Instruction format: X__Y__Z__; (three-axis simultaneous movement, two-axis simultaneous movement or single-axis movement can be used in the format)
The function of the G00 command is to command the tool end point of the tool center to quickly move to the coordinate position specified by X, Y, and Z. The speed of its movement can be adjusted by the "rapid feed rate" knob on the execution operation panel. It is not specified by the F function.
If the fastest moving speed of the X, Y, and Z axes is 15m/min, and the "rapid feed rate" button is adjusted at:
1. If it is 100%, it will move at the fastest speed of 15m/min.
2. 50%, then move at 7.5m/min.
3. 25%, then move at 3.75m/min.
4. 0%, which is set by the parameter at this time (mostly set to 400mm/min).
As long as the movement is not cutting, the G00 command is usually used, such as rapid positioning from the machine origin to the cutting starting point, Z-axis retraction after cutting, and X and Y-axis positioning to save processing time.
Now explain its usage. The tool is quickly positioned from point A to point B, expressed in absolute value: G90 G00 X92. Y35.; expressed in incremental value: G91 G00 X62. Y -25.;
The path of G00 rapid positioning is generally set to an oblique 45° (also called non-linear positioning) mode instead of moving in a linear positioning mode. When moving in an oblique way of 45°, the X and Y axes move at the same speed at the same time. After detecting the coordinate position of which axis has been positioned, only move the other axis to the coordinate point. If the linear positioning method is used to move, the slope must be calculated each time, and then the X-axis and Y-axis must be commanded to move. This increases the load of the computer and the response speed is slower. Therefore, most CNC machines automatically set G00 as soon as they are turned on. Move in an inclined way of 45°.
