Engraving Control System
Googol's inverted pendulum system is a nonlinear unstable system, an ideal experiment platform for teaching control theories and conducting various control experiments. Many abstract control concepts, such as the stability and the controllability of a control system, can all be shown visually through the inverted pendulum system. In addition to educational purposes, an inverted pendulum is also an excellent tool for researchers of modern control theories. Through continuous research,  new control methods haven been developed and then applied to high-tech industries such as aeronautical engineering and robotics.
The engraving control system is developed based on Googol's GE-300-SV/SG series PC-based open-architectural motion controllers, especially for 3-axis engraving (engraving and milling) machine control. The high responding and processing speed of the system enables the system to control motor accurately and realize 3D linear and circular interpolation. The system fulfills the fine engraving of complicated graphics by simple operations.

Technical Features:

  • In a high-speed DSP core as a control for all-digital servo control, achieving linear, precise circular interpolation
  • Analogue of a servo control, processing of high surface finish, smooth operation
  • Provide a strong G, M instruction compiler system can support MasterCam, Cimatron, UG, PowerMILL such as a common CAD / CAM software, interface flexibility
  • Practical Windows user interface simple, complex graphics precision carving
  • High-speed 2D and 3D preview
  • Display the machining track in real time.
  • Provide G code editor. Input or modify a machining file manually.
  • Provide coordinate processing such as the rotation and mirror of coordinate.
  • Shortcuts wealth of features that make operation a success
  • 500 Prospect of pretreatment (Look ahead), the processing speed of 50 percent, corner smoothing machine small impact
  • Embedded processing a variety of strategies so that the users can be processed at the different processing technology for flexible options to improve processing
  • Processing speed and efficiency
  • Processing time can be adjusted manually and automatically processing rate
  • Rich alarm function, fully embody the human system design
  • Arbitrary start of the function, reduce duplication of large processing time and improve processing efficiency
  • Arbitrary location of the suspension, arbitrary position to continue to facilitate the operation of the user, reducing the possibility of non-operation
  • Provide grammar self-check, error prompt, pause and soft limit and hardware limit functions.
