Y axes interpolate to cut a feature. CAD-CAM Hypermill & Mastercam We have two powerful, comprehensive CAM solutions for precise and accurate programming of various 2.5D, 3D and 5-axis milling. Working in two and a half dimensions (2.5D) means you are cutting a part that has multiple flat features at varying depths. The FlashCut CNC software’s DXF Import feature automates the creation of a tool path from a 2D DXF file. This is common for laser, hot-wire, water jet, and plasma cutting, along with engraving. ![]() complete with all the extra stock that’s. The software will store a digital model of the part during each step of machining roughing, cutting, finishing, etc. Working in two dimensions (2D) means that you are cutting out a part with features that are all at the same depth. Stock Model gives users the ability to keep track of stock with an in-process model of the part that Mastercam stores and uses for different stages of machining. ![]()
