VF series mills are a range of 3-axis vertical machining centers, which can be outfitted with 4th and 5th axis drives if so configured. These mills are available in different sizes, ranging from VF-1 to VF-14. The VF in the name stands for "Very First" as the first machine Haas produced was the VF-1 ("Very First One").
CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
Motion is controlling multiple axes, normally at least two (X and Y), [4] and a tool spindle that moves in the Z (depth). The position of the tool is driven by direct-drive stepper motors or servo motors to provide highly accurate movements, or in older designs, motors through a series of step-down gears.
Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine.An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis.
Numerous; mainly Siemens Sinumerik, FANUC, Haas, Heidenhain, Mazak, Okuma G-code (abbreviation for geometric code ; also called RS-274 [ citation needed ] ) is the most widely used computer numerical control (CNC) and 3D printing programming language .
The work spindle is referred to as the C axis and, if a rotary table is incorporated, its centre line is the B axis. Horizontal boring machines are often heavy-duty industrial machines used for roughing out large components, but there are high-precision models too.
The second cylinder rotates with the first. The axes of the two cylinders are always parallel, but the mating faces are able to slide against each other. Thus the second cylinder can rotate about a different, but always parallel axis to the first. As the second cylinder approaches the edge to be located, it is pushed into alignment with the first.
For positive y- and z-axis, we have to face two different conventions: In case of land vehicles like cars, tanks etc., which use the ENU-system (East-North-Up) as external reference (World frame), the vehicle's (body's) positive y- or pitch axis always points to its left, and the positive z- or yaw axis always points up. World frame's origin is ...
