Computer engraving machine and sculpture forming principle

Computer engraving machine, CNC ( 电脑Nnmerical Contro1) , it is a kind of can carry CNC engraving process automatic control engraving machine movement of the machining system, it is usually calculated by the carving process, the system ( Including computer and carving software) , nc device, spindle control system and the feed control system. Carving process computing system composed of computer and engraving software, on the computer by digital graphics, engraving software will need generate program each step of the sculpture. Carving process is composed of a series of consecutive nc instructions, used to control the spindle speed, feed rate, tool change, sport suspension, etc. Because of these instructions are ultimately in the service of tool motion, so the sculpture program, also known as tool path to the file.
carving software according to the design pattern and automatically calculate the movement of tools, namely knife site, and write them carving process. Computer engraving machine CNC system from sites of sculpture program reads the knife after automatic calculation of each axis movement, continuous send pulses to the motor, to control the movement of the various shaft, eventually do the actual carving processing. Complete carving process includes the following instruction:
1) Tool instructions, including change knife, the knife, etc;
　　2) Spindle instructions, including spindle drive stops, spindle speed;
　　3) Sports instruction, including rapid positioning, a straight line, arc, its shape and feeding speed;
　　4) Other instructions, including the state of the cooling system, the status of lighting system, etc. ;
