The CNC Lathe Training Systems provide training in computer-aided design (CAD) and computer-aided manufacturing (CAM) using an industrial-grade microprocessor-driven CNC lathe. The systems allow students to practice computer numerical controlled (CNC) code programming and editing, learn to operate lathe components, controls, and tools, set a programmed reference zero, follow the steps necessary to turn a specified part, and apply the machine code language to current lathe technology.

The CNC lathe consists of a horizontal lathe constructed with a cast-iron bed, headstock, and tailstock. The lathe uses two ball screws, each driven by a stepper motor, to move the cross slide that carries the cutting tool along the Z axis (right and left) and X axis (in and out) with maximal positional accuracy. The speed of each stepper motor can be programmed separately for feed rates up to 762 mm/min (30 in/min). A 746 W (1.0 hp) motor rotates the spindle and three-jaw chuck, and thus the stock, at speeds programmable up to 3400 r/min. To facilitate maintenance, the Z-axis ball screw is protected by a dust cover.

The CNC lathe can machine pieces of soft materials such as plastic and wax, as well as harder materials such as aluminum, mild steel, and brass. Pieces can be turned into a variety of cylindrical bumps, grooves, and hollows. The CNC lathe is capable of threading using an optical-encoder feedback loop.

A computer is used to create NC part programs with G and M machine codes or their conversational code equivalents. The created programs are downloaded to the on-board microprocessor of the CNC lathe, which stores and executes them. Since the CNC lathe connects directly to the serial or Ethernet port of a computer, or directly to a network, no additional interface card is required. The computer is free to be used for any additional applications since it is not dedicated to the control of the lathe.
