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.
In its early days, Mastercam combined ease of use with powerful programming capabilities, allowing users to design parts and control CNC machines to manufacture parts precisely. The first version of Mastercam was released in 1983 [ 5 ] and was one of the first to introduce CAD/CAM software designed for both machinists and engineers, enabling ...
Today's CAM systems support the full range of machine tools including: turning, 5 axis machining, waterjet, laser / plasma cutting, and wire EDM. Today’s CAM user can easily generate streamlined tool paths, optimized tool axis tilt for higher feed rates, better tool life and surface finish, and ideal cutting depth.
Drilling and tapping operations are also possible on a 2.5-axis mill. 2.5D objects can be machined on a 3-axis milling machine, and do not require any of the features of a higher-axis machine to produce. CNC machines use G-code and M-code in order to control the machine and the positioning of the spindle.
All CNC machine tools are automatic, but the usage in the machining industries does not routinely call them by that term. The term "automatic", when it is used at all, still often refers implicitly to cam-operated machines. Thus a 2-axis CNC lathe is not referred to as an "automatic lathe" even if fully automated.
Haas Automation, Inc is an American machine tool builder headquartered in Oxnard, California.The company designs and manufactures lower cost machine tools and specialized accessory tooling, mostly computer numerically controlled (CNC) equipment, such as vertical machining centers and horizontal machining centers, lathes/turning centers, and rotary tables and indexers.
Three-axis systems including the X, Y, Z axes are common on milling machines; those plus U and W are used on highly sophisticated 5-axis vertical machining centers. Lathes or cylindrical grinders typically use just X and Z axes, while a surface grinder may use only a Z axis.
A CNC dividing head may be used in this manner on either manual or CNC machinery. Most CNC dividing heads are also able to function as a full CNC axis and may be wired into the control of a CNC machine. This enables the machine's main CNC controller to control the indexing head just like it would control the other axes of the machine.
