G00 is an accelerated move command. Code G00 is used to perform accelerated movement to a specific point. Accelerated movement is necessary to quickly move the cutting tool to the machining position or to the safe position. Movement is carried out as fast as possible. Accelerated movement is never used to perform machining, as the speed of movement is very high and variable.
The command is modal, acting for subsequent frames of the control program, until the command interpreter finds a command from the same group of commands, for example G01, G02, G03, G05, etc.
