A 17-inch bright TFT LCD screen. Frequency spindle uses a Panasonic inverter. AC servo system uses the Sanyo AC servo drives, PMAC card chose PMAC2A-PC104, mechanical parts using a ball screw drive, servo motor AC servo unit and formed a close-loop speed control system. Installed in the working platform grating ruler moving away from direct measurement of the mechanical parts, and other components to form a closed loop position control system; through the installation of the AC servo motor shaft to serve as an incremental encoder position sensor for the indirect measurement of the mechanical parts mobile distance with other components to form a position of semi-closed loop control system. IV.PMAC MOTION CONTROL CARD PMACs full name is the Programmable Multi-Axis Controller. It is Deltu Tau Data System Inc. produced a series of broad support for a large number of programmable multi-axis motion control card. PMAC as a high-performance servo motion controller, digital signal processor (DSP), and a flexible high-level language to control up to eight axes at the same time exercise. PMAC to an unprecedented multi-axis controller provides cost-effective, using Motorolas DSP56 series digital chip as the CPU, to handle all eight axes calculations. Stored in its internal procedures in making a separate operation, the implementation of sports programs, PLC program, to servo loop update. Enabling real-time multi-tasking, which makes it a task switch in processing time and greatly reduces the host and programmer of the burden of the whole control system can improve the speed and control accuracy. The numerical control system selection model is PMAC2A-PC/104, it is standard 40MHZ DSP master clock, optional 60/80MHZ, PC104 bus and stored with flashmemory campaign procedures, etc.; standard 4-channel PWM digital output, variable for the pulse + dir digital signal or the DAC 10V analog output with a resolution of 12 bits; standard RS232 serial port, optional USB or Ethernet communication; each axis is equipped with dedicated LIMIT (limit), HOME (back to zero) , FAULT (servo alarm), USER (user-defined) and AENA (servo enable) input and output signals. V. CNC ENGRAVING AND MILLING MACHINE MAN-MACHINE INTERFACE DESIGNThe numerical control system software using VB and the Delta Tau provided pmac.dll dynamic link library preparation. Through the Delta Tau PComm32PRO communication driver is a Windows 98/ME/2000 and XP environment, the establishment of PMAC application development tool, you can set up and use more than 400 performance function. This program is designed to be powerful, fast, and portable use function 8. PComm32PRO the PMAC can be common in all devices and communications. PComm32 contains a total of more than 250 small functions. The numerical control system software to achieve the following functional modules: 1). Mechanical parameter setting module. Mechanical parameters typically include pulse-equivalent, the pivot point moving speed, the pros and cons of various axle limits to software such as stroke. Request this software system provides a dialog to the user modify the mechanical parameter values, when the host and PMAC to establish communications, these mechanical parameters can be automatically assigned to the corresponding PMAC variable, set the controller so as to achieve the purpose of the system constant value. Shown in Figure3 below: Fig. 3 Machine parameter setting module PMAC values obtained are generally pulse volume, by calculating the amount of displacement roller screw and encoder speed and PMAC in the internal settings to turn it into mm, mm / s units. (As a motor as an example) Location coordinates to obtain a machine tool motor program: PmacGetResponseA (DeviceNumber, response, 255, # 1 p) Pulse is converted to equivalent amount of displacement process: Format (Val (response) / 1638.4, #.#) 2).

Fig. 5 motor jog Module 5). Motor back to the zero module. The module can be achieved automatically return to the work of the origin of X-axis, Y-axis automatically return to the work of the origin, Z-axis automatic return to the work of the origin of. PMAC cards have a set of hardware to capture the origin of the internal switch mechanism that can automatically return to the origin of all axes motors automatically. When the PMAC motion control card built-in hardware capture mechanism was found when the action switches back to the origin, it will capture the origin and precise location, and in accordance with a certain trajectory back to that location. The system adopts the PLC controls back to zero, so that control the direction of a positive return to zero. 6). Tool library information. The module can input and display tool compensation information. Cutter Compensation can be used to enter information into the tool library, to facilitate adjustment to compensate for Automatic Tool Changer. 7). Monitoring module. The module is able to complete the following two functions: First, update the interface information, including X, Y, Z axis program coordinate, X, Y, Z coordinates mechanical, X, Y, Z axis speed; 2 is to monitor the safety of all I go information, including machine status, alarm system, restrictions. When a security failure, the module can be automatically recorded in the following types of security failure, time and other information, and will be credited to the kinds of text documents available to the manipulator, shown in Figure 6. Fig. 6 Monitoring Module 8). Download the implementation of sports program modules. The module can be the standard G-code files into a blank card can be identified PMAC axis motion program or PLC programs to read and can be downloaded to PMAC axis blank card.Download PmacDownloadA (DeviceNumber 0,0,0, CommonDialog1.FileName, True, True, 1, True) 9).
