CNC router machine, the CNC (Computer Numerical Control), is a way to automatically control the loading of CNC engraving machine carving motion processing system, which is usually calculated by the engraving process systems (including computer software and sculpture), CNC machine, spindle control system and feed control system. Engraving system consists of a computer program to calculate the composition and engraving software, the software on your computer will need carving carved by the digitizer, the program generates every step of the carving. Sculpture program is composed of a series of consecutive numerical order, and to control the spindle speed, feed rate, tool, sports suspension and so on. Because these instructions are for the ultimate tool movement services, so carving is also known as tool path file. According to design drawings and engraving software tool automatically calculates the position of the tool movement, that knife sites, and write them carving process. CNC engraving process from the point after reading the cutter axis automatically calculates the movement of each component, continuously send pulses to the motor to control the movement of each axis, the final completion of the actual engraving process.
Complete CNC router programs include the following command:
(1) The tool instruction, including the ATC, the knife;
(2) spindle commands, including the opening to stop the spindle, spindle speed;
(3) motion commands, including fast positioning, go straight, take the arc, and the cutting speed of aliasing;
(4) other instructions, including the state of the cooling system, lighting system status
