With the continuous development of science and technology and manufacturing technology progress, digital control of engraving machine becoming a special tool of engraving industry.
Tell from the processing principle of CNC engraving machine is a combination of drilling and milling processing, is a typical electromechanical integration products, in the mold sculpture, advertising, decoration and other industries have extensive market applications.
Currently on the market of CNC engraving machine controller hardware platform of microprocessor mainly includes: an 8-bit single chip microcomputer as the kernel, price is low, this type of product design is simpler, but has a single function, poor performance, low efficiency, small storage capacity, independent working ability is weak, the practical performance is not strong, positioning accuracy is not high, the human-computer interaction complex, the convenient operation and no defect;
With DSP as kernel, this kind of carving machine has strong performance and efficiency, strong real-time performance, moderate cost, but the function is less, the same lack of ability to work independently, can't satisfy the human-computer interaction interface, peripheral interface circuit, network, etc.
Net operating system as a platform, completed by ARM speed control, the FPGA complete path control.
In trajectory control is a combination of the stepper motor torque -
Frequency characteristics, the motor is accurate and stable.
The whole control system integration finish read from the original data to the final control signal output, thoroughly get rid of the dependence on industrial control;
By controlling the keyboard Settings of different pulse equivalent and motor running parameters, can be in relation to the carving machine is suitable for various occasions, high control precision, strong commonality.
