The system allows students to practice computer numerical controlled (CNC) code programming and editing, learn to operate mill components, controls, and tools, set a programmed reference zero, follow the steps necessary to machine a part to programmed specifications, and apply the machine code language to current mill technology. The CNC Mill can machine pieces of soft materials such as plastic and wax, as well as harder materials such as aluminum, mild steel, and brass. It consists of a milling table, a headstock carrying the spindle motor, and a cast-iron vertical column with dovetail slide. The CNC mill is mounted on a solid steel chassis and is equipped with R8 tooling. The stock to be milled is secured in a vise that holds it to the milling table. Two ball screws, each driven by a stepper motor, are used to move the table along the X axis (left and right) and Y axis (backward and forward) to feed the stock through the periphery of the end mill. A third ball screw, also driven by a stepper motor, is used to move the headstock along the Z axis (up and down) for positioning the end mill. The speed of each stepper motor can be programmed separately for feed rates up to 508 mm/min (20 in/min). A 746 W (1.0 hp) dc motor rotates the spindle at speeds programmable up to 3400 rpm. The end mill can be changed to accommodate different stock materials and milling designs. 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 mill, which stores and executes them. Since the CNC mill 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 mill. The CNC mill is designed for use with the included CNC Mill Software, Model This Windows - based software allows the creation of G and M code part programs for download to the CNC mill. It features tool path emulation, which allows students to set up the tool paths and cut steps, and create a part program to simulate tool motion on a monitor in order to verify NC codes and the finished part prior to the actual cutting. Canned cycles can be programmed. The software can import NC part programs created with other CAM programs that support G and M codes. The CNC mill features a control panel that allows manual operation. This panel includes a multiple-line LCD display, an easy-to-use membrane keypad, an error indicator/pause button, and a key-released emergency stop push button. The mill parameters, including the spindle speed, the feed rate, the reference point, and the X, Y, and Z axes coordinates can be set by accessing different menus. During the machining, the control panel displays the X, Y, and Z axes coordinates, as well as the current feed and spindle speed. 2 Festo Didactic

3 The CNC mill is designed for maximum safety. Safety doors provide protection during machining. Magnetic interlocks located on the doors stop the spindle and the axes if a door is opened during machining. Limit switches prevent over-travel of the mill's spindle and table. Pressing the emergency stop push button on the control panel cuts off the power to the spindle motor and stops the axes. The CNC mill supports low-voltage communications with robotic units to permit students to create automated work cells, ideal for implementing computer-integrated manufacturing (CIM). For this purpose, the CNC mill features a 15-pin TTL/IO port providing four 5 V digital inputs and four 5 V digital outputs for TTL communication to an automation work cell. This port can be connected to the Servo-Robot, Model 5250, offered as an option to achieve automatic loading and unloading of the stock with a robot arm. The CNC mill also features a 5-pin solenoid driver port providing connections for up to four auxiliary devices. This port can be connected, for example, to the pneumatic control box of the optional Pneumatic Vise, Model 5616, to achieve automatic clamping and unclamping of the stock loaded in the CNC mill. The TTL/IO and solenoid driver ports of the CNC mill are M-code supported through the CNC Mill Software, Model The CNC Mill Training System comprises the accessories, software, and cables required for system operation. These include a vise, a basic milling set, 100 blocks of industrial machinable wax, a serial cable, a cross-over Ethernet cable, and a copy of the CNC Mill Software, Model The system also includes two user guides. The first user guide allows students to acquire experience with the equipment commonly found in automated manufacturing environments. The second user guide covers the operation of the CNC Mill Software. Various assortments of milling tools and stock materials of different sizes are offered as options to enhance and expand system capabilities.
