The Woodpecker® CNC engraving machine Sai-O 2 control systems is based on the Microsoft Windows 98® or Windows 2000® operating systems. The multi functions are simple to learn and operate. Compared with the traditional CNC systems, the Sai-O 2 is a more open, multi-tasking system and can be easily set up in a network environment.

This system retains all the functions of traditional CNC systems, plus the additional features of 3D tracking, automatic detection of the cutting tools, break point memory, rotating axis, procedure jumps and other high level functions. The system is compatible with multiple types of input devices and data feeds including standard G code and HPGL. It can interface directly with CASMATE®, MASTERCAM®, UG® and other commonly used CAD/CAM software. It can also interface with two dimensional design software applications such as AutoCAD® and CorelDraw®. Sai-O 2 works on two or three axis and may expand to multiple axes to satisfy the user requirements.

Advanced Interface

The system is controlled via a standard keyboard and mouse. Processing of the work can be tracked on the monitor in a three dimensional view. Ease of operation, direct viewing of the work in process and simple search commands for the processing files makes these a very user friendly system.

Complete G and PLT instruction support

To fully support the G instruction set, it has the complete G and M instruction collection. PLT format is also supported. The user may directly output PLT format from programs such as AutoCAD® software for use in the system. Compilation of the G and M instructions is extremely fast and precise.

The auto adapt speed algorithm

In traditional CNC system, between two G instructions, link up speed usually is a fixed value. In this system, an advanced processing speed adaptive prediction algorithm is used. This algorithm uses the speed, the size, the direction, the maximum accelerating speed, as well as a forecast function. The auto adapt speed algorithm links the speed to the next instruction. This increases the processing efficiency (approximately from 30% to 300%), moreover it improves the workability and helps decrease surface grain imperfections.

Three dimensional simulation display function

The three-dimensional simulation function, displays in real time, the tool path and can be revolved in three-dimensional space with an enlargement and reduction feature. The user can from any angle observe the three-dimensional processing results, which provides a more accurate view of the results.

High speed simulation function

Can perform a fast simulation of the processing procedure. The processing path can also be simulated in an extremely short period of time and the results can be viewed from a three-dimensional angle. Simultaneously, the user may also analyze the processing data for accuracy and determine the actual processing time needed, processing scope, cutting tool service conditions and so on.

Automatic function

Manual Data Input (MDI) function, break point memory, step-by-step function, ability to jump to other operations. These functions help the user fix any potential errors and obstacle. The controller also has a function to recall the original starting point while working at each axis.

Convenient, complete manual function

Also supports input devices, like a joystick and the electronic hand wheel, which along with a keyboard and mouse allow complete operation of the system.

The Woodpecker® CNC engraving machine Sai-O 2 control system increases the functionality of the original system. Enhancements include original starting point memory, large G command file, system diagnosis, operation diary, immediate processing document management, speed regulation, main spindle speed control, high-level MDI and so on. All these functions allow for simple and complete control of the CNC engraving machine.
