The use of embedded computer (EIP) technology, CNC machine tools have a wide range of adaptability, only need to change the input program instructions when the processing object changes; processing performance is higher than the general automatic machine tools, can accurately process complex profiles, and thus suitable for processing Lots of small and medium-sized batches, frequent modifications, high precision requirements, and complicated shapes, and good economic results With the development of numerical control technology, the number of machine tools using numerical control systems is increasing, including lathes, milling machines, boring machines, and drilling machines. Grinding machines, gear processing machines and EDM machines.
[System Principle] CNC machine tools mainly consist of numerical control device, servo mechanism and machine tool body. The program instructions input into the numerical control device are recorded on the information carrier, and are read by the program into the device, or manually input by the keyboard of the numerical control device. The numerical control device includes a program read-in device and an input portion, an arithmetic portion, a control portion, and an output portion composed of electronic circuits. The numerical control device is divided into three types according to the control functions that can be achieved: point control, linear control and continuous trajectory control. [System Configuration]
This article takes a high-performance numerical control system of CNC company as an example to introduce the application of EVOC series embedded computer (EIP) in CNC system. I. Numerical control unit: 1. Embedded computer: l 19' rack-mount standard structure, NEMA 4/12 aluminum waterproof, dust-proof front panel; l 10.4'TFT color LCD display; l configuration EVOC 586 embedded computer Motherboard; l EVOC 8-slot industrial control chassis (including switching power supply); l Two sets of membrane keyboards, with grounded metal mesh; 2. Servo control serial communication card, six-axis position loop control card, four-axis digital servo control card ( Optional); 3. Built-in PLC input card (48 channels/card), built-in PLC output card (48 channels/card). Note: The technical parameters of the EVOC 586 embedded computer motherboard (HSC-1511CLDNA) are as follows: A. Structure: ISA bus Half-embedded motherboard B, CPU: On-board INTEL PENTIUM MMX 266 Low-power CPUC, Memory: On Board with a 144-pin DIMM slot, maximum support 256M memory D, Display: SM712 graphics chip + 2M independent memory, support for CRT, 24-bit LCD display E, Interface: 2 IDE, 1 FDD, 1 and 2 strings, 1 KB/MOUSE interface, 2 USB. F, SSD: Support DOC electronic disk G, PC-104 interface: There are II, spindle system: spindle drive unit + spindle motor, inverter + spindle motor, inverter + asynchronous motor. IIIã€Feeding system: HSV-11D AC permanent magnet synchronous servo drive and servo motor, various analog and digital servo systems at home and abroad, HC5801/5802 series stepping motor drive unit and motor, HG.BQ3-5B three-phase Sine wave hybrid driver and stepper motor. [Systematic evaluation] The system adopts EVOC series embedded computer (EIP) and TFT true color liquid crystal display. It has multi-axis multi-channel control capability and built-in PLC, which can be used with a variety of servo drive units. With the advantages of good openness, compact structure, high integration, good reliability, high performance-to-price ratio, and convenient operation and maintenance, it is a new generation of high-performance, high-end CNC system suitable for China's national conditions.
